The notebook battery can only be charged, when the ambient temperature

You can charge the battery by connecting the notebook to the mains adapter

You can increase the life of your battery by allowing it to fully discharge before recharging it again.
To do this, leave your notebook turned on when it is operated with the battery. O nce the battery

minutes of the warning alarm described above, your notebook will automatically switch off.

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 batteries for a longer period (longer than two mon ths),
the battery charge level should be approx. 30 %. To prevent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at regular intervals.
To be able to ma ke use of the optimal charging capacity of the batteries, the battery
should be completely discharged and the n fully recharged.
If you do no t use the batteries for long periods, remove them from the
notebook. Never store the batteries in the device.
