Hello all! I'm new to these forums, so try to go easy on me. ;-) I have an old first-generation Canon Rebel DSLR, and every battery I own for it has been dead for a couple years now. (The charge they hold will only allow 1 or 2 shots on the Rebel.) On the back of all of them all it says "Li-ion BATTERY BP-511H 7.4V". However, every site I go to in order to find a new one shows that they only have "BP-511" and "BP-511A" batteries. Will these work with my old Rebel? The pictures of the batteries look almost identical to the ones I currently own, but I just wanted to make sure before I bought them. My second question would be this: Will my old Canon "CB-5L" charger work with these batteries? Thanks in advance, guys!
