Operating on battery power

A fully charged battery provides approximately three hours of use if the system is set to maximum volume. However, the rate of battery discharge varies with the type of music played and the volume setting. You can extend the battery operating time significantly by lowering the volume.

The battery status light on the Bose® system indicates when charging the battery is necessary. For information on charging the battery, see Charging the battery.
