When not plugged into a mains socket, the notebook runs on its built-in battery. You
can increase the life of the battery by caring for the battery properly. The average
battery life is around 500 charge/discharge cycles.
You can extend the battery life by taking advantage of the available energy saving functions.

Windows also has a "Battery status meter" in the taskbar for monitoring the battery capacity. When
you place the mouse pointer on the battery symbol, the system displays the battery status.
The battery capacity can be monitored using an indicator which shows the current state
of charge. Use the following menu to enable this feature:

The indicator is then displayed in the task bar as a battery symbol. When you place the
mouse pointer on the battery symbol, the system displays the battery state of charge. Please
refer to the Help facility of the operating system for more information.

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 months),
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 make use of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharged.
If you do not use the batteries for long periods, remove them from the
notebook. Never store the batteries in the device.
