A battery container is of a size to accommodate two "AA" batteries situated side by side, or one "transistor" size battery. The container has two independent electrical contacts located at one end to make electrical contacts with the terminals of the "transistor" battery or with one of the ends of both "AA" size batteries. A retainer is located at another end of the container. The retainer provides electrical contact with the other ends of both "AA" size batteries. In addition, the retainer exerts pressure in the length direction to accommodate the smaller length of the "AA" or the "transistor" battery and exerts pressure in the width direction to accommodate the smaller width of the two "AA" or the "transistor" battery.
