To all those who have asked about using generic BP-511's in their cameras recently and to whom I've replied that they are great and I've never had a problem:
I had one die this past weekend and refuse to take a charge (after about 7 months)
I also ordered another one which arrived yesterday and is slightly mis-shaped or slightly larger because it wouldn't come back out of my 10D. It took some work to get it out.... I trashed it immediately after removing it.
Will this stop me from buying generics in the future? Probably not. I can still buy 6 generics for the price of 1 Canon BP-511, I can afford to lose 1 or 2 now & then.
...just an update on the gen. battery issue... they aren't all as good as the Canon ones.
