Hi!
IIRC all the new laptops have battery life cycle counted in "number of
recharges". Some PCs have this limit set around 1000 recharges.

I've got Debian sid installed on my iBook (G3, 800Mhz).
Maybe I'm misunderstanding how power management works on the PowerPC, or
maybe something is misconfigured. It seems that the battery only lasts
for about 2 hours. I'll watch the battery drain to around 85%, and then
it drops to 0%.

I wouldn't know for sure, but depending how both batteries are connected
together, weird things could happen... although I imagine Apple's
engineers be smart enough to couple both batteries via protection diodes
preventing the lower-voltage battery discharging the higher-
pen with both batteries installed: with AC connected, at least
the big one is continously discharging a bit then recharging.

But I usually don't have to boot the iBook a lot,
