Last I've read on the subject (Frank, you correct me if I'm wrong ;-) is
that they don't have memory effect *as bad* as the NiCADs, but they can
develop some more or less serious memory effect if you always recharge them
before they're drain out. If you completely drain them every once in a
while, they would probably keep their charge longer.
