Abstract
A battery powered portable electric light source has multiple sets of spare batteries contained in its battery compartment, whereby mixups between exhausted and fresh batteries are effectively avoided. A flashlight having a light output stronger than the mentioned electric light source is provided for use of batteries from the battery compartment of the mentioned portable container, and batteries are exchanged between that portable container and that flashlight. Apparatus for providing electric light have an electric light source requiring for energization a pair of batteries in series and a portable container for several pairs of these batteries connected each in series at a bottom of that container. Each of these several pairs of batteries includes a first battery having a first positive terminal and an opposite first negative terminal, and a second battery having a second positive terminal connected to that first negative terminal and an opposite second negative terminal. First positive terminals of first batteries of the several pairs of batteries and second negative terminals of second batteries of the several pairs of batteries are in substantially the same plane for selective application of the electric light source thereto for energization therefrom. A socket for the electric light source includes terminals corresponding to adjacent terminals of any one of the several pairs of batteries in that container. Unspent batteries in film packs may be used to energize light sources.
