Hi Guys, I am in the market for a couple of replacement batteries for my aging Canon 5D original. BP 511A
Looked them up on the net and the prices range from $160.00

to only $17.00
So do you reckon i need to go mid range to get something that will a least hold a charge, or would the cheapies be OK as well
Anyone had experiences with this sort of thing.
Thanks in advance.
Leon
