What's the capacity of your batteries? I realize the Canon ones are not as high volume, but from what I know the genuine batteries will last much longer. My rebel batteries after two years still works like new, however, one of my friends using a 40D declares thathis 3rd party batteries lasted for a good year then the performance noticeably dropped, is that true?
