5.2.10 Maximizing Battery Life
A battery can be recharged many times, but over time it will
lose its ability to hold a charge. To maximize battery life:
Don't leave your notebook plugged in and unused for
more than a few hours. Overcharging may shorten
battery life.
If you will not be using your notebook for a long period,
remove the battery.
If you have a spare battery pack, alternate the
batteries.
Ensure your notebook is off when replacing the
battery.
Store spare battery packs in a cool, dry place, out of
direct sunlight.
