I got this TI-83 calculator for free (didn't work). But I found the issue. The battery contact pad on the right looks fine, aside from a little material missing. But the pad on the left looks awful...corroded as well as missing material. How best to repair this? I have some copper clad board. If I can remove a piece of the copper foil, could I reasonably expect to get the glue side clean and can I reasonably expect to solder it to the bad pad? I also have brass shim stock (0.001").
