Fujitsu LIFEBOOK S Series - Battery; Charging, Caring for and Maintaining the Battery

Using your notebook
Battery
The battery supplies your notebook with the necessary power during mobile use. You can increase
battery life by enabling the system's power management features.
The battery charge is indicated by the battery symbol in the status indicator panel (see also section
"Indicators") When you switch on the notebook, it takes a few seconds before the battery status is
displayed.
The life of the battery is dependent on its proper storage, the number of charging/discharging cycles
and the operating temperature of the notebook.
Charging, caring for and maintaining the battery
Only use batteries approved by Fujitsu Siemens Computers for your notebook.
Take care not to drop the batteries or otherwise damage their casing (fire risk).
If the rechargeable batteries develop a fault please stop using them immediately.
Do not touch the contacts of the batteries.
Never interconnect the positive and negative terminals of a battery.
Batteries are harmful to the environment. You should dispose of them following guidance
from your local District Council.
!
Observe the information on battery storage in the "Important notes" chapter.
Information on the battery charging time is contained in the "Technical data" chapter.
You can charge the battery by connecting the notebook to the power adapter.
The battery can only be charged when the ambient temperature is between 5°C and max. 40°C.
You can maintain long life from your battery by allowing it to discharge fully before you recharge it
again. To do this, leave your notebook turned on when it is operated with the battery. Once the
battery is running low you will hear a warning alarm. If you do not connect the mains adapter within
five minutes of the warning alarm described above, your notebook will automatically switch off.
Storing the battery
Keep the battery pack between 0°C and +30°C (32 and 122 degrees Fahrenheit). The lower the
temperature at which the batteries are stored, the lower is the rate of self-discharge.
If you store rechargeable batteries for a longer period (longer than two months), the battery charge
level should be approx. 30%. To prevent exhaustive discharge, check the charging level of the
battery at regular intervals.
To be able to make use of the optimal charging capacity of the batteries, the battery should be
completely discharged and then fully recharged.
If you do not use the batteries for long periods, remove them from the notebook. Never
store the batteries in the unit.
