Lithium ion Battery
Your LifeBook notebook has a Lithium ion battery that provides power for operating your notebook when
no external power source is available. The battery is durable and long lasting, but should not be exposed
to extreme temperatures, high voltages, chemicals or other hazards.
The Lithium ion battery operating time may become shorter if it is used under the following conditions:
• When used at temperatures that exceed a low of 5°C or a high of 35°C. Extreme temperatures not
only reduce charging efficiency, but can also cause battery deterioration. The Charging icon on the
Status Indicator panel will flash when you try to charge a battery that is outside its operating
See “Status Indicator Panel” on page 20.
• When using a high current device such as a modem, Multi-Format DVD Writer, CD-ROM drive,
optical drive, or the hard drive, using the AC adapter will conserve your battery life.
