- 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
60 for more information on Standby mode and shutdown procedure)
• 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, DVD/CD-RW DRIVE COMBO, 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.
• UNDER FEDERAL, STATE, OR LOCAL LAW IT MAY BE ILLEGAL TO DISPOSE OF BATTERIES BY PUTTING THEM IN
THE TRASH. PLEASE TAKE CARE OF OUR ENVIRONMENT AND DISPOSE OF BATTERIES PROPERLY. CHECK WITH
