Never saw this coming so quick. When I put a new Rottendog CPU board in Popeye July 2017, I installed a external 3 AA external battery holder too.
Got the Factory Defaults Setting the other day when powering up Popeye. This is what happened inside the battery holder (it had a cover on the front of it held in place by a small screw).
So these batteries are barely 18 months old and it looks like this acid issue started a lot earlier.
I want to use an external coin cell arrangement instead.
Any products out there or mods for this?
