See, now this is why I shouldn't do hardware Message #1 Posted by D. Banks on 12 Mar 2001, 10:06 a.m. Recently rebuilt a 3x series battery pack. Radio Shack sure does make this easy: I got a gang of 5 AA NiCds and clipped two off - already soldered together in series and everything. Tried the battery pack in a bunch of the collection. Why is it that any battery pack fits so tightly in the 3x series? Always seems like it takes a lot of coaxing to get the thing out. When removing the pack from a 38E, one of the battery contacts came out with it. Tried soldering it back in place and trying again. This time the other contact came out. Never did see the calc power up. I fear I've broken a 38E. Suggestions?

Banks A very LONG time ago when my daily calculator was an HP-32, I broke off one of the contacts. A small piece of aluminum foil folded into a short strip and wedged between the battery and the remains of the contact solved the problem. Bit of a kludge but it did the job!

Re: See, now this is why I shouldn't do hardware Message #3 Posted by Andre' Wilhelmus on 13 Mar 2001, 4:10 a.m., in response to message #2 by Jerry Doctor My HP-37 broke off both contacts. To see it work, I put two long screws with a nut in the compartment between the remaining battery contacts and the wall on the opposite site. Then I took two wires with two clips each and clipped those on the screws and a separate battery holder. The clips have plastic around them to reduce the risk of shorting the batteries.
