RE: HP12C battery contact question
It's a corrosion issue, probably due to leaked battery. You can see it on several traces and at the remaining part of the battery contact. Even a tiny spot flaked off on the plastic. I'd give it a good clean with IPA and then solder a contact replacement to the remaining plating.

I'm not sure about the construction, but if possible I would also try to remove the board from the case and clean the other side.
