I just got a Minolta 7000i and I cannot find how to replace battery. instructions say on bottom of camera on right hand side there is a compartment that opens with a coin. On my camera in that area there is a rubber pad but no compartment. If I pull rubber pad off, there is no compartment under it. I truly cant see how to replace battery and feel very stupid. I am also wondering if there is an internal lithium battery I need to replace also. I would like to get this camera going. please any ideas?
