Battery Performance
Use a battery to start the computer when it is not connected to an electrical outlet. One battery is supplied as standard equipment in the battery bay.
Battery operating time varies depending on operating conditions. With average use, you can expect from 3 to 4 hours for a single fully charged battery. You
can install an optional second battery in the module bay to significantly increase operating time. For more information about the second battery, see " Using
the Module Bay ."
Operating time is significantly reduced when you perform operations including, but not limited to, the following:
l Using optical drives, especially DVD and CD-RW drives
l Using wireless communications devices, PC Cards, or USB devices
l Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as 3D games
l Running the computer in maximum performance mode
You can check the battery charge before you insert the battery into the computer. You can also set power management options to alert you when the battery
charge is low .
Checking the Battery Charge
The Dell QuickSet battery meter, Microsoft® Windows® power meter window and icon, the battery charge gauge and health gauge, and the low-battery
warning provide information on the battery charge.
For more information about checking the charge on the second battery, see " Using the Module Bay ."

NOTE: You can conserve battery life by setting the Maximum Power Savings option for your graphics card. For more information, see the
documentation that came with your graphics card.
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 lithium-ion 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 your System 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.
NOTE: You can use your docking device to charge a computer battery. However, a battery in a docking device does not power the docking device or
computer.
