A low cost, relatively inexpensive and highly reliable tuned resonant circuit and method for prolonging the life of storage batteries of the type that contain a liquid electrolyte and are exposed to extensive periods of non-use. The resonant circuit is powered from a commercially available AC voltage source that is connected through a capacitor and a step down transformer to the input of a full wave diode rectification bridge. The output of the bridge rectifier is connected across the power terminals of the storage battery so as to supply a steady pulsating DC voltage thereto. By virtue of the foregoing, the battery electrolyte is excited so that the specific gravity thereof will be maintained at the original operating level of the electrolyte in a fully charged storage battery.
