The notebook battery can only be charge d when the ambient temperature is
between 5°C / 41°F and max. 35°C / 95°F.
You c an charge the battery by con necting the notebook to the mains adapter
(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 stat us is less than 90% and the mains adapter is

Store battery packs in a dry environ m ent at a temperature between 0°C / 32°F and 30°C / 86°F. The
lower the temperature at which the batteries are stored, 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 exh aust ive
discharge which wo uld perma nently damage 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 batte ries, the battery
should be completely discharged and then fully recharged.
If you do not intend to use a battery for long periods of time, remove it from
the notebook. Never store a battery in the device.
