As Jan pointed out in the previous log, the solder on the battery contact pad will oxidize. If the resistance in the contact builds up too much, we can solve it by placing some metal more resistant to corrosion and oxidation, like gold on the pad.

A quick search reveals that there are SMD components which can help us out.

I'll implement Jan's idea of having a triangle of contact points.

Initially I'll just use the pads with solder, and have these as a backup :-)
