When not plugged into a m ains socket, the no tebook runs o n 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 maintain ing the battery
BatteryBattery
The notebook battery can only be charged, wh en the ambient temperature
is between 5°C and max. 35°C.
You can charge the ba ttery by connecting the noteboo k to th e mains adapter

Windows also has a "Battery status meter" in the ta skbar for m o nitoring the battery capacity. When
you place the mouse pointer on the battery symbol, the system displays the battery status.
Battery storage
BatteryBatterySelf- discharge,batteryChargingcapac ity,battery
Keep the battery pack between 0°C and +30°C. The lower the temperature at which
the batteries are stored, the lower the rate of self-discharge.
If you will be storing ba tteries for a longer period (longer than two months),
the b attery charge level should be approx. 30 % . To prevent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the ba ttery at regular intervals.
To be able to make u se 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.
