This is a 1900mAh high capacity replacement battery. It is compatible with EasyShare Z1012 IS, Z1015 IS, Z1085 IS, Z612, Z712, Z812 IS, Z8612 IS, Z885. I bought it from Amazon and had been using it for my Kodak z8612is. Besides that, i also purchased insten battery charger to use with the batteries. The charger charge the battery in just 4 hours. The indicator light will turn off to indicate the battery is ready.
It is best to let the charger lying down while charging. This can ensure the battery stays in the slot due to some battery casing size is smaller (as claimed by other user)
This is the KLIC-8000 battery i got. The build looks solid and quality. The spec is 3.7V/Li-ion, 1900mAh. It took me about 4 hours to charge it up with the insten charger. Trying it on my kodak z8612is, the camera still don't show low battery warning even after 400 pictures taken. (about 100 pictures with flash). It is definitely worth the money.
