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 20.
• When using a high current device such as a Multi-Format DVD Writer, optical drive, or the hard drive, using the
AC adapter will conserve your battery life.
