I think no chance to repair those relays even after you torn one open.

One should never handle watch/memory batteries with bare hands.  The oils and salts in a fingerprint across the cell can discharge the battery faster than the circuit.  I also always clean my cells with IPA before installing.

I think Hugoneus confused a little pinout on relay when talking about it. Coil drive pins are on same side as center "RF input" contact

Nice video, I add vote comment to see video on how to simulate RF components in software. Are there any "hobby"-level RF field simulators? .

I think you might be right about the pins. I was traumatized about my tool breaking. 

Haven't found a good hobby 2.5/3D simulator yet.
