cheaper batteries for the HP41CX
Posted by Michael Harwood on 30 Jan 2009, 9:32 p.m.
I found that the J size battery is a flat 6V battery and will fit into your HP-41CX. It is only $3.00 (in Canada) and a lot easier to find. It took a bit of fiddling with wires to get the + and - to the HP contacts, but now it works. I can upload a photo if anyone is interested to see how I did it. * Note: I had an extra battery holder which I used after I removed the dividing sections for the N batteries.
