ABSTRACT:
A reserve, energy sourced, or deferred action battery in which each battery cell is provided a separate reservoir containing the necessary electrolyte fluid for that cell. A simple design is then possible as the electrolyte fluid is stored in close proximity to the battery cells when needed at the time of activating the battery. A combination of two electrolyte fluids may be used that react exothermically when mixed together at the time of activation thereby producing heat. The production of heat allows the battery to activate at existing cold ambient temperatures that would otherwise render the reserve battery without sufficient operating power. The invention also provides an activation system which ensures reliable activation of the battery and ensures that the battery is not is subject to unintended activation.
