Energizer Rechargeable AA Batteries (4 Pack), Double A Batteries

These batteries work surprisingly great! I don't use them any gaming devices since most of them have built-in batteries but they're good for accessories or even high-drain devices that you don't wanna have to buy new batteries for every two weeks. Power level thus far has stayed excellent. Charging takes about 8 hours or so, just leave them in overnight and you should be good to go. Performance wise these have no issues. We also ended up getting the battery charger and some more batteries. They will cost you a bit more but they're definitely worth the price.

These batteries are made in Japan. My experience with other made in Japan rechargeable batteries is that Japan made batteries have a longer service life than batteries made in other countries. Japan batteries cost more than batteries made in China, but have a longer lifespan than Chinese made batteries. I prefer Nickel metal hydride batteries to lithium batteries because I'm not aware that a NiMH battery ever caught fire. Lithium batteries usually have more capacity than NiMH batteries, but definitely are more dangerous because they can catch fire even when not being charged.
