Maximizing the battery's life
Like all other batteries, your computer's battery will degrade over
time. This means that the battery's performance will diminish with
time and use.
To maximize your battery's life, you are advised to adhere to the
recommendations set out below.
Conditioning a new battery pack
Before you use a battery pack for the first time, there is a
"conditioning" process that you should follow:
1. Insert the new battery without turning the computer on.
2. Connect the AC adapter and fully charge the battery.
3. Disconnect the AC adapter.
4. Turn on the computer and operate using battery power.
5. Fully deplete the battery.
6. Reconnect the AC adapter and fully charge the battery again.
Follow these steps again until the battery has been charged and
discharged three times.
Use this conditioning process for all new batteries, or if a battery
hasn't been used for a long time. If the computer is to be stored for
more than two weeks, you are advised to remove the battery pack
from the unit.
