During mobile use, the notebook runs on its built-in battery. You can increase the life of the battery
by caring for the battery properly. The average battery life is around 800 charge/discharge cycles.
You can extend the battery life by taking advantage of the available energy saving functions.

Charging, caring for and maintaining the battery

Battery Battery
The notebook battery can only be charged when the ambient temperature is
between 5°C / 41°F and max. 35°C / 95°F.
You can charge the battery by connecting the notebook to the mains adapter
(see "Mains adapter connecting", Page
If the mains adapter is connected when the state of charge of the battery is more than 90%,
charging will not be started. When the state of charge of the battery is less than 90%, the
battery will be charged to 100% as soon as the mains adapter is connected.
If 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.

Windows also has a "Battery status meter" in the taskbar for monitoring the battery capacity. When
you place the mouse pointer on the battery symbol, the system displays the battery status.
Battery storage
Self-discharge,battery Chargingcapacity,battery Battery Battery
Keep the battery pack in a dry environment at between 0°C / 32°F and 30°C / 86°F. The lower
the temperature at which the batteries are stored, the lower the rate of self-discharge.
If you will be storing batteries for a longer period (longer than two months),
the battery charge level should be approx. 30 %. To prevent exhaustive
discharge which would permanently damage the battery, check the level
of charge 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 device.

Removing and installing the battery

Only use batteries approved by Fujitsu for your notebook.
Never use force when fitting or removing a battery.
Make sure that no foreign bodies get into the battery connections.
Never store a battery for long periods in the discharged state. This
can make it impossible to recharge.
