Abstract
A battery life extender for a lead-acid storage battery is provided and comprises a mixtures of polyvinyl alcohol, polylysine, and potassium or sodium sorbate (or sorbic acid), and optionally a preservative, such as sodium benzoate. The extender is added to a lead-acid storage battery. Distilled or deionized water can be included to adjust the specific gravity of the electrolyte. The extender substantially increases the operable life of lead-acid storage batteries.
