I have always read that using an eraser on the battery contacts will help but I tried this on my pack that I can open which is the one I use the most and it still conks out after a few minutes. Does it get to a point where it has to replaced, in other words buy a new battery pack? I tried the one that came with the MD and that one works fine so I know it is not the contacts inside the handle but the pack itself that is the problem. Any input would be appreciated.
