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
