Battery Rechargeablebattery Servicelife,battery Battery Battery
During use as a portable, the notebook runs on its built-in battery. You can increase
the service life of the battery by caring for the battery properly. The average battery
service life is around 500 charge/discharge cycles.
You can extend the battery service 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 if the ambient temperature is between
5°C / 41°F and a maximum of 35°C / 95°F.
You can charge the battery by connecting the notebook to the AC adapter
(see "Connecting the AC adapter", Page
If the battery is running low you will hear a warning alarm. If you do not connect the AC adapter
within five minutes of the warning alarm described above, your notebook will automatically switch off.
Monitoring the battery state of charge

Windows also has a "Battery charge meter" in the taskbar for monitoring the
battery capacity. When you place the mouse pointer on the battery symbol, the
system displays the state of charge of the battery.
Battery storage
Self-discharge,battery Chargecapacity,battery Battery Battery
The battery should be stored in a dry environment at a temperature between 0°C / 32°F and
30°C / 86°F. The lower the storage temperature, the lower the rate of self-discharge.
If you will be storing batteries for a longer period (more 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 optimum capacity of the battery, you should allow
the battery to fully discharge and then recharge it.
If you will not use batteries for long periods, remove them from the
notebook. Never store 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.
