Using additional battery packs

If you spend a lot of time traveling and need to work for many
hours without an AC power source, you may want to carry
additional charged battery packs with you. You can then replace a
discharged battery and continue working.

Battery safety precautions

Never try to disassemble a battery pack.
Never overcharge or reverse charge a battery. Overcharging
will shorten its life and reverse charging could destroy it,
causing the release of toxic fumes.
Avoid touching the metal terminals of the battery with another
metal object. Short circuiting the battery will cause it to
overheat and may cause permanent damage to the battery or
the computer.
Never incinerate a spent battery as this will cause it to
explode, releasing toxic materials.
If a battery is leaking or damaged, replace it immediately. Use
protective gloves when handling a damaged battery.
When you need to replace the battery, use an identical battery.

Charging batteries

The battery needs to be charged before you can use it to power the
computer. You can charge the battery using your computer or you
can use an optional battery charger.

Charging the battery

To charge the battery while it is in your computer, use the AC
adapter to connect the computer to a live wall outlet. With the
computer off, recharging the battery takes about three hours. The
battery takes much longer to charge when the computer is on. The
