3Place the battery in the recharger as shown.
Recharging begins immediately. You can remove a battery from the recharger
at any time. Remember, if you are charging two batteries, they charge one at a
time. It takes about two hours to charge each battery.
IMPORTANT
To preserve a battery’s charge, don’t leave it in the recharger if the
power adapter is not plugged into an electrical outlet.
The lights on the recharger indicate the following:
m
No light
Either the recharger is not plugged in, the other battery is being
charged (if you have two batteries in the recharger), or the battery is
defective. (If the light goes off during recharging, there is a problem with
the battery.)
m
Yellow
The battery is charging.
m
Green
The battery is fully charged.
m
Red
The charge does not recognize the type of battery inserted. If you are
charging a replacement battery, follow the instructions that came with it.
Recharging in both the computer and a recharger
You can use a single power adapter to run the PowerBook Duo and the
battery recharger at the same time.
If the PowerBook is on and contains a battery that is not fully charged, the
computer charges the internal battery first. The external battery does not
begin charging until the internal battery is fully charged. If you are still using
the computer at that point, it takes a little over 2 hours for a fully depleted
external battery to charge.
