Between my 2 main batteries, and 1 aux battery, I used to get over
8 total hours of laptop usage, but that's down to less than 1 hour
nowadays, as the battery life is fading.  I once invested some time
in manually fully discharging and fully recharging one battery about
5 times, and it pick up a lot of life, but again it's fading.  Used to do
that with model airplane nicads, but it apparently worked for these
Li-Ion's.

Discharging involved leaving the laptop on until it warns of battery
failure and then puts itself to sleep, then I'd re-awaken it and let
it drain some more.  At some point, it just died.  Then I would put
it back to charge fully.  Needless to say, I didn't like letting the OS
die un-gracefully.

There's got to be a better way -- is there some form of battery
cycler that I can purchase or build that will work for these (IBM
Thinkpad 600x) batteries?

Cheers,
-Neil.
