Re: HP-41 bat holder Message #1 Posted by David Smith on 12 Dec 2002, 5:37 p.m. Battery holders have become just about impossible to find. Your best bet is to find a dead calculator with one on Ebay. Expect to pay over $40 for a dead, corroded, HP41C... make sure the battery holder springs have not disolved. Occasionally you find the rechargeable battery packs for sale on Ebay... for big bucks. You might want to avoid them if they have not been rebuilt with new cells. The proper cells are no longer made and are pretty much impossible to find also. With a little shimming, etc you can rebuild them with nickle metal hydride cells or 1/3AAA NiCad cells.

NB This is not recomended for anyone who wants their battery pack to look "as new" :-)
