Abstract

A lead acid battery life extender for the battery of an internal combustion engine includes a multivibrator circuit electrically connected across the terminals of the battery for delivering high frequency electrical pulses to the battery, thereby removing lead sulfate from the plates of the battery and increasing the life of the battery, and a thermoelectric power source for providing electrical energy to the multivibrator circuit, thermally coupled to heat emitted from the internal combustion engine and electrically connected to the multivibrator circuit.
