Disposal
Lithium ion batteries can be recycled. Their components can be used as raw materials for new
batteries or other products. A requirement for effective recycling is the collection of used
batteries.
Risk of fire - Hazardous to people and the environment
The improper disposal of batteries may cause fire.
Observe the local regulations for the disposal of recyclable materials.
Dispose of batteries properly.
Battery operation
The battery (lithium ion) enables mobile use of the device, independently of an external
power supply. It also protects against data loss in the even of a power failure.
The battery will start charging as soon as the device is connected to the power supply. In
doing so, the following conditions are important:
• When the device is switched off the charging process takes around 2 hours and 30
minutes.
• When the device is switched on, the duration of the charging process depends strongly
dependent on the system load and can be extended accordingly.
• The charging process is terminated as soon as the battery is fully charged.
• A charged battery will discharge itself during storage (depending on the temperature, and
whether or not it is installed) over a few months. It will then have to be recharged.
• The battery charging is terminated when the battery is fully charged or if, for example, the
upper temperature limit for charging is exceeded. You can check the battery charge level
in Windows.
• At high ambient temperatures the battery is protected against overheating by reducing
the charging current. The charging process can hereby extend accordingly.
• The battery protects itself at higher ambient temperatures by decreasing the charging
capacity. If the device is operated at lower ambient temperatures again, the charging
capacity of the battery increases again.
If, with a connected power supply unit, the battery LED lights up green, the battery is full and
will not be charged any further.
