Charging, caring for and maintaining the battery
BatteryBattery
The notebook’s rechargeable battery can only be charged when the amb ient temperature
is between 5 °C / 41 °F and max. 35 °C / 95 °F.
If the battery is regularly charged at ambient temperatures above 25 °C,
this may reduce the battery life.
You ca n charg e the battery by conne cting the notebook to the m ains adap ter
(see "
Mains adapter connecting", Page 17).
Please note that the battery will not be charged if the battery status is between
90% and 100%. If the battery status is less than 90% and the mains adapter is
connected, the battery will be charged to 10 0%.
When the battery state of cha rge is low, a message from the op erating system appears.
If you do not connect the mains adapter within about 5 minutes of the message
appearing, you r notebook will automatically switch off.

Store battery packs in a dry environment at a temperature between 0 °C / 32 °F and 30 °C / 86 °F.
The lower the temperature at wh ich t he batteries are stored, the lower the rate of self-discharge.
If you will be s toring batteries for a longer period (more than two months),
the battery charge level should be approx. 30 %. To p revent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at regular intervals.
