OK folks, you can see from my signature line that I have three Canon cameras. They all take the BP-511 battery.
Because I have swapped them around from time to time, and I foolishly did not mark which one originally came with which, I do not know how old they are. One of them now appears to run down very quickly, so I will discard it. Any way to tell the age of them?
I recharge them using the Canon supplied recharger.
How long a life (in years) do you people out there usually get from these batteries? One of them (from the G5) is probably 6 years old.
If I leave the camera with the ON/OFF switch in the ON position, would it run the battery down?
