Panasoniceneloop AA and AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries Bundle (12 Pack of Each)

perfect

The best rechargeable batteries in their class. The only drawback is heir price. However, they are worth it compared to other rechargeable batteries.

I've switched all of our battery operated devices to these. A LOT of devices

Eveloop has the best recharge batteries. other brand of rechargeable seem to get a "memory" and not have a good voltage after a few recharges. i never seem to have a problem with eveloop. they are made in japan with a great QA process. They say that they have a 1,500-cycle recharging but I'm way behind that, the ones i got back in 2010 (second gen) are still going strong.

These batteries last for years. Now that I am a frequent flyer with them, when I order a new batch, I mark them with a magic marker on the year I got them eventually they do Peter out but it’s years later.

We love our envelop rechargeable batteries! It saves us from having to go to the store to buy more batteries when the originals run out!

As a musician using a wireless transmitter that uses 2 AA, I just swap the batteries for fresh ones after every set, and have NEVER had the batteries run out of juice.I've still use the same 4 AA that I bought in 2015(!).

They work as expected, no complaints so far.
