I loved these batteries when I first started buying them. They were cheap and seemed to last. Then I bought 48! I figured - cheaper by the (4) dozen - Big mistake! Not only don't they hold a charge in a device, they are actually dead coming out of the shrink wrap. I actually had a couple literally fall apart in a camera. Luckily there was no damage. I expect high quality from Amazon basic products - they usually are great - but these batteries are terrible!.
