Abstract: An interface for a mobile device battery is disclosed. The interface includes a U-shaped element, including an interior side and an exterior side, wherein a mobile device battery can be coupled to the interior side of the U-shaped element. The interface further includes at least one terminal coupled to the interior side of the U-shaped element, wherein each terminal contacts a battery contact of the mobile device battery when the mobile device battery is coupled to the interior side of the U-shaped element. The interface further includes at least one conductive element, wherein each conductive element is coupled to a terminal and provides a conductive contact on the exterior side of the U-shaped element for contacting a printed circuit board terminal.

Abstract: A combination handheld mobile telephone and wireless mouse for navigating a Windows®-based operating system of a computer comprises a telephone battery that is transformed to accommodate the electronics of the mouse. The mouse is attached to the telephone by connecting means that replaces the original (old) telephone backing or housing with the mouse. The telephone battery is modified to provide electrical contacts, preferably on the side opposed the side that employs electrical contacts to power the telephone, to power the mouse. In this regard, the combined mobile telephone and wireless/optical mouse can run simultaneously, both drawing and sharing power from the same telephone battery.
