eCost(16) Acuvar High Capacity AA Rechargeable Batteries 3100mAh NiMH, Precharged

Great Batteries!!,... Only thing to watch for is that while the description says "Can be charged in most AA chargers | Memory Free" and that statement is TRUE, MOST chargers will not charge the battery to the full 3100 mAh usually halting at around 2400 mAh (IIRC).

I use these primarily for wireless mics and body packs, usually draining and recharging a few times a week. So far so good, after a few dozen cycles, I still get about 6-8 hours of continuous use out of a full charge which is right inline with non-rechargable alkalines. The prices aright too, so it's likely I'll be back for more.

great batteries - we use about 60 of them for music groups - - they've saved us a ton of money!

I have used these for years now and they continue to live up to expectations.

This is my second purchase of these batteries. I use them in many appliances around the house, and in outdoor solar lighting. Once charged, they will last a long time.

Terrible batteries. I bought these batteries hoping they would at least last as long as a typical non rechargeable battery. but nope, these last less than half as long as RAYOVAK's batteries. Waste of money.

These batteries are bad. They hold only fraction of the claimed charge. It takes long time to charge them and very short time to drain them. Waste of money.

It may be because they are new but these outperform the batteries that I bought a couple of years ago.
