AA Rechargeable Batteries Micro USB Ni-MH Universal eco-Friendly 1000x Rechargeable Micro-USB Rechargeable Battery 4 Pieces pre-Charged

I really like these batteries. Some years ago I found these exact batteries at a local store and immediately bought them because it was the first time I had ever seen rechargeable batteries that were recharged by a USB cable opposed to being placed in a battery holder type device. It was 2015 when I bought those packs, one pack of AA and one AAA. I still have all 8 batteries. They’re still working well, charging well, and overall just perfect for what I use them for. So with that being said; since it’s now 2020 and my son is now 8 years old and seems to need batteries every time I turn around; I found it’s time to buy more! I searched Amazon for recharables and there are SO many choices that honestly it’s a little overwhelming. I decided why not stick with a battery that I know for a fact has worked well for five years, so that’s how and why I ended up purchasing these specific batteries. We’re on week two or three with this package of batteries and admittedly these newer ones do charge up a bit faster than the ones I bought in 2015, but the difference isn’t so astronomical that I’d toss out my old ones or bash my old set. I love all 12 of my EcoJuice batteries!!I don’t know how these batteries “store” over time. I can’t speak on that because these are the batteries my family uses for things to avoid purchasing so many disposable batteries. I don’t put these batteries in TV remotes or anything that uses small amounts over time. I mainly use these in my outdated bug zapper racket to kill the moths on my porch. Flash lights. I also use them for a small fan that’s supposed to be interchangeable batttery/USB. However, that fan fell into water and will now only run via batteries. When I use the batteries for these types of devices I get roughly 3-4 hours of usage out of them. We charge them and reuse them often. My son uses them for his xbox remote and he gets about 5 hours of use time.

I use these batteries a lot. It is so convenient to plug in just the battery and not some big recharging station. Got the AA's liked them so much I also bought the AAA's.

I bought these specifically for a CD player that eats batteries like crazy, they don't work in it. I don't know why. They fit fine, are fully charged, but the player acts like there's no batteries when I put them in.I haven't tried them in anything else.

Even after being charged. Did not work. It sucks I need to pay for returning them!

I am disappointed in these batteries. They don’t seem to charge up all the way and they run down way too fast. They go flat in my trail cam in less than 8 hours and after 6 complete charge/discharge cycles there is no improvement in their charge duration. There seems to be a lot of positive reviews for them but I am not feeling that love and I cannot recommend them. One star for being at least the proper size and fitting everywhere a AA battery should and one star for charging up fast, albeit not completely.

They're a great idea, and we really need to recycle and use stuff longer, but the truth is, I would like to get more than 35 days of juice.

Excellent batteries! These things last for a much longer time than standard alkaline and lithium batteries. Normal rechargeable batteries can't hold a candle to these, these things are awesome!
