Thanks Frank for the excellent description. I wanted to complete it with
following:
A) The connection between 2) Minus and 3) Thermistor is essential. I it is
not there the Newton doesn't recognize the accu as accu.
B) Shorting the thermistor terminals makes the Newton thinking its accu has
64 deg C and stop charging. I use this in the latest generation of the
battery tray modification to tell the Newton if alkalines are inserted in
the tray (see http://slsbd.psi.ch/~mmailand/Npages/Naccu/Naccu.html
including schematics of the accu)
