Using the Battery
The battery is partially charged when you receive it. Dell recommends that you charge your battery to full capacity before using it to power the
computer.
If you are powering the computer from a battery, try to conserve battery power. A number of factors affect battery operating time:
Power conservation features that you use
l
Type of display and microprocessor installed
l
Brightness setting of the display
l
Use of storage media
l
Number and type of external devices and type of PC Cards that you use

If you are going to store the computer, disconnect all devices and turn off the computer. Remove the battery when you store your computer for an
extended period of time. A battery will drain when not in use during prolonged storage. After a long storage period, recharge the battery fully before
you attempt to run your computer from battery power.
NOTE: To extend battery life, store batteries at room temperature.
Charging the Battery
Each time you connect the computer to an electrical outlet or install a battery in a computer that is connected to an electrical outlet, the computer
checks the battery's charge. The AC adapter charges the battery (if needed) and then maintains the battery's charge.
NOTE: For maximum battery performance, charge the battery only at room temperature.
