You can install an optional second battery in the media bay to significantly increase operating time. For additional information about using a second battery, see "Media Bay" in the online User's Guide for your computer. NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer. Battery operating time varies depending on operating conditions. Operating time is significantly reduced when you perform operations including, but not limited to, the following: • Using optical drives • Using wireless communications devices, PC Cards, ExpressCards, media memory cards, or USB devices • Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as complex 3D graphics applications • Running the computer in maximum performance mode (See "Configuring Power Management Settings" in the online User's Guide for your computer.) NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or DVD. You can check the battery charge (see "Checking the Battery Charge" on page 14) before you insert the battery into the computer. You can also set power management options to alert you when the battery charge is low (see "Configuring Power Management Settings" in the online User's Guide for your computer).

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.
