Did you realize that there are two different battery packs for the HP-41? One has 2 charging pins, the other has 3 pins. Both are coded HP82120A.
I'm currious as the charger for this unit has only 2 pins... the middle pin of the 3 pin version is absolutly "useless".

Hello Matthias,
You can find the information on the HP82120A with two pins

Of course we
know, Matthias.
My first one was a 3-pins design.
