Hi Paul,

thanks for sharing this information.

I checked the scan of the hp 75 user manual on my hpmuseum DVD, and on p. 272 it says "The nickel-cadmium rechargeable battery pack uses the two parallel contacts in the battery compartment" which supports your statement. Additionally, the photo shows the third contact far to the right of the other two.

I just soldered the contacts to the stubs, inserted a refurbished "classic" battery pack - works :-)

Yours, Helmut
