I have a battery but no way to take the back off because its the screw off kind and we never had to take the battery out up until the battery died and I believe you need a certain tool for the screw off backs if anyone other than finding the tool for it has any suggestions I'm game. But I do know it works.
Will the winner get the battery also so they can have it installed? Also it looks like it needs 2 batteries, one for the analog and one to light up the dial.
