RE: HP 41C series battery issues
IIRC HP-41C includes a diode in the CPU board to prevent damage to circuits due to errors in battery polarity. It is a Schottky diode, whose forward voltage drop is less than the forward voltage drop of an ordinary silicon diode, a not-so-usual and nice engineering detail.
