I had two of these batteries since late October and use them on my Canon 20D and 50D. Duran (very limited use of Flash) and 1000-1400 picuters fully charged. (I use a 32 GB memory cards, and can usually last until card is full).

I can use the charger that came with my camera. What a major improvement over the original cannons. I've only had for a few months, so I can not say how good they are in a year ...
