Best selling black mono bluetooth headset for mobile phone

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 as 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 loses its capacity over time.

Disconnect the CITYEYE from the power supply as soon as the battery is fully charged, overcharging would reduce the service life of the battery. A charged battery will lose its capacity if it is not used on a regular basis.

Important: Ensure that the battery is fully charged if you do not use the device for a long period of time. To avoid a complete discharge of the battery, the CITYEYE should be charged at least every 6months.

NOTE:

- For first time use, please charge the headset fully.

- The fully charged battery has power for up to 3 hours of talk-time, and up to 100hours of standby time. However, the talk and standby times may vary when used with different mobile phones or other compatible Bluetooth® devices, usage settings, usage styles, and environments. When the battery power is low, the headset will remind you by tonesevery 5seconds, and the red indicator light starts to flash.
