ABSTRACT:
An intelligent battery module for a multimedia device includes a device housing, a battery unit and an intelligent circuit arrangement. The intelligent circuit arrangement is provided within the device housing for electrically communicating a multimedia battery and the battery unit with a battery terminal of the multimedia device, in such a manner that when the multimedia battery is mounted onto a battery slot, the intelligent circuit arrangement is adapted to electrically connect the multimedia battery with the battery terminal so as to allow the multimedia battery to initially activate the multimedia device, and when the multimedia device is initially activated by the multimedia battery, the intelligent circuit arrangement is arranged to electrically connect the battery unit with the battery terminal so as to allow the multimedia device to be continuously operated by the battery unit without electrically further recourse to electricity supply of the multimedia battery.
