Intelligent battery module for multimedia device

An intelligent battery device for electrically controlling at least one battery unit to provide electricity to a multimedia device which has a battery terminal and is operated by a designated multimedia battery, wherein said battery device comprises:

• a device housing, having a battery slot formed thereon, adapted for detachably mounting onto said multimedia device, wherein said multimedia battery is adapted for mounting onto said battery slot;
• and
• an intelligent circuit arrangement provided within said device housing for electrically communicating said multimedia battery and said battery unit with said battery terminal of said multimedia device, in such a manner that when said multimedia battery is mounted onto said battery slot, said intelligent circuit arrangement is adapted to electrically connect said multimedia battery with said battery terminal so as to allow said multimedia battery to initially activate said multimedia device, and when said multimedia device is initially activated by said multimedia battery, said intelligent circuit arrangement is arranged to electrically connect said battery unit with said battery terminal so as to allow said multimedia device to be continuously operated by said battery unit without electrically further recourse to electricity supply of said multimedia battery.

A method of providing an extended electricity supply to a multimedia device which has a battery terminal and is normally operated by a designated multimedia battery, comprising the steps of:

• (a) electrically connecting said multimedia battery with said multimedia device for initially activating said multimedia device by said multimedia battery through a predetermined communication protocol between said multimedia device and said multimedia battery;
• and
• (b) once said multimedia device is initially activated by said multimedia battery, electrically connecting a battery unit with said multimedia device such that said multimedia device is continuously operated by said battery unit without electrically further recourse to electricity supply of said multimedia battery, while retaining said communication protocol between said multimedia device and said multimedia battery.
