Abstract: A DEFERRED ACTION BATTERY IS DESCRIBED HAVING A CYLINDRICAL PLASTIC CONTAINER WITH METALLIC TERMINAL CONTACT PIECES AT EITHER END. THE BATTERY PLATES ARE ANNULAR IN SHAPE AND DEFINE A CENTRAL CYLINDRICAL CAVITY. WITHIN THE CAVITY ARE LOCATED A BISCUIT OF DRY PRESSED ELECTROLYTE, AN AMPOULE CONTAINING A SOLUTION OF POASSIUM CHROMATE, AND A PLUNGER. A PORTION OF THE PLUNGER PASSES THROUGH THE TOP OF THE BATTERY CONTAINER. THE BATTERY IS ACTIVATED BY FORCING THE PLUNGER INTO THE AMPOULE CAUSING IT TO BREAK. THE LIQUID WITHIN THEN DISSOLVES THE PERCHLORATE TO GIVE THE DESIRED ELECTROLYTE WHICH THEN PERMEATES AND ACTIVATES THE BATTERY.
