Voltage regulation on GE charger.   It's all academic, as the design of
the charger incorporates a timer and the timer is supposed to shut it
off, prevent battery overcharge, not the regulation of the charger.  Note
all the hue and cry in the instruction book about how to set the timer
for aged batteries.
