Bought these to go with a new digital camera. They arrived nearly dead; they would fire up my old camera almost through the boot. So, I decided to charge them. Installing them in the charger, as directed, showed them charging (red LED to green) in about 10 seconds. \But, they still wouldn't boot the camera. So, after some effort, I found that if you spin the just right batteries in the charger, they will switch from green back to red and charge. So, after about 5 hours charging the light switched to green. Yeah!Now, I plug them in and they seem to work...until the third picture. Then the low battery warning comes on. These are not worth the trouble. Buy a name brand.
