Only in being compared to NiCd. Ni-cads were/are pretty attrocious in heavy
use cycles and NiMH can recover from memory effects far better than NiCd. It's
not really anything you have to be worring about on a day to day basis though.
It takes alot of cycles to build up a memory effect (purely a guess, I'd say
20-30).
Case in point, salesman X uses his laptop for work every day in city H at
office F. Most of the time he sits at his desk E, plugged in, keeping his
NiMH/NiCd battery N fully charged. At 2:30pm, he unplugs and wanders down to
the staff meeting in room G to receive his daily
belittlement...err...ahh...employee encouragement. Being as it is always
boring, salesman X, like most of the others fortunate enough, whips out the
laptop and plays Quake and solitare for 40 minutes. Then he wanders back up to
his office F and plugs in again.
Then one Monday morning, salesman X finds out he has to fly out on plane Y to
give a presentation A to company president Z because manager Q chickened out
and made up an excuse about having to stay and dish out the daily
belittlement...err...ahh...employee encouragement to keep the L office working.
Not only that, but the presentation isn't even close to being done. So salesman
X hurried packs up and takes a taxi O to airport R to catch airplane Y to see
the president Z in T. He figures he'll finish the report en route. Fourty five
minutes later salesman's X laptop dies, thoughly corrupting the disk in which
presentation A was saved. Presentation A is ruined, infuriating President Z who
fires manager Q, throwing office F into a raging turmoil, who burn salesman X
in efigy on desk E in room G, the result of which is greatly reduced travel,
causing airline Y tp pull out of airport R bankrupting city H.
Imagine that, destroying the lives of hundreds of thousands of citizens, if
not millions, all because you wouldn't cycle the battery N or get a battery L.
OK, that was a horrible waste of bits...but I had a train of thought going
and I wanted to stick around and watch the wreck.
