32 Using a Battery
CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only
with a compatible battery purchased from Dell. The battery is designed to work with your Dell computer. Do not
use a battery from other computers with your computer.
CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a charge, call
your local waste disposal or environmental agency for advice on disposing of a lithium-ion battery. See "Battery
Disposal" in the
Product Information Guide
.
CAUTION: Misuse of the battery may increase the risk of fire or chemical burn. Do not puncture, incinerate,
disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery away from children.
Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury
or equipment damage.
Checking the Battery Charge
The Dell QuickSet Battery Meter, the Microsoft Windows Power Meter window and battery meter icon
( or ), the battery charge gauge and health gauge, and the low-battery warning provide
information on the battery charge.

Dell™ QuickSet Battery Meter

If Dell QuickSet is installed, press <Fn><F3> to display the QuickSet Battery Meter. The Battery
Meter displays status, battery health, charge level, and charge completion time for the battery in your
computer.
For more information about QuickSet, right-click the QuickSet icon in the taskbar, and click Help.

Microsoft® Windows® Power Meter

The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, double-
click the battery meter icon ( or ) on the taskbar.
If the computer is connected to an electrical outlet, a icon appears.

Charge Gauge

By either pressing once or pressing and holding the status button on the charge gauge on the battery, you
can check:
Battery charge (check by pressing and
releasing
the status button)
Battery health (check by pressing and
holding
the status button)
The battery operating time is largely determined by the number of times it is charged. After hundreds of
charge and discharge cycles, batteries lose some charge capacity—or battery health. That is, a battery can
show a status of "charged" but maintain a reduced charge capacity (health).
