I've read the same thing Bob. But even though it's not true "memory", a battery still improves in internal resistance and capacity by cycling it a few times if it's been dormant for awhile. I used to fly electric R/C planes, and the amount of power available is very noticable. You can tell when a battery isn't performing very well quite easily, either you don't get the climb performance you're used to, or your flight time is cut short.
