Re: The exchange of the built-in NiCd battery of HP-34C. Message #3 Posted by Karl Schneider on 26 Aug 2002, 4:37 a.m., in response to message #2 by David Smith
David --
What are you using as replacement 1.2V NiMH AA cells? I have both the "older" Spice pack (with silver metal holder and plastic spacer), and "newer" pack (2 cells in one assembly; cannot be taken apart). Both are dead.
I plan to build new packs using 1.2V NiCad AA "replace-a-cells" from Radio Shack. These are short, flat-ended, and have soldering tabs. RS does not sell similar 1.2V NiMH AA cells -- only the longer ones with posts on the + terminal, dimensionally identical to 1.5V alkaline AA cells, which break the delicate battery springs.
I agree with Mr. Rodriguez -- better to recharge these externally, even the NiCad -- and take no risks.
