I am new here so please be patient. I purchased a HP-41CX that doesn't work. The battery terminals are corroded and that is probably the problem. I also have a 82059D charger that is suppose to be for this unit, but I can't figure out where it plugs in. There is an opening on the right side, but no prongs. Am I missing something. Thanks for any help and a great site.

There was a rechargable battery pack available. The prongs for the pack lined up with the hole that you see. Without the rechargable pack, you'll need to clear the contacts and get some N sized batteries.

Thanks for the information. I tried cleaning the contacts and installing new batteries, but nothing.

Three free things to try:

fixthatcalc.com seems to have an outstanding reputation for fixing these. I wouldn't worry about rechargeable batteries unless you're making heavy use of the optical wand or the card reader. Without those, a set of alkaline batteries will last a couple of years.

Make sure to get 1.5V N size batteries, not 12V which will fry your HP-41.

All N's are 1.5v. It is the 12v A23 to avoid, which is almost the same dimensions.

Is it a fullnut or halfnut ?
