The whole issue on the battery contact is the pins are only going into the female using a 1/16th of an inch or less contact. Look at those pics, pins should go in at least a 1/2in to make a quality contact. I've never seen pins that contact so little in all my life. That's the friggen issue, period!Yea I think this is still usable with your first suggestion. Looking at the wear it's appears that only the tip touches which seems really odd. It's got me thinking if the male pins got pushed in?

Taking out in the inner o-ring wasn't quite the fix for me. I notice that I do have excessive play now & some of that is due to the wearing of where the bolt locks into the battery. For now I've put a couple pieces of tape in there to make the hole smaller so it pulls the battery in more. Hopefully it holds up.
