Battery information
The device is equipped with an integrated lithium-polymer battery. The battery cannot be replaced.
Do not attempt to remove the battery from the device since it would damage the device. The full
performance of a new battery is not achieved until after two or three complete charging-discharging
cycles. The battery can be charged and discharged several hundred times, but it looses its capacity
over time.
Disconnect the BT Drive Free 112 from the power supply as soon as the battery is fully charged,
since overcharging would reduce the service life of the battery. A charged battery looses its capacity
if it is not used. Important: Ensure that the battery is fully charged if you do not use the device for a
longer period of time. To avoid a complete discharge of the battery, the BT Drive Free 112 should be
charged at least every 2 months.

You have to remove the BT Drive Free 112 from the Sun visor for the charging procedure. Connect
the BT Drive Free 112 with the vehicle charging adapter via the USB cable. Insert the vehicle
charging adapter into the cigarette lighter of the vehicle. The BT Drive Free 112 can also be charged
with the USB cable connected to the computer.
