I just fried two HP-41s?
Yesterday my 41CL just stopped working while I was using it. So I recharged the battery and let it sit overnight. I tried to insert the battery again and no go.

Today I took a new 41CX and swapped batteries between them. It did not help and the 41CX made a single BEEP at power on and now it is dead too.

Now I wondered if the NiMH cells turned bad and is outputting too much voltage so I took out my old multimeter, but it does does not work either, just random readings, so I cannot even measure the batteries.

Very frustrating experience and I need to use my Ladybug to do some debugging on the computer. I guess I need to power up an HP-16C instead.
