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 bat-
tery 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 411 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 411 should be charged at least every 2 months.
