Got this beautiful HP 55 with case, charger and books off eBay. But it had no battery. I knew the terminals would be crusty, but I didn't expect one of them to completely disintegrate the moment I touched it! The calculator works fine off AC.
I'm very afraid of damaging it if I open it up to replace the broken tab - so I had an idea - take one of the batter packs I picked up on eBay and convert the terminal to a tab on the battery pack. It worked perfectly!
Hope this helps someone!

Nice find on the 55 (particularly with the manuals)! That's one of my favorites - really wanted one as a kid, but just couldn't get the money together, so I was really happy when I scored mine.

Glad you got yours working.
