Batteries: Dell Latitude LS Portable Computers User's Guide

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.

The battery status indicator (see Figure 1) turns orange while the battery is charging and then turns green when the charge cycle is complete. It takes about 1.5 hours to completely charge the battery, whether the computer is turned on or off.

NOTE: You can leave the battery in the computer as long as you like. The battery's integrated circuitry prevents the battery from overcharging.

Charging a Hot Battery

If your battery is hot from being used in your computer or being in a hot environment, take note of the following precautions:

A hot battery will not charge when you connect the AC adapter to the computer. This safety feature is important because charging a hot battery shortens the battery’s life span
