The notebook battery can only be charged, when the ambient temperature
is between 5°C and max. 35°C.

Battery storage
BatteryBatterySelf-discharge,batteryChargingc apac ity,battery
Keep th e battery pack between 0°C an d +30°C. The lower the temperature at which
the batteries are stored, the lower the rate of s elf-discharge.
If you will be storing batteries for a longer period (longer than two months),
the battery charge level should be approx. 30 %. To prevent exhaustive
discharge which would permanen tly dam age the battery, check the level
of charge of the battery at regular intervals.
To be able t o make use of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharg ed.
If you do not use the batteries for long periods, remove them from the
notebook. Never store the batteries in the device.
