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

The notebook battery can only be charged if the ambient tempera ture 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

The b attery should be sto red in a dry e nvironment at a temperature between 0°C / 32°F and
30°C / 8 6°F. The lower the storage temperature, the l ower the rate of self-discharge.
If you will be s toring ba tteries for a longer period (more than two mo nths),
the battery charge level should be approx. 30%. To p revent exhaustive
discharge which would permanently damage the battery, c heck the level
of charge of the battery at regular intervals.
