Title: Save your money. Buy the CANON battery.
Review: I've had this battery 11 months. It has seen limited use and I have alternated it with my Canon battery that came with the camera. They have both seen similar use.This battery worked great for the first 2 or 3 months. After that, it severely degraded to the point that now I can only take 10 pictures or so before it needs recharging.In contrast the Canon-supplied battery takes several hundred photos with the same charge and still retains it's charge.This battery is way to unreliable. I've lost several photo opportunities because of it. I'm tossing it and replacing it with one from Canon.
