When not plugged into a m a ins socket, 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 500 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

The notebook battery can only be charg ed, when the ambient temperature
is between 5°C and max. 35°C.
You can charge the battery by connecting the notebook to the mains adapter
(see "
Mains adapter c onnecting", Page 16).
You can increase the life of you r battery by allowing it to fully discharge before r echarging 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 a larm. If you do not connect the mains a dapter within five
minutes of the warning alarm described above, your notebook will automatically switch off.

Battery storage
BatteryBatterySelf-discharge,batteryChargingc apac ity,battery
Keep th e battery pack between 0°C and +30°C. T he lower the temperature at w hich
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 batte ry charge level should be approx. 30 %. To prevent exhaustive
discharge which would permanently dam age 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 no t use the batteries for long periods, remove them from the
notebook. Never store the ba tteries in the device.
