melasta 16 Count NiZn AA Rechargeable Batteries 2600mWh, 1.6V AA Battery for Outdoor Solar Light Flash Mouse Camera Toys MP3

Out of the first six batteries I put to use, one was clearly a dud. You could charge it, but it would discharge fast and cause the whole pack to misbehave even with 93% charge remaining. I realize duds are a possibility, but it's pretty disappointing.Edit 10/26/2019 - The seller kindly and promptly offered a partial refund for the bad battery. I'd prefer stricter quality control from the factory, but I really appreciate the sincere effort to make me happy. I've added another star.

These have not been a good purchase. They don't hold a charge for long at all. Not worth the money.

Every one should know and use these over NiCad or NiM, they are true 1.6v and last almost as long as a regular dry cell battery. Only problem is you need a special Ni-Zn charger.

I use these batteries in RC transmitters. Which some of my transmitters like the Futaba 4px has a LCD display, which drains regular NIMH rechargeable batteries quickly. But not these nizn, they are awesome. They last twice as long as competitors NIMH.

out of the 16 batteries only 2 now work. And about 6 only hold a charge for 30 mins. They are cheap and its hit or miss if they will work very long. Do your self a favor and spend a little more and get real batteries

Worth every penny, best battery out there period and its rechargeable!! Charges fast, comes with plastic organizer case.

Easily charged and hold charges well.

These batteries didn't survive more that 2 charges on a nizn charger. All of them are dead and it was a waste
