HP 41CX replacement battery foil


I have recently bought a 41cx to accompany my beloved 71b :-)

I use a circuit simulator at work with an RPN calculator and decided that I needed the real thing.

Unfortunately (you guessed it) the battery compartment is corroded.

I know I should have checked but I was guilty of a rush of eBay blood.

One of the forum members used to make (or have made) replacement foils

Does anybody know if they are still available ?

Many thanks in advance3
