I've added a remote battery to my 1982 Bally Mr. and Mrs. Pacman motherboard like ive done a few times before. It seems to work fine, but the batteries seem to drain real fast. Brand new batteries are barely lasting 2 weeks??? This is the 3rd set in a month. I checked the voltage on the batteries before they are put in, all at 1.6 volts each...with in a week, they are all at 1 volt and its gonna stop working soon.
