I also had a similar problem. You will definately want to change out the negative cable. I bet it has interior corrosion also. be sure that you have the engine ground strap on and it has a good clean surface to ground to. I went through 4 batteries in 3 years before I got my problem fixed. The battery could have a dead cell. it can be tested at any local parts store. but I would change the negative cable and also make sure your engine is grounded to the frame. Sometimes the straps will break or not get a good ground. It will drain the hell out of that battery and eventually kill it.
