A battery especially useful in single use cameras has the insulative layer or wrapping removed therefrom to expose the metal jacket of the battery which functions as the positive terminal of the battery. The battery is then slid longitudinally into a cylindrical cavity in the camera to axially engage a first contact with the negative terminal of the battery and to be engaged radially by a second contact which contacts the metal jacket. In accordance with one embodiment of the invention, the metal jacket is contacted at a point between a groove in the jacket and a second end face of the battery which is unitary with the metal jacket. In accordance with a preferred embodiment of the invention, the second contact has a spring arm with an edge which engages a wall of the groove so as to prevent removal of the battery by the customer. A special battery extracting tool is provided at film developing centers for dislodging the second contact from the groove and pulling the battery from the cylindrical recess in the camera.
