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-

cycles. The battery can be charged and discharged several hundred times,

but it looses its capacity over time.

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.
