Rechargeables can increase their voltage when discharging, I have a
discharge tester that shows voltage, current and capacity as it runs
and you often see a (small) increase in voltage at the beginning of
the discharge cycle.
If this happens, why? If has cooled down after charging, possibly the
effect of warming up a little?
