Battery information
The headset is equipped with an integrated lithium-polymer battery. The
battery cannot be replaced. 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 HS 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
headset for a longer period of time. To avoid a complete discharge of the
battery, the BT HS 112 should be charged at least every 2 months.
