Abstract: A battery package for an integrated circuit having a container member with a floor and side walls; a pair of grooves through the inside surface of the side walls. A battery is disposed within the container, connected to two generally planar, electrically conductive contacts each having generally perpendicular, integral, pin portion formed on one end thereof. Each contact is attached to one of the battery terminals such that its pin is positioned within one of the grooves and extends above said upper container surface. The second contact is attached such that the portion of said second contact next adjacent said pin is positioned on a platform within the groove. A sealing composition envelops the battery, contacts, and a portion of the pins. The package is electrically attached to a dual-in-line integrated circuit member and the junction is sealed.
