HP 33E Questions Message #1 Posted by Ciryl E. Negmonte on 20 July 1999, 8:48 p.m. Hey, I have an HP33E I have been using since I bought it new in college (1979). Anyway, the battery pack wore out a few years ago, and I have been using 2 AA cells, with a piece of metal jammed in the back to complete the circuit. Will I hurt it if I continue to use this power source? Thanks, cireneG

Negmonte on 21 July 1999, 7:05 p.m., in response to message #2 by DaveC Probably because I had a pair of AA alkalines in hand when I thought of putting them in the calculator. Also I have an almost inexhaustable supply of them, because we buy a lot of TV monitors at work, and never use the remote controls. Most come with a pair of AA cells. Do you suppose the native charger will work on NiCads he asks realizing it is a really stupid question. Thanks, If I ever get a set of NiCads, I will do it. Thanks, cireneG

On the other hand - if you plug the charger in with dry cells in the machine the results *could* be interesting.
