Apple PowerBook (200 Series) - Manual (Page 61)

Reconditioning the battery
To maximize battery life, you should recondition the battery once every
30 days, using the Battery Reconditioning program, which is on the system
software disk labeled Disk Tools. You may want to keep a copy of the Battery
Reconditioning program on your hard disk so it is more convenient to use
every 30 days.
IMPORTANT It takes 2 hours to run the Battery Reconditioning program and
another 2 hours to fully charge your battery in your PowerBook. During the
time you are reconditioning your battery (and recharging it, if you don’t have
a recharger), you cannot use your PowerBook. Plan to recondition your
battery when you won’t need your PowerBook for at least 4 hours.
To recondition a battery, follow these steps:
1 Make sure your PowerBook is connected to a power source.
If you have already copied the Battery Reconditioning program to your hard
disk, skip step 2 and do step 3 next.
2 Insert Disk Tools in the floppy disk drive and turn on your PowerBook.
3 Locate the Battery Reconditioning icon and open it.
A message appears on the screen describing battery reconditioning. If you
don’t have your PowerBook plugged in, a message appears telling you to plug
it in.
