Polymer Battery
Your LifeBook notebook has a polymer 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 polymer 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.
•
When using a high current device such as an external optical drive, using the AC adapter will
conserve your battery life.
