41CX Battery Corrosion
I rediscovered my old rechargeable 41CX yeah, but the rechargeable battery and the contacts are severely corroded (boo). Any suggestions on how or where to get it repaired? I live in houston and realize most likely will have to ship but need a reputable place.

And another yeah, I just found an old 41 CV that appeears in great shappe, Need to order batteries so we will see if the $4.50 fix works on this one.

Thanks in advance and great forum, just joined.

Great that you fond your old devices!
The rechargeable battery can be rebuild with new cells, which is not THAT hard - i did it here, for example:

If the foil contacts inside the calculator are corroded too, there are replaceable foils for that here:

Alternatively the contacts can be fixed to a working state with a bit of wire.
