HP32SII Battery Life Message #1 Posted by Paul Johnson on 20 Sept 1999, 1:03 p.m. I have an HP32SII that drains the batteries in about 1 week, even if it's not used. Has anyone run into this type of problem? It's a nice calculator, but I can't keep investing in new batteries every week.

Re: HP32SII Battery Life Message #2 Posted by Andreas Stockburger on 22 Sept 1999, 9:08 a.m., in response to message #1 by Paul Johnson Hello Paul, I have several Pioneers in my collection. None of them has this problem! The HP42s which I have for normal usage has the same batterie-set for almost 3 years. In my opinion the built-In capacitor is damaged and as you know you cannot open your calculator ... Sorry for that answer Andreas Stockburger

Re: HP32SII Battery Life Message #3 Posted by Paul Johnson on 23 Sept 1999, 8:15 p.m., in response to message #2 by Andreas Stockburger I also have a 42S, and have no battery problems with it. I'm not familiar with the insides, but is the 'built in capacitor' for the purpose of maintaining memory while changing batteries? Next question, any idea where it might be located? The HP32S picture at this site shows the back of the circuit board. If it's near the top, I'm thinking I might be able to access and disconnect it from under the battery cover without totally disassembling it. I've already figured out a way to install a small switch to disconnect the battery without completely tearing it apart, but that would mean having erased memory every time I use it.

Re: HP32SII Battery Life Message #5 Posted by Paul Johnson on 23 Sept 1999, 7:58 p.m., in response to message #4 by DaveC No battery leaks or damage. At first I thought it might have a button presses while in my briefcase, but I left it out for the last set of batteries.
