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
temperature range. See "Status Indicator Panel" on page 22.
• When using a high current device such as a modem, Multi-Format DVD Writer, external CD-ROM
drive, DVD/CD-RW combo drive, or the hard drive, using the AC adapter will conserve your
battery life.
