Fast charging for NiCd should stop when the terminal voltage peaks then
declines. For NiMH, charging should stop when this voltage peaks. The
better chargers will also monitor battery temperature. Although NiMH cells
tend to lose charge faster, the higher capacity and lack of 'memory' effect

UL, 'memory effect' in NiCds is very, very unlikely to occur in normal
domestic use. It occurs when NiCd cells are recharged by exactly the
same amount at exactly the same interval several hundred times.

Dead (or dying) NiCd cells supposedly caused by memory effect have
just about always been killed by overcharging.
