Hi Patrick and ville,

I finished writing up the battery issue and taking pictures. You can see it here:

Short Circuiting Battery Problem

I tried to come up with as simple a solution as possible for fixing it, and just rubbing the contacts with a steel tool with some pressure fixed it on my sample meters here. I even used a fork on one contact as a test and that seemed to work.

Thank you for helping to document the problem, and sorry for the trouble. Best
