Battery Contact Corrosion
Battery Contact Corrosion
(OP)
I am having problems with AA batteries and the contacts to the battery terminal in a battery pack. The battery pack will hold 6 batteries. It appears that a green patina forms on the contacts in the holder. It does not look like the batteries are leaking. Is this a unique phenomena or should I be concerned. I have several thousand instruments with this battery pack installed.

A trick I've used is to coat the system with sodium silicate, "egg saver" we farm kids use to call it, to inhibit the corrosion.
