- Lithium ion Battery
Recharging the Batteries
If you want to know the condition of the primary Lithium ion battery, check the Battery Level indicator located on the
Status Indicator panel. The indicator changes as the battery level changes.
The Lithium ion battery is recharged internally using the AC adapter or Auto/Airline adapter. To recharge the battery
make sure the battery that needs to be charged is installed in your LIFEBOOK notebook and connect the AC or
Auto/Airline adapter.
There is no memory effect on the Lithium ion battery therefore you do not need to discharge the battery completely
before recharging. The charge times will be significantly longer if your notebook is in use while the battery is
charging. If you want to charge the battery more quickly, put your notebook into Standby mode, or turn it off while
the adapter is charging the battery See “Power Management” on page 40.
• ACTUAL BATTERY LIFE WILL VARY BASED ON SCREEN BRIGHTNESS, APPLICATIONS, FEATURES, POWER MANAGEMENT SETTINGS, BATTERY CONDITION
AND OTHER CUSTOMER PREFERENCES. CD-ROM DRIVE, MULTI-FORMAT DVD WRITER, OR HARD DRIVE USAGE MAY ALSO HAVE A SIGNIFICANT
IMPACT ON BATTERY LIFE. THE BATTERY CHARGING CAPACITY IS REDUCED AS THE BATTERY AGES. IF YOUR BATTERY IS RUNNING LOW QUICKLY, YOU
SHOULD REPLACE IT WITH A NEW ONE.
