24-Count Amazon Basics 2000mAh AA Rechargeable Batteries

Upon closer inspection, the country of origin changes, depending on which quantity you buy.

I'm seeing China listed on everyone. Do you see an option with Japan?

24 pack arrive, every single one charged up fine

Yes I would like to do this I have the Panasonic bq- cc55, will that charge the Amazon batteries? My plan is to use the Amazon batteries and things like clocks and devices that don't use a battery except for backup, and use the eneloop. ( both sides can bring the hate I just want to know if it's possible).

I do not have this charger. There appears to be both a white "3 hour quick charger" and a black "4 hour quick charger" with similar model numbers - all other things being equal, I would prefer a charging current that's closer to 500ma (4 hours?) to 700ma (3 hours?) for standard capacity NiMH AAs - but all other things may not be equal. I can't imagine it not working.

They appear to currently be selling the made in Malaysia version. I've tested these, and while they're not the best quality, they seem decent and are by far the best value.





NO! Do not do this with a lithium-ion battery! Fully discharged Li-Ion batteries are an explosion risk, especially if you dump current into them. This trick should only be used on NiMH and NiCd.



If you buy Energizers, I'd suggest getting the 2000mAh version, not the 2300mAh model. In my testing there was less than 200mAh difference between them, because the 2300's underperformed and the 2000's overperformed. Also, the voltage characteristics were far better on the 2000's. They'll probably get far more service/cycle life as well.




Unless you need the little bit of extra capacity and will use it quickly, I suggest getting the lower capacity models. All else being equal, high capacity NiMH will have substantially lower service/cycle life, higher self-discharge, and they also weigh a bit more. The rated number of cycles is basically fantasy. Don't expect to get more than a small fraction, in the real world.



Don't use a dumb trickle charger. Get a smart charger and charge them at a moderate rate. I recommend ~500mA for AA and ~300mA for AAA. High rates will speed up the degradation. Charging at low rates often causes the charger to have issues detecting when the battery is full, resulting in it getting overcharged. Moderate rates likely give you the best chances of minimizing degradation.

Thanks. One more question will these be good if they fit my outdoor solar lights?

I haven't done this before, but these aren't ideal for the lights that run all night long until they die (they'd be better for switched / motion sensor lights.) You want lower capacity batteries to get more 100% daily cycles out of them - something in the 1000 mAh range. The original batteries may be NiCad.

Maybe somebody else will chime in with their suggestion, but I don't see Eneloop Lites for sale, so Tenergy and EBL would be two "brand names":

https://www.amazon.com/EBL-AA-Rec...B07DPJF1WD

Retail sales are surely a tiny drop in the bucket for the factories making these and they really shouldn't be this expensive, so I would look into more "generic" cells if I was buying a lot. If you don't care about the lights, they can recharge alkalines until they start leaking.

Edit: Looks like the EBLs I linked actually are NiCad, here are the suspiciously-rated NiMH:

Battery leaks? Too bad for you.

Go with a brand that will replace an item destroyed if it's battery leaks in it.

Have anyone tried LiFePO4 AA batteries?

Any recommended smart charger?
