Battery options for 82143A printer

[mfleming]

I like the approach Hans-Peter suggests, because once built you can recharge the pack without opening it. Your idea corresponds to what I did with a Classic pack rebuild. I used 3 AAs with copper strips to bridge between batteries and the the original contact strips to bring out power. Everything was snug enough within the battery case that pressure kept the batteries in good electrical contact with the metal parts. I could recharge within the calculator, or disassemble and recharge the batteries separately.

If you give it a try with subCs be sure to mark where everything goes. Easy to reassemble in reverse order and get the wrong polarity at the contacts!
