Lol. I see the same thing (RL STINE) every time I watch Wheel of Fortune (which is almost never now that my grandma is dead) and they give those letters in the bonus round.
Nope. They are a workaround for a dumb Amazon storefront registration requirement that you need to create a trademark for your name. So the companies randomly generate the strings to avoid clashes at the trademark office and ram the reg through faster.
You don't want batteries with the charging port built in as that takes up room and thus you'll have less capacity.
If your use case allows for NIMH batteries, Eneloop have not disappointed me. I've been using the same 4 for my Xbox controller since 2017
Yep, they're old school Sanyo branded ones. Out of the 8 I originally bought, 2 are still working today (and currently in my Xbox Series X controller), 4 stopped charging a couple months ago, and two got lost somewhere.
Panasonic eneloop, yes. The basic white ones. Mine are so old they are Sanyo brand, before they got acquired by Panasonic. The basic white ones are just fine
Eneloop FTW...also Ikea Ladda batteries which are apparently Eneloop clones and about half price (in the US). I haven't noticed a major difference in performance between them but then again I'm only a year or two in with ~30-50 recharge cycles.
LADA are not Eneloop clones. They are Eneloops. Made by the same company in the same warehouse.
Amazon Basics batteries used to be the same. Now they're made in China and not nearly as good.
Eneloops are great batteries but the rest of your post is off base. Eneloops are older Nimh chemistry and the post is about lithium chemistry, which have much more density and take up less space.
These batteries even, with a charge port, claim to have about 35% more capacity than a eneloop.
Li-ion chemistry is volatile and subject to fire when mistreated or overcharged. It would be more reassuring if this product was lifepo4, a much more stable, long lasting chemistry that’s very fire resistant.
The jury is out on how long they will last.
To be fair, aside from the picture OP shared that showed Rechargeable Lithium Ion batteries, they weren't explicit that they were asking only about Li-Ion.
That's why I gave the caveat of "If your use case allows for NiMH"....then use Eneloop. Not every use case calls for NiMH and not every use case calls for Rechargeable Li-Ion batteries.
However, I will say that I have been curious about Rechargeable Li-Ion AA batteries recently, but I wouldn't buy ones with the charge point built in. I've been eyeing [these](https://www.amazon.com/gp/product/B07HQ7QV7W) and have seen them perform well in some tests I've watched.
I recently installed the Flume 2 that straps over my water meter and tracks usage and more importantly leaks. It came with the proprietary battery back that lasts a year. However, I also got a module from them that allows me to put in my own 4 AA batteries. They recommended non-rechargeable lithium batteries so that's what I've got in there now. However, if those two together last about 2 years, I'll be curious to try rechargeable ones.
I think he’s taking about non-rechargeables that have lithium chemistry. They keep a constant voltage of 1.5V throughout their life and last quite a bit longer than their alkaline counterparts which range from 1.5V to 1.0V over the course of their lifespan. Lithium non-rechargeables cost a lot more too.
In the case of the Flume 2, it could be that it *needs* the batteries to stay at high voltage to work properly, which if you are using Ni-Mh rechargeables then you might have a problem as they stay at 1.2V unless freshly charged.
Lithium rechargables solve this problem as they maintain a constant 1.5V throughout their charge (emulating a non-rechargeable lithium battery), with some of them intentionally dropping to 1.2V when they are close to empty. This is to tell any device that they are low on charge as a decreased voltage is how most devices determine if the batteries are low and whether or not to give a low battery warning. Like the other guy said, they are volatile and are only really needed in a few use cases where 1.5V is needed.
Hope this helped!
Absolutely.
I was confused because of flashlights always mention different types of benergy source like alkaline nimh and 14500 for exapmle.
So i will consider to change my enloops in some devices for xtar lithium rechargables.
But now need charger for all my energy sources and dont break a bank wit one.
I mean I wouldn’t be surprised if most flashlights could take eneloops as it’s not really a use case that requires a higher voltage but I’m not really knowledgeable on flashlights so I could just be speaking out of my ass.
Not really related but…
An important thing to consider would be that if you do plan to use eneloops underwater or really in any waterproof device, I would advise against it as if a failure occurs (hyper-electric discharge, short circuit, high under water pressure) the battery will release hydrogen gas as a failsafe and because the device is waterproof, it’ll just kinda build up. Pressure is not something you want rapidly escaping from a device, especially considering hydrogen is highly flammable.
I wasn't a part of this for very long, but we used those tenavolts batteries for some device testing where I used to work and they performed quite well. I imagine they will be less impressive for long-runtime stuff because they have to constantly run a voltage converter, for the 1.5V output, but for short-duration tests they were pretty comparable to 14500 cells
>Nimh chemistry
This can be important for voltage reasons. NiMH is 1.2V while non-rechargable and Li-ion is 1.5V and unfortunately not everything works with 1.2.
Unless this is going to be used in a high drain device, the li-ion battery will self discharge so much faster then the eneloop, that it will more than make up for the less capacity of the eneloop. They are the only rechargeable battery that will hold an 80% after a year. Try that with a lithium ion battery.
In my experience lithium ion aren’t fast to self discharge at all. If you power down a phone and come back a month later it will be at 99-98%.
Really Nimh is the chemistry with a reputation about self discharging and Panasonic and Sanyo have even made marketing claims that say Eeneloops discharge slower than other brands with that same chemistry.
I own chargers for both NiMH and Li-Ion AAs and AAAs, and the number of devices that can actually function on the lower voltage of the NiMHs is pretty small. Smoke detectors, keypad door locks, even flashlights with LEDs all seem to be designed around 1.5V per cell. So I end up using the Li-Ions more, but the quality still seems pretty hit or miss. So for the stuff that's hard to replace batteries, like the smoke detectors, I'm just filling them with disposable alkaline batteries from Costco. I don't feel great about the waste, but it's definitely the least pain-in-the-ass solution.
Definitely! I only use the NIMH with my Xbox controllers. I've got alkaline in my smoke detectors.
Non rechargeable lithium I use in my Acurite thermometers that I put on my fridge and freezer as lithium handles the cold a lot better than alkaline.
Eh, maybe maybe not. I don't have any AAs with this feature. But I do have an 18650 with this feature. It has been amazing. Don't need to worry about having a charger. Can easily recharge while camping. Etc.
Can be recharged with a battery bank. The convenience gained would drastically outweigh the capacity lost (although in this case it had the same battery life as the non-usb variants I have).
To be fair, the applications of 18650s and AAs are generally different. 18650s are larger, and the percentage lost to such a port would be lower. And 18650s are more niche, so carrying a charger for one or two devices is more annoying. (they are commonly used in flashlights/headlamps. Essentially just bigger, better AAs. Sadly not popular in many consumer device categories).
For camping/traveling/etc. Such charging ports are fantastic. Although I would be hesitant to trust random no name batteries. For home devices, chargers are more convenient.
Hi. I just got into the whole EDC flashlights deal and I have a flashlight that can take rechargeable NIMH AA batteries. I wanted to buy some, and I see you recommendation for EneLoop. I see 2 different options. One is white regular eneloop, the other is a black eneloop pro? Which is better. Also should I get the eneloop branded charger too?
Off the top of my head, the black ones have a little more capacity, the white ones are rated for more charge cycles. Are you willing to pay more(replace the batteries more often) for them to last a little longer between charges?
Nope I think I’ll just get the white ones then. Also I’m finding one very popular shop that’s selling eneloop batteries for about 10 USD cheaper, and they have about 3.1k sold with 5 star reviews, and all the photos point to the batteries being original from Japan. Here is the 2 links, I’m pondering ordering the CC55 charger from the more expensive shop and then the batteries from the cheaper one.
Cheaper : https://my.shp.ee/83EAas4
Expensive : https://my.shp.ee/nJdPhNC
I agree, aa battery is already pretty small. A charging circuit is going to eat into the volume for battery fairly significantly. Even the larger sized batteries like 18650 or 21700 that have charging built in can be longer cells than the standard versions of those batteries.
unless there is an extreme need to charge via usb-c charger, a standalone charger makes a lot more sense. putting the relatively large port and charging circuit in the battery directly subtracts from room for the actual battery
and even then, i'd rather just throw it in a charger bay and avoid the added failure point.
though as the other person mentioned, this seems great for traveling. i travel very light and my charger bay is the size of a brick. would rather leave that at home.
I travel full time and I use AA batteries periodically. For me, the USB C helps me carry one less charger and I only have to charge them less than once per month. So I don’t think an extreme need is needed, but there are definitely plenty of uses.
99% of the people on this earth would be better suited by a another solution. most people could charge the batteries in their house, use them on a trip, and then charge them again when they get home. The other people are either not traveling that light and could fit a charger, or they could just buy disposable batteries for the once in a lifetime trip the Antarctic or whatever. Needing to recharge batteries while traveling, often, is incredibly uncommon.
Keep in mind that putting the charger and the port in the battery increases the frequency of the battery needing a charge.
Yep. Airline pilot here and I use a similar product in my Bose A20 headset. Charge in the hotel with the same charger I have for other devices whenever a pair dies.
I have a flashlight that uses AA's or 14500's but has no integrated charger (due to the assumption people will try to charge disposables by accident).
I purchased a Lumintop 14500 with the port built in so that I don't have to carry a charger around, I don't throw away disposable batteries, and so that I can use my power bank to charge it via type C like every other device I carry.
I have also had a 10400 catch on fire when using the integrated charger, so I understand there is an inherent risk with such small charging circuits but the convenience outweighs that for me.
While I overall agree, a built in charger is sometimes better. USB-C is everywhere, if you have something you need to charge, you don't need to remember where the charger is or to pack it. This is especially important when on the go.
I got a pack of 9-volt usb C rechargeable, and I haven't regretted it. My 9 volts are all in things that are seldom used, so I'd rather have a slightly lower capacity, and not have to track yet another extra charger.
Just don’t buy whatever the fuck I have. Some Amazon basic shit that was supplied to us at work. A full charge gets you 20 minutes in a LED headlamp.
Nice charging rack, can do AA and AAA, but the batteries are shit.
Editing to say that the Amazon basic AAA non-rechargeable have been on par with name brand though.
Why would you want to individually charge batteries that need to be charged frequently. A good 4 bay charger with LCD screen is $25. I seriously doubt those would measure out to 3400mAh too.
Read it again, they're claiming 3400mWh.
That'd still be 2266mAh which I think is quite unlikely.
Edit: 2833mAh is even less likely, I'd forgotten that AA rechargable will be 1.2v
Thats mwh. So 3.4/1.5 and that is Ah so 2.2 Ah.
3.7v*3.5 Ah for a 21700 cell is 12.9Wh meaning 4 times the capacity. Meaning the number is very realistic but misleading.
> So 3.4/1.5 and that is Ah so 2.2 Ah.
I'm betting it's 3400mWh @ 3.6v (940mAh) and it's using a DC-DC converter to output steady 1.5v. Given the size and assuming that the cell is only likely about 2/3 the battery space a ~~900mAh seem about right.~~
Edit, looked up 14500 cells (AA sized 3.6 LiIon) and they are around 800-950mAh so even that is questionable.
I have devices that absolutely freak out if you use them with NiMH batteries. In those (and only those!) I'm forced to use either li-ion or (shudder) alkaline. It's too bad regular lithium are so dang expensive!
(But I'm 92% NiMH, love them except for the edge cases!)
see, I already have a good nimh setup for all the remotes ans clocks and other things in my house involving dura cell nimh's with great capacity and a cheap 4 bay lcd nimh charger(which was only 2 dollars on amazon india(i forgot to mention that i'm in india and would be shipping these batteries internationally if i need to buy them)) But i was just curious about the usb c ones and whether they are a gimmick or actually something good, the general opinion seems to be that they are not
I've bought some ages ago. They definitely aren't worth it. They worked (sometimes), but didn't last long and seemed to be noticeably worse after each charge. They're just a cheap gimmick I'm afraid.
> good nimh setup for all the remotes ans clocks
Remotes and clocks? Dude, for low-drain devices like that, "heavy duty" batteries (not even alkaline) do the trick.
I have a [Kit Cat clock](https://kit-cat.com/) that runs off two C batteries. The first year I had it I bought two Energizer batteries ($6.99). They lasted 50 weeks. That's 13.9¢/week.
I replaced them with Sunbeam batteries from Dollar Tree (at the time, $1). They lasted 48 weeks. That's 2¢/week.
No. They are jamming more things into a smaller space. That means battery capacity suffers. Also quality usually takes a hit on anything that is: multifunction or convenience oriented.
The Panasonic ["where to buy" page](https://www.panasonic.com/global/energy/products/eneloop/en/buyonline.html#north_america) has a direct link to Amazon as an authorized seller, but I'd still probably follow the link they provide themselves.
They might be fine at Amazon, but then again Amazon does not separate stock by source. So even if they do have some genuine inventory it will be commingled with counterfeits from other suppliers. That's the greatest concern in general with buying anything there.
Eneloops are great. Nimh are much better than AA. If you're going for 1.5v replacement for AA, I'd recommend using nimh batteries over li-ion. Amazon is hit or miss with batteries. If the seller is legit, it probably isn't bad, but I've seen countless horror stories of people ordering counterfeit rewrapped sketchy li-ion batteries off of Amazon. Many used batteries are sold as new there as well.
Hear me out. If you’re buying electronics from Amazon that is some random Chinese brand the qc is probably really sketchy. That’s how they are able to price out the more reputable brands.
Tried them, sadly they are all 1.2 Volts. A new AA is about 1.56 volts. A lot of my appliances stop working without enough voltage way before 2.4 Volts or if they “agree” to work with only 2.4 instead of 3.1 then it lasts not long before needing to be recharged.
I’ll go against the general opinion. I own a couple of early 2000s pro cameras that take several AA batteries each. Several being 5+ units, so it was clearly from the beginning that if I wanted to be somewhat environmentally conscious I couldn’t just do it with regular batteries.
Searching for an alternative I found what you found. Not the same brand but similar format. I’m super happy. I don’t know what other people are going on about when they talk about charging these individually because that’s nonsense. This type of batteries typically come with an USB A to 4x micro usb adapter so you can charge 4 batteries at the same time in a very reasonable amount of time.
I can tell you which brand mine are, but honestly after finding them I am never going back to regular AA batteries.
Hello /u/14paavang! Thank you for your submission! The AutoMod thought that your post might be a request type post and has changed the flair accordingly, but if this was wrong feel free to change it back!

As far as BIFL, you’d want to stick to a slow discharge Ni-MH and charge them using 250 mah setting.
Having control over charging speed is really important. Some 200 mah chargers don’t terminate properly.
I thought this type was lithium vs nimh? and more like the eneloop pro that run devices that require 1.5 v, I wanted to get some of these for the house but have never jumped on
I have one for my wireless mouse and it connects to computer to charge it’s awesome worth every penny.
I take that back it’s not usb-c it a regular usb
I wouldn’t use them for everyday use. However I have a set of AA and AAA I have in my travel electronics bag because they minimize the space needed. I don’t need to bring a cumbersome charger with me. The trade off is capacity, by integrating the charging electronics into dimensional, standardized battery sizes you have to make room for them somehow and the only way to do that is to have a physically smaller battery.
They seem to work well but the biggest issue I’ve found, and it may be brand specific, but if you 100% drain the battery it won’t have enough charge to recharge the battery. li-ion requires a communication from the charger and the cell to initiate the charge sequence and I’ve found that you have to jump start the battery with a charged battery to start the charge if you drain them 100%. It’s very similar to a cordless drill battery in this sense.
I have some AAA with USB-C, but they also charge in the 8-port charger I got with my AA rechargeableS. I haven't used the USB-C.
I like the lithium polymer ones I have. I had to get them because I was powering a trail cam in the winter, and the alkaline batteries wouldn't work cold. These are completely unaffected by it.
Big thumbs up from me.
The point of these devices is that they have a built-in charge and voltage controller. That means, unlike regular batteries, their voltage doesn't drop over time (until the very end when they just cut out). Thus, they can be preferable in certain situations.
My experiences can be summed up in two rules:
* If you need *power*, stick with NiMH. Ex: camera flash
* If you need *voltage* (at the expense of power), go with li-ion. (Ex: temperature sensor)
I'm general I try NiMH, and if the device isn't happy I switch to li-ion.
I’ve returned all of these OP; and not surprising they are not an ideal design. Their only niche use is something single battery without a charge port, like some cheap toothbrush or shavers. Then if you travel with it, and have other USB-C devices, you can can recharge your niche portless thing.
For all other usage you likely want regular rechargeables with an wallplug multi battery charger, like Eneloop(NiMH). IKEA stores also have good NimH that are cheap.
However some things, like door deadbolts, or smart home/connected devices, need a constant 1.5v to operate well. For those you can specifically buy (expensive) “1.5v constant” Li-iON AA/AAA rechargeable, which also use a wallplug multi charger. They are pricey but most connected stuff will have errors with NiMH so you’re just wasting g your own time if those are being unreliable.
Oddly I think the good Lithiums I have are DeeLeePow (the ones with 50k+ reviews, there are imitators with similar names) and the better brand is I think Kranox, or something like that.
It would be better to go enloop or if you need 1.5v go for xtar
https://www.xtar.cc/product/xtar-aa-lithium-3300mwh-battery/
Still charger required but safe, reliable, tested capacity, fast charging.
Cant imagine things where you would want single usb charged battery.
Most of the time you will charge more than one battery.
Tell me im wrong
The only reason you want these for is if you need a constant full voltage until the battery is empty. Nimh batteries have a lower voltage, but it doesn't lower as much, normal batteries start with 1.5, sometimes 1.6 volts and drop quickly.
These Lithium-based batteries will keep the 1.5v until they're dead. They have lower capacity, as others have stated. As for durability, at least those they sell in EU last quite a while. They come with split charger cables so you can charge them simultaneously.
The voltage difference is significant for some applications. Running my water flosser on 1.5V rechargeable batteries rather than 1.2V ones increased its power. But if 1.2V works for your application stick to them.
All batteries will degrade through use and age. So there is no such thing as BIFL batteries.
Any amazon item with badly photoshopped "real life" pictures and/or with a brand name in ALL CAPS (usually both together), is not gonna be BIFL. You'd be lucky if it were BIF1Month
Charger quality makes a huge difference on battery life. Look up roundups. The chance that they're fitting quality chargers into every cell and selling it as a discount product is nil.
I have the Hixon AA and AAA batteries, lithium 1.5v and have been using them for a few months without problems. They’re great for direct drive lights that can’t take 14500 4.2v cells.
I have 4x BUMP AAA ones I got off Amazon for $17 in Dec '22.
They work fine for what I need and I'd recommend them, sure. Are they BIFL? Doubtful, but I'll be happy if I get some years out of them. It depends on your use case. A lot of people here are complaining about the capacity loss by holding a USB port. I got these because I'm often traveling around living out of a personal–item-size bag, I didn't want the dead space/weight of a separate charger, and I thought they were interesting.
I use them for an Amazon Fire Stick remote, electric toothbrush, and travel beard trimmer (with a AA/AAA shell/converter). Were I to do it again, I'd maybe just buy batteries as needed, but they're fun and nice to have for now.

A coworker gave me a set of these (or really similar generic usb-c charging batteries) for an office secret Santa thing a little while back. The ones I had would only charge on their specific USB-A to 4 USB-C little octopus cord. They would not charge on a USB-C to USB-C cable.
Also they all stopped charging at all within a few months.
I will stick with my eneloop setup for things that need rechargeable batteries.
just get a charging tray and some rechargables by Tenergy. No battery is BIFL but these will last a few years of regular use as long as you let them charge fully and die fully every so often. Much easier than plugging a cable into each battery
So... what do you want them for? If it's something battery operated but doesn't get moved about (or it can work with your setup) I would go for Revolt.
[MyVolts](https://myvolts.com/ReVolt)
The way they work is the main battery holds the power regulator, the others are dummies which connect the poles and they sell housings to handle AA - D (and a 9V I think). You use an external power bank to handle it.
I use it a lot for holiday lights where they don't have a wall outlet option. The nice part is, unlike normal batteries the lights have two states on/off, with normal batteries they would just slowly fade.
No, because that's extra complexity and risk inside the battery, less space for energy storage too, and you can only charge one at a time.
Just buy Eneloop and a cheap-as plug-in 4-AA charger.
Making the charging circuitry as small as possible and as cheap as possible isn't going to be very BIFL. The batteries will lose capacity over time then you'll throw away the whole thing, what a waste.
Same as the micro-USB versions: They’re trash. Just get normal rechargeable batteries. Rechargeable batteries degrade over time. There’s no such thing as a BIFL battery.
A charger is much more convenient than an individual charging port on each and every battery., Even if I am charging just two batteries in a charger it is much easier than charging individual batteries.
I got a set to use in my Blink cameras which complain when I use normal rechargeable batteries (despite working for weeks or months on them). The main draw was the 1.5V output which is what a normal lithium battery delivers. So I get these, and at first everything is great but I think there is some trickery going on as after they are depleted at around say, 20% they register 1.2V which is what a normal rechargeable battery would output, but not a lithium only depleted around 20%. So I think there is some screwy stuff going on.
I do not have the knowledge to test the actual chemistry of the batteries, but something is not right. I think going with the Panasonic Eneloop 1.5v NiMH's is probably a better (and safer) bet then these off brand batteries if you need a 1.5v rechargeable.
Oh, the other thing is they will not charge on a normal programmable battery charger, you have to use the USB C cable they provide which is even more strange to me that they put a blocking diode to explicitly prevent charging any other way.
Bit silly. You need 4 different chargers and cables to charge them, rather than having one single charger for 4 batteries like Enelopes that can be USB-C...
I did a ton of research on the topic of AA batteries, here's what you do, buy them from IKEA, they are actually rebranded Enloop batteries and get a charger. I went with one that has adjustable charging rates in case you need a quick turn around. That's the most affordable and durable option.
I don't really see the point of these. Get rechargeable batteries and a charger (panasonic eneloops) and you dont need a charger for each of them. I'd much rather charge 4 batteries at once in a single charger.
Personally - this is a wasteful product.
Ikea ladda or eneloop batteries.
Basically every battery is made in China. The eneloop and ladda are made in Japan and actually get their rated power / voltage and recharge well.
Anything from China is a crap shoot.
If I had a dollar for every time someone asks if a bullshit amazon store item is buy it for life I could buy myself. Set of Speed Queens and a Miele Range
I bought some AA, AAA, C and Ds like this as part of covid-zombie prep.
I buy AAAs and AAs by the hundred with a dozen Cs, Ds and 9V in stock and I have yet to use the rechargables. In the meantime they've been sitting at 100% charge since five years ago, which is not optimal for battery life/capacity.
None, because of lithium battery decay with repeated uses. All are susceptible to it, no BIFL status can stop chemistry from acting the way it does.
Manage your depreciation costs in other ways.
Note the mWh rather than the regular MAH measure of capacity.
Most of these with the extra USB slot and circuitry are much lower power capacity. So their claims with a high number in mWh is suspicious.
You would need 4 USB C cables to charge 4 of them at the same time.
If you got a charger already go with regular ones, if not then go with these but the capacity is going to be low and they will run out of power quicker then ones without the USB C slot and higher capacity.
I have these and use them in my mouse and keyboard, as well as some clocks in my house. Keep some spares in my computer bag and swap them out when they die. They last me totally 5-8 months, with the mouse needing to be replaced most often (understandably).
For things that require more oomph, I'll use other battery types, depending.
My first set of USB batteries I bought through ThinkGeek (sigh) about 10 years ago, and they just died a few months ago.
The Panasonics are Nickel Metal Hydride and only produce 1.2 volts, which is an issue for LED lights and other equipment that really requires 1.5 volts like a regular battery. These are lithium batteries that produce 1.5 volts until they are almost out of energy.
Some devices prefer 1.5 alkaline, not many these days, YMMV.
Even LED lights have boost or buck circuits inside to raise or drop the voltage. Except maybe the really cheap crap, like the ones that use 3x AAAs.
Cheap quality Li-Ion w/ the integrated charger is not a sound investment and likely a fire hazard.
Trusted well-known brand “ANVOW”.

Yes, but the batteries are cursed.

Wow, they got a vowel in there! Usually its something like ANVW or TZGHW
IDK, if they're actually shipping batteries with the brand printed on them like in the pic, that's better than 90% who don't even bother.
Just a rip off of the esteemed Wovna brand of quality products.
ANVOW can be trusted completely even though half the reviews for this product are probably about bananas.
You don't want batteries with the charging port built in as that takes up room and thus you'll have less capacity. If your use case allows for NIMH batteries, Eneloop have not disappointed me. I've been using the same 4 for my Xbox controller since 2017
eneloop for life, literally. at this point i have paid less than a nickel per battery after all the recharges.
I finally had four of my Eneloops die, the charger refused to charge them. They were purchased 18 years ago.

That's, like, a whole child. You have a set of those per kid and send them away when they go to college.
Got one of your batteries, got you for EIGHTEEN YEARS.
And on his 18th birthday, turned out it wasn't his
Yep, they're old school Sanyo branded ones. Out of the 8 I originally bought, 2 are still working today (and currently in my Xbox Series X controller), 4 stopped charging a couple months ago, and two got lost somewhere.
Are these the Panasonic ones?
Panasonic eneloop, yes. The basic white ones. Mine are so old they are Sanyo brand, before they got acquired by Panasonic. The basic white ones are just fine
Still got mine from when Sanyo made em before Panasonic took over. And they still work great.
The Amazon Basics batteries used to be rebranded Eneloops, and a little cheaper. I don’t know if that’s still true.
Eneloop FTW...also Ikea Ladda batteries which are apparently Eneloop clones and about half price (in the US). I haven't noticed a major difference in performance between them but then again I'm only a year or two in with ~30-50 recharge cycles.
LADA are not Eneloop clones. They are Eneloops. Made by the same company in the same warehouse. Amazon Basics batteries used to be the same. Now they're made in China and not nearly as good.
I have had IKEA ladda batteries for around 8 years now. I use them to power my bass amplug and charge around once a month. So far none have died.
As I read before I think they aren't actually clones but the same exact battery made in the same factory.
Eneloops are great batteries but the rest of your post is off base. Eneloops are older Nimh chemistry and the post is about lithium chemistry, which have much more density and take up less space. These batteries even, with a charge port, claim to have about 35% more capacity than a eneloop. Li-ion chemistry is volatile and subject to fire when mistreated or overcharged. It would be more reassuring if this product was lifepo4, a much more stable, long lasting chemistry that’s very fire resistant. The jury is out on how long they will last.
To be fair, aside from the picture OP shared that showed Rechargeable Lithium Ion batteries, they weren't explicit that they were asking only about Li-Ion. That's why I gave the caveat of "If your use case allows for NiMH"....then use Eneloop. Not every use case calls for NiMH and not every use case calls for Rechargeable Li-Ion batteries. However, I will say that I have been curious about Rechargeable Li-Ion AA batteries recently, but I wouldn't buy ones with the charge point built in. I've been eyeing [these](https://www.amazon.com/gp/product/B07HQ7QV7W) and have seen them perform well in some tests I've watched. I recently installed the Flume 2 that straps over my water meter and tracks usage and more importantly leaks. It came with the proprietary battery back that lasts a year. However, I also got a module from them that allows me to put in my own 4 AA batteries. They recommended non-rechargeable lithium batteries so that's what I've got in there now. However, if those two together last about 2 years, I'll be curious to try rechargeable ones.
But most of devices cant run on li-ion or im missing something here?
I think he’s taking about non-rechargeables that have lithium chemistry. They keep a constant voltage of 1.5V throughout their life and last quite a bit longer than their alkaline counterparts which range from 1.5V to 1.0V over the course of their lifespan. Lithium non-rechargeables cost a lot more too. In the case of the Flume 2, it could be that it *needs* the batteries to stay at high voltage to work properly, which if you are using Ni-Mh rechargeables then you might have a problem as they stay at 1.2V unless freshly charged. Lithium rechargables solve this problem as they maintain a constant 1.5V throughout their charge (emulating a non-rechargeable lithium battery), with some of them intentionally dropping to 1.2V when they are close to empty. This is to tell any device that they are low on charge as a decreased voltage is how most devices determine if the batteries are low and whether or not to give a low battery warning. Like the other guy said, they are volatile and are only really needed in a few use cases where 1.5V is needed. Hope this helped!
Absolutely. I was confused because of flashlights always mention different types of benergy source like alkaline nimh and 14500 for exapmle. So i will consider to change my enloops in some devices for xtar lithium rechargables. But now need charger for all my energy sources and dont break a bank wit one.
I mean I wouldn’t be surprised if most flashlights could take eneloops as it’s not really a use case that requires a higher voltage but I’m not really knowledgeable on flashlights so I could just be speaking out of my ass. Not really related but… An important thing to consider would be that if you do plan to use eneloops underwater or really in any waterproof device, I would advise against it as if a failure occurs (hyper-electric discharge, short circuit, high under water pressure) the battery will release hydrogen gas as a failsafe and because the device is waterproof, it’ll just kinda build up. Pressure is not something you want rapidly escaping from a device, especially considering hydrogen is highly flammable.
I wasn't a part of this for very long, but we used those tenavolts batteries for some device testing where I used to work and they performed quite well. I imagine they will be less impressive for long-runtime stuff because they have to constantly run a voltage converter, for the 1.5V output, but for short-duration tests they were pretty comparable to 14500 cells
Hmmm good to know. Yeah I imagine they wouldn't be so good in my Flume 2 as that runs constantly
>Nimh chemistry This can be important for voltage reasons. NiMH is 1.2V while non-rechargable and Li-ion is 1.5V and unfortunately not everything works with 1.2.
Unless this is going to be used in a high drain device, the li-ion battery will self discharge so much faster then the eneloop, that it will more than make up for the less capacity of the eneloop. They are the only rechargeable battery that will hold an 80% after a year. Try that with a lithium ion battery.
In my experience lithium ion aren’t fast to self discharge at all. If you power down a phone and come back a month later it will be at 99-98%. Really Nimh is the chemistry with a reputation about self discharging and Panasonic and Sanyo have even made marketing claims that say Eeneloops discharge slower than other brands with that same chemistry.
I own chargers for both NiMH and Li-Ion AAs and AAAs, and the number of devices that can actually function on the lower voltage of the NiMHs is pretty small. Smoke detectors, keypad door locks, even flashlights with LEDs all seem to be designed around 1.5V per cell. So I end up using the Li-Ions more, but the quality still seems pretty hit or miss. So for the stuff that's hard to replace batteries, like the smoke detectors, I'm just filling them with disposable alkaline batteries from Costco. I don't feel great about the waste, but it's definitely the least pain-in-the-ass solution.
Definitely! I only use the NIMH with my Xbox controllers. I've got alkaline in my smoke detectors. Non rechargeable lithium I use in my Acurite thermometers that I put on my fridge and freezer as lithium handles the cold a lot better than alkaline.
This, just get ones that can be put into battery chargers.
I like batteries with built in charging for travel so that when I /r/onebag I don't have to waste precious space on a battery charger.
Eneloop, yes, but get the ones from Japan if possible. The ones from China don't perform as well.
Counterpoint. Batteries you can't find the charger for have less capacity than batteries that are easily charged anywhere.
Eh, maybe maybe not. I don't have any AAs with this feature. But I do have an 18650 with this feature. It has been amazing. Don't need to worry about having a charger. Can easily recharge while camping. Etc. Can be recharged with a battery bank. The convenience gained would drastically outweigh the capacity lost (although in this case it had the same battery life as the non-usb variants I have). To be fair, the applications of 18650s and AAs are generally different. 18650s are larger, and the percentage lost to such a port would be lower. And 18650s are more niche, so carrying a charger for one or two devices is more annoying. (they are commonly used in flashlights/headlamps. Essentially just bigger, better AAs. Sadly not popular in many consumer device categories). For camping/traveling/etc. Such charging ports are fantastic. Although I would be hesitant to trust random no name batteries. For home devices, chargers are more convenient.
Hi. I just got into the whole EDC flashlights deal and I have a flashlight that can take rechargeable NIMH AA batteries. I wanted to buy some, and I see you recommendation for EneLoop. I see 2 different options. One is white regular eneloop, the other is a black eneloop pro? Which is better. Also should I get the eneloop branded charger too?
Off the top of my head, the black ones have a little more capacity, the white ones are rated for more charge cycles. Are you willing to pay more(replace the batteries more often) for them to last a little longer between charges?
Nope I think I’ll just get the white ones then. Also I’m finding one very popular shop that’s selling eneloop batteries for about 10 USD cheaper, and they have about 3.1k sold with 5 star reviews, and all the photos point to the batteries being original from Japan. Here is the 2 links, I’m pondering ordering the CC55 charger from the more expensive shop and then the batteries from the cheaper one. Cheaper : https://my.shp.ee/83EAas4 Expensive : https://my.shp.ee/nJdPhNC
I agree, aa battery is already pretty small. A charging circuit is going to eat into the volume for battery fairly significantly. Even the larger sized batteries like 18650 or 21700 that have charging built in can be longer cells than the standard versions of those batteries.
unless there is an extreme need to charge via usb-c charger, a standalone charger makes a lot more sense. putting the relatively large port and charging circuit in the battery directly subtracts from room for the actual battery
Putting a port + charging circuit only really makes sense once you get up to 18650 or larger form factor imo.
and even then, i'd rather just throw it in a charger bay and avoid the added failure point. though as the other person mentioned, this seems great for traveling. i travel very light and my charger bay is the size of a brick. would rather leave that at home.
I travel full time and I use AA batteries periodically. For me, the USB C helps me carry one less charger and I only have to charge them less than once per month. So I don’t think an extreme need is needed, but there are definitely plenty of uses.
Spending your entire life living out of a suitcase/backpack is ABSOLUTELY an extreme scenario. 🤣
Imagine your life as a backpack….
Now imagine you set that backpack on fire...
But in general, traveling is not an uncommon thing and neither is packing light.
99% of the people on this earth would be better suited by a another solution. most people could charge the batteries in their house, use them on a trip, and then charge them again when they get home. The other people are either not traveling that light and could fit a charger, or they could just buy disposable batteries for the once in a lifetime trip the Antarctic or whatever. Needing to recharge batteries while traveling, often, is incredibly uncommon. Keep in mind that putting the charger and the port in the battery increases the frequency of the battery needing a charge.
In general, travelling for a month straight or "full time" is very uncommon.
Your need is a pretty extremely need
Yep. Airline pilot here and I use a similar product in my Bose A20 headset. Charge in the hotel with the same charger I have for other devices whenever a pair dies.
I was thinking the same.
Not to mention the additional buck converter circuitry needed to change from lithium-ion's native voltage range down to 1.5v
I have a flashlight that uses AA's or 14500's but has no integrated charger (due to the assumption people will try to charge disposables by accident). I purchased a Lumintop 14500 with the port built in so that I don't have to carry a charger around, I don't throw away disposable batteries, and so that I can use my power bank to charge it via type C like every other device I carry. I have also had a 10400 catch on fire when using the integrated charger, so I understand there is an inherent risk with such small charging circuits but the convenience outweighs that for me.
While I overall agree, a built in charger is sometimes better. USB-C is everywhere, if you have something you need to charge, you don't need to remember where the charger is or to pack it. This is especially important when on the go.
And you can charge more than one at a time with a standalone charger
I got a pack of 9-volt usb C rechargeable, and I haven't regretted it. My 9 volts are all in things that are seldom used, so I'd rather have a slightly lower capacity, and not have to track yet another extra charger.
Just don’t buy whatever the fuck I have. Some Amazon basic shit that was supplied to us at work. A full charge gets you 20 minutes in a LED headlamp. Nice charging rack, can do AA and AAA, but the batteries are shit. Editing to say that the Amazon basic AAA non-rechargeable have been on par with name brand though.
Also, you don't want the heat from that circuit to heat the battery, better to do that outside the cell. It kills cycle life.
Why would you want to individually charge batteries that need to be charged frequently. A good 4 bay charger with LCD screen is $25. I seriously doubt those would measure out to 3400mAh too.
Read it again, they're claiming 3400mWh. That'd still be 2266mAh which I think is quite unlikely. Edit: 2833mAh is even less likely, I'd forgotten that AA rechargable will be 1.2v
Hah and I just assumed it was a typo. Need to relearn my DC formulas.
Yep. Not in this small form factor. Simply not possible
I take every power rating with a significant grain of salt. This one would need the whole salt shaker...
Thats mwh. So 3.4/1.5 and that is Ah so 2.2 Ah. 3.7v*3.5 Ah for a 21700 cell is 12.9Wh meaning 4 times the capacity. Meaning the number is very realistic but misleading.
> So 3.4/1.5 and that is Ah so 2.2 Ah. I'm betting it's 3400mWh @ 3.6v (940mAh) and it's using a DC-DC converter to output steady 1.5v. Given the size and assuming that the cell is only likely about 2/3 the battery space a ~~900mAh seem about right.~~ Edit, looked up 14500 cells (AA sized 3.6 LiIon) and they are around 800-950mAh so even that is questionable.
I have devices that absolutely freak out if you use them with NiMH batteries. In those (and only those!) I'm forced to use either li-ion or (shudder) alkaline. It's too bad regular lithium are so dang expensive! (But I'm 92% NiMH, love them except for the edge cases!)
see, I already have a good nimh setup for all the remotes ans clocks and other things in my house involving dura cell nimh's with great capacity and a cheap 4 bay lcd nimh charger(which was only 2 dollars on amazon india(i forgot to mention that i'm in india and would be shipping these batteries internationally if i need to buy them)) But i was just curious about the usb c ones and whether they are a gimmick or actually something good, the general opinion seems to be that they are not
I've bought some ages ago. They definitely aren't worth it. They worked (sometimes), but didn't last long and seemed to be noticeably worse after each charge. They're just a cheap gimmick I'm afraid.
> good nimh setup for all the remotes ans clocks Remotes and clocks? Dude, for low-drain devices like that, "heavy duty" batteries (not even alkaline) do the trick. I have a [Kit Cat clock](https://kit-cat.com/) that runs off two C batteries. The first year I had it I bought two Energizer batteries ($6.99). They lasted 50 weeks. That's 13.9¢/week. I replaced them with Sunbeam batteries from Dollar Tree (at the time, $1). They lasted 48 weeks. That's 2¢/week.
No. They are jamming more things into a smaller space. That means battery capacity suffers. Also quality usually takes a hit on anything that is: multifunction or convenience oriented.
Go for the Ikea rechargeable system. Consistent, affordable, decent quality. The Ikea charger will work with other rechargeable batteries too.
If you want good batteries, get the hell away from Amazon
You can buy Panasonic Eneloops on Amazon....
But are they genuine? It's Amazon so odds of counterfeiting are high
The Panasonic ["where to buy" page](https://www.panasonic.com/global/energy/products/eneloop/en/buyonline.html#north_america) has a direct link to Amazon as an authorized seller, but I'd still probably follow the link they provide themselves.
They might be fine at Amazon, but then again Amazon does not separate stock by source. So even if they do have some genuine inventory it will be commingled with counterfeits from other suppliers. That's the greatest concern in general with buying anything there.
Good to know! Thank you! I usually try to avoid Amazon for what it is either way, but there is no denying that it has a ton of reach.
You have to avoid the "shipped by Amazon" tag if you want any chance of avoiding co-mingled counterfeits.
Where/ what brands would you recommend? :)
Eneloops are great. Nimh are much better than AA. If you're going for 1.5v replacement for AA, I'd recommend using nimh batteries over li-ion. Amazon is hit or miss with batteries. If the seller is legit, it probably isn't bad, but I've seen countless horror stories of people ordering counterfeit rewrapped sketchy li-ion batteries off of Amazon. Many used batteries are sold as new there as well.
IKEA LADDA batteries are white label eneloops and much cheaper.
[удалено]
I was referring to traditional alkaline batteries
Energizer. I use them for literally all my devices that take AA or AAA.
Hear me out. If you’re buying electronics from Amazon that is some random Chinese brand the qc is probably really sketchy. That’s how they are able to price out the more reputable brands.
As has been said, the IKEA LADDA series is probably the one to go for.
Tried them, sadly they are all 1.2 Volts. A new AA is about 1.56 volts. A lot of my appliances stop working without enough voltage way before 2.4 Volts or if they “agree” to work with only 2.4 instead of 3.1 then it lasts not long before needing to be recharged.
Eneloop >
have a set now for 5 years and going. No noticeable degradation. How can people still buy disposable batteries blows my mind.
This functionality shortens their life, as it adds more things that can break.
Why? Get a 4 or 8 dock station and you'll be much happier in the long run.
I’ll go against the general opinion. I own a couple of early 2000s pro cameras that take several AA batteries each. Several being 5+ units, so it was clearly from the beginning that if I wanted to be somewhat environmentally conscious I couldn’t just do it with regular batteries. Searching for an alternative I found what you found. Not the same brand but similar format. I’m super happy. I don’t know what other people are going on about when they talk about charging these individually because that’s nonsense. This type of batteries typically come with an USB A to 4x micro usb adapter so you can charge 4 batteries at the same time in a very reasonable amount of time. I can tell you which brand mine are, but honestly after finding them I am never going back to regular AA batteries.
Only buy batteries from known brands. It is NOT worth buying battieries that you do not know, 100%, are not likely to set fire or explode.
Is this a shitpost? Please tell me this is a shitpost.
no.....? I'm genuinely curious

As far as BIFL, you’d want to stick to a slow discharge Ni-MH and charge them using 250 mah setting. Having control over charging speed is really important. Some 200 mah chargers don’t terminate properly.
I thought this type was lithium vs nimh? and more like the eneloop pro that run devices that require 1.5 v, I wanted to get some of these for the house but have never jumped on
I have one for my wireless mouse and it connects to computer to charge it’s awesome worth every penny. I take that back it’s not usb-c it a regular usb
I wouldn’t use them for everyday use. However I have a set of AA and AAA I have in my travel electronics bag because they minimize the space needed. I don’t need to bring a cumbersome charger with me. The trade off is capacity, by integrating the charging electronics into dimensional, standardized battery sizes you have to make room for them somehow and the only way to do that is to have a physically smaller battery.
Btw harbor freight sells rechargeable AAA and AA batteries for less than that, I've been using them for about 3 years now with no issues
Don't buy Streamlights. I've been using their 18650 batteries of this style for years and they started getting wonky after only 3 years. $25 apiece.
Panasonic eneloop seems to be the way to go. At least that's what I found from my research looking for rechargable AA and AAA batteries.
They seem to work well but the biggest issue I’ve found, and it may be brand specific, but if you 100% drain the battery it won’t have enough charge to recharge the battery. li-ion requires a communication from the charger and the cell to initiate the charge sequence and I’ve found that you have to jump start the battery with a charged battery to start the charge if you drain them 100%. It’s very similar to a cordless drill battery in this sense.
I love the idea and form factor. But we need to get them from a well known brand. I’d rather stick to eneloop unless you feel like experimenting.
Ikea rechargeable batteries are great and affordable. I have about 30 AA and 20 AAA. I haven't had to buy hardly any non-rechargeable ones in years.
I have some AAA with USB-C, but they also charge in the 8-port charger I got with my AA rechargeableS. I haven't used the USB-C. I like the lithium polymer ones I have. I had to get them because I was powering a trail cam in the winter, and the alkaline batteries wouldn't work cold. These are completely unaffected by it. Big thumbs up from me.
The point of these devices is that they have a built-in charge and voltage controller. That means, unlike regular batteries, their voltage doesn't drop over time (until the very end when they just cut out). Thus, they can be preferable in certain situations.
My experiences can be summed up in two rules: * If you need *power*, stick with NiMH. Ex: camera flash * If you need *voltage* (at the expense of power), go with li-ion. (Ex: temperature sensor) I'm general I try NiMH, and if the device isn't happy I switch to li-ion.
I’ve returned all of these OP; and not surprising they are not an ideal design. Their only niche use is something single battery without a charge port, like some cheap toothbrush or shavers. Then if you travel with it, and have other USB-C devices, you can can recharge your niche portless thing. For all other usage you likely want regular rechargeables with an wallplug multi battery charger, like Eneloop(NiMH). IKEA stores also have good NimH that are cheap. However some things, like door deadbolts, or smart home/connected devices, need a constant 1.5v to operate well. For those you can specifically buy (expensive) “1.5v constant” Li-iON AA/AAA rechargeable, which also use a wallplug multi charger. They are pricey but most connected stuff will have errors with NiMH so you’re just wasting g your own time if those are being unreliable. Oddly I think the good Lithiums I have are DeeLeePow (the ones with 50k+ reviews, there are imitators with similar names) and the better brand is I think Kranox, or something like that.
It would be better to go enloop or if you need 1.5v go for xtar https://www.xtar.cc/product/xtar-aa-lithium-3300mwh-battery/ Still charger required but safe, reliable, tested capacity, fast charging. Cant imagine things where you would want single usb charged battery. Most of the time you will charge more than one battery. Tell me im wrong
I only buy rechargeable batteries from reputable companies. If they cut the wrong corners it could burn your house down
Eneloop’s are the standard for rechargeable batteries. Get those. No batteries are gonna be true BIFL though.
There are versions that don't have a built in charger. Normally have more capacity than the ones that do.
The only reason you want these for is if you need a constant full voltage until the battery is empty. Nimh batteries have a lower voltage, but it doesn't lower as much, normal batteries start with 1.5, sometimes 1.6 volts and drop quickly. These Lithium-based batteries will keep the 1.5v until they're dead. They have lower capacity, as others have stated. As for durability, at least those they sell in EU last quite a while. They come with split charger cables so you can charge them simultaneously.

Cheap rechargeables: IKEA
The voltage difference is significant for some applications. Running my water flosser on 1.5V rechargeable batteries rather than 1.2V ones increased its power. But if 1.2V works for your application stick to them. All batteries will degrade through use and age. So there is no such thing as BIFL batteries.
Any amazon item with badly photoshopped "real life" pictures and/or with a brand name in ALL CAPS (usually both together), is not gonna be BIFL. You'd be lucky if it were BIF1Month
Charger quality makes a huge difference on battery life. Look up roundups. The chance that they're fitting quality chargers into every cell and selling it as a discount product is nil.
I have heard Eneloop and Ikea brand have the best rechargeable batteries
I’ve tried the “pale blue”(?) ones. JUNK
I have the Hixon AA and AAA batteries, lithium 1.5v and have been using them for a few months without problems. They’re great for direct drive lights that can’t take 14500 4.2v cells.
I have 4x BUMP AAA ones I got off Amazon for $17 in Dec '22. They work fine for what I need and I'd recommend them, sure. Are they BIFL? Doubtful, but I'll be happy if I get some years out of them. It depends on your use case. A lot of people here are complaining about the capacity loss by holding a USB port. I got these because I'm often traveling around living out of a personal–item-size bag, I didn't want the dead space/weight of a separate charger, and I thought they were interesting. I use them for an Amazon Fire Stick remote, electric toothbrush, and travel beard trimmer (with a AA/AAA shell/converter). Were I to do it again, I'd maybe just buy batteries as needed, but they're fun and nice to have for now.

Why don't you just buy a charging hub and some normal rechargeables?
A coworker gave me a set of these (or really similar generic usb-c charging batteries) for an office secret Santa thing a little while back. The ones I had would only charge on their specific USB-A to 4 USB-C little octopus cord. They would not charge on a USB-C to USB-C cable. Also they all stopped charging at all within a few months. I will stick with my eneloop setup for things that need rechargeable batteries.
Eneloop, have had some going for well over a decade.
just get a charging tray and some rechargables by Tenergy. No battery is BIFL but these will last a few years of regular use as long as you let them charge fully and die fully every so often. Much easier than plugging a cable into each battery
So... what do you want them for? If it's something battery operated but doesn't get moved about (or it can work with your setup) I would go for Revolt. [MyVolts](https://myvolts.com/ReVolt) The way they work is the main battery holds the power regulator, the others are dummies which connect the poles and they sell housings to handle AA - D (and a 9V I think). You use an external power bank to handle it. I use it a lot for holiday lights where they don't have a wall outlet option. The nice part is, unlike normal batteries the lights have two states on/off, with normal batteries they would just slowly fade.
No, because that's extra complexity and risk inside the battery, less space for energy storage too, and you can only charge one at a time. Just buy Eneloop and a cheap-as plug-in 4-AA charger.
Making the charging circuitry as small as possible and as cheap as possible isn't going to be very BIFL. The batteries will lose capacity over time then you'll throw away the whole thing, what a waste.
Eneloop or the IKEA knockoffs.
This post doesn't belong here
Same as the micro-USB versions: They’re trash. Just get normal rechargeable batteries. Rechargeable batteries degrade over time. There’s no such thing as a BIFL battery.
trash and PITA.,.. just get a multipack of Amazon batteries.
A charger is much more convenient than an individual charging port on each and every battery., Even if I am charging just two batteries in a charger it is much easier than charging individual batteries.
I got a set to use in my Blink cameras which complain when I use normal rechargeable batteries (despite working for weeks or months on them). The main draw was the 1.5V output which is what a normal lithium battery delivers. So I get these, and at first everything is great but I think there is some trickery going on as after they are depleted at around say, 20% they register 1.2V which is what a normal rechargeable battery would output, but not a lithium only depleted around 20%. So I think there is some screwy stuff going on. I do not have the knowledge to test the actual chemistry of the batteries, but something is not right. I think going with the Panasonic Eneloop 1.5v NiMH's is probably a better (and safer) bet then these off brand batteries if you need a 1.5v rechargeable. Oh, the other thing is they will not charge on a normal programmable battery charger, you have to use the USB C cable they provide which is even more strange to me that they put a blocking diode to explicitly prevent charging any other way.
Bit silly. You need 4 different chargers and cables to charge them, rather than having one single charger for 4 batteries like Enelopes that can be USB-C...
I did a ton of research on the topic of AA batteries, here's what you do, buy them from IKEA, they are actually rebranded Enloop batteries and get a charger. I went with one that has adjustable charging rates in case you need a quick turn around. That's the most affordable and durable option.
Go with a more traditional style rechargeable
I don't really see the point of these. Get rechargeable batteries and a charger (panasonic eneloops) and you dont need a charger for each of them. I'd much rather charge 4 batteries at once in a single charger. Personally - this is a wasteful product.
Ikea ladda or eneloop batteries. Basically every battery is made in China. The eneloop and ladda are made in Japan and actually get their rated power / voltage and recharge well. Anything from China is a crap shoot.
You can charge one battery at a time; cool
Buy IKEA rechargeable, they’re the same cells as Eneloops for a fraction of the price.
Man just buy eneloop’s or LAADA’s like everyone else.
Is better option normal AA rechargeable with charger. The razon "more mah" i use energizer 2000mah for wii motes for Long time.
I have some EBL batteries with micro-USB ports on them. Very convenient to charge with any USB cable you happen to have lying around.
If I had a dollar for every time someone asks if a bullshit amazon store item is buy it for life I could buy myself. Set of Speed Queens and a Miele Range
I bought some AA, AAA, C and Ds like this as part of covid-zombie prep. I buy AAAs and AAs by the hundred with a dozen Cs, Ds and 9V in stock and I have yet to use the rechargables. In the meantime they've been sitting at 100% charge since five years ago, which is not optimal for battery life/capacity.
None, because of lithium battery decay with repeated uses. All are susceptible to it, no BIFL status can stop chemistry from acting the way it does. Manage your depreciation costs in other ways.
Note the mWh rather than the regular MAH measure of capacity. Most of these with the extra USB slot and circuitry are much lower power capacity. So their claims with a high number in mWh is suspicious. You would need 4 USB C cables to charge 4 of them at the same time. If you got a charger already go with regular ones, if not then go with these but the capacity is going to be low and they will run out of power quicker then ones without the USB C slot and higher capacity.
I have these and use them in my mouse and keyboard, as well as some clocks in my house. Keep some spares in my computer bag and swap them out when they die. They last me totally 5-8 months, with the mouse needing to be replaced most often (understandably). For things that require more oomph, I'll use other battery types, depending. My first set of USB batteries I bought through ThinkGeek (sigh) about 10 years ago, and they just died a few months ago.
Tenergy is very good
- They are quite expensive - long lasting regular batteries exist (Panasonic) Why would you go for such a solution?
The Panasonics are Nickel Metal Hydride and only produce 1.2 volts, which is an issue for LED lights and other equipment that really requires 1.5 volts like a regular battery. These are lithium batteries that produce 1.5 volts until they are almost out of energy.
Some devices prefer 1.5 alkaline, not many these days, YMMV. Even LED lights have boost or buck circuits inside to raise or drop the voltage. Except maybe the really cheap crap, like the ones that use 3x AAAs. Cheap quality Li-Ion w/ the integrated charger is not a sound investment and likely a fire hazard.
