Ironically, it was the conventional wisdom that a NiCad should be drained completely before recharging that often caused rather than prevented the "memory effect".

Modern technology has solved all these problems, so it is always safe to "top off" the battery.
I have to admit to not having used NiCads for a long time and not looking into them. Most of my knowledge came from the '70s and '80s with radio controlled planes and cars. I had a look when my first laptop battery died and discovered that LiIon should be treated differently. But, the rules for NiCads seemed to be the same. Since then, I've checked the LiIon info occasionally, but don't use NiCads so have never rechecked that.
