Well, first off, my NiMH experiment on the 75C is working. I'm using a rat shack 23-270 3.6V 1200mAh batteyr pack, which fits fine in the 75 once you add a bit of padding for length.
the charger does charge, though slowly, and discharge takes forever.
I've got an HPIL printer (thinkjet) and one of the cellls in the battery pac has gone kaput (it was a rebuilt pac, 6 subC cells and I imagine one of the cells just lost it in shipping)
So now, a couple questions:
is it safe to run this off of wall current through the adaptor (with batteries disconnected.)?
and- is it worth rebuilding with NiCd? I can pop down and grab a pair of 3.6V 1200-1600mAh packs and easily fit them in the case of printer.
How bad is it to run NiMH cells in the circuit if you never really unplug the machine? (i.e., if I need batteries in there to run, can I just leave them in there?)
(and yeah, I've thought about taking a few of the small 3.6 volt cell phone batteries (lithium film) in the 2Ah range and using those, but do I need the battery life?)
