Sanyo Cadnica N-50AAA Message #1 Posted by Juergen (CH) on 26 Nov 2003, 5:01 a.m. To rebuild HP-41 accu packs, you can use Sanyo Cadnica N-50AAA cells. You can buy them in Switzerland at www.distrelec.ch for CHF 6.20 per cell. As David Smith already mentioned, they are somewhat too small, but that's no problem.

Re: Sanyo Cadnica N-50AAA Message #2 Posted by David Smith on 26 Nov 2003, 11:46 a.m., in response to message #1 by Juergen (CH) The 82120 packs already dump a fairly high charge current into the cells (15 ma). The 50 maH NiCad cells may tend to overcharge. I would use NiMH cells with a 150maH capacity.

Recommended cells? Message #3 Posted by Juergen on 26 Nov 2003, 4:09 p.m., in response to message #2 by David Smith Which type of cells do you use (brand/type)?

Re: Recommended cells? Message #4 Posted by Jim Chumbley on 27 Nov 2003, 9:07 a.m., in response to message #3 by Juergen I have always had good success with NiCad batteries made by Tadiran, an Israeli company. However, the ones I was buying were full-sized C cells and D cells. I don't have any information on "N" sized or 1/3 "AAA" cells. Can someone else confirm this information on this company?

Re: Recommended cells? Message #5 Posted by Randy Sloyer on 27 Nov 2003, 12:07 p.m., in response to message #3 by Juergen I use Gold Peak 16AAAM - 1.2 Volts, 160 mah. Rated for 16ma charge, 16 hours. Perfect match, they need some filler to take up the remaining volume in the case. 1/16" double sided foam works well to hold them in place.
