I am in the process of rebuilding a 82120A battery pack for my 41CX with new NiCd cells. The problem I'm having is that the old cells leaked and damaged the metal contacts that mate with the calculator. They are both broken and I don't think they can be used again.
Does anyone have an ideas for a substitute for those metal contacts? My guess is they have to have some spring or flex in them so the battery pack can be removed, but maintain contact otherwise.
