The problem with, and always has been, with Ni-Cad cells is that they do
develope memory unless you discharge them fully and then recharge them. The
problem with them is that people seldom do this and indeed often leave them
on charge day after day.

LiIons on laptops which are normally plugged in often suffer - my Compaq
now has about 20 minutes life from a nominal 2 hour battery. Toshibas
don't seem so bad though. This isn't technically memory effect, but it
might as well be to most users.
