I've got a Canon EOS camera that takes a BP-511 battery. The specs on the battery are 7.4V and 1100mAh. The battery is dead and I want to buy a replacement, but I'm looking at a third party battery, because it's much cheaper than the Canon branded one. I've found one with very high reviews online, and it seems identical except that it's rated at 1500mAh instead of 1100mAh.
So the question is: is this difference important to the camera or not?
