If you read up on the "memory effect" you will find that it is very
rare indeed. It only occurs when a NiCad is repeatedly charged and
discharged in *exactly* the same way (i.e. both times and levels). It
was discovered in NiCads used on satellites where the cycling was very
regular indeed.
Can happen with model aircraft - run at full pelt until the onboard
electronics cut the power at a given voltage and then are recharged
using expensive controlled chargers. Exactly the situation you describe.
But a Ni-Cad gives an extremely stable output until near flat so the
situation you describe is OK. What does harm them is to run them *totally*
flat as many feel inclined to do.
