UL, 'memory effect' in NiCds is very, very unlikely to occur in normal

As in a battery pack on board a satellite.


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


If it gets warm when you are charging it, you are killing the batteries.



********. I have to get my cells warm to get them ready for 3 minutes of
aerobatics.

Nicads and Nimh both get warm once past teh 'delta peak' voltage, and
deliver higher current in that state.
