This was actually in the help file for a Li-Ion battery, which was a
surprise to me, although perhaps the file is for NiMH too.  I don't think
IBM has NiCd laptop batteries anymore.

This was out of the help files for my T21.  Somewhere off on the web (I
didn't try to find it again), they have a much more thorough discussion of
the differences between the care and feeding of NiMH vs Li-Ion.

In their procedure for cycling the battery they have different procedures
for Li-Ion and NiMH.  However, in reading through them, I suspect that the
difference is mostly around how much intelligence they have built into the
battery.  I get the impression their NiMH batteries know how to cycle
themselves.
