ABSTRACT:
An improved explosion proof battery wherein the improvement comprises the separation of the gas flows in and out of each chamber from each other and the provision of check valves to each independent gas path to prevent the propagation of gas ignition from one cell to its neighbors when that ignition arises from within the battery. The battery and all of its elements are fabricated as a single substantially unitary structure.
