ABSTRACT OF THE DISCLOSURE A method of manufacturing a lead-acid storage battery capable of being stored after completing the battery processing and thereafter activated by the addition of water including coordinating the formation and processing of the battery elements with a deep discharge to provide residual sulfuric acid electrolyte within the battery elements with a desired specific gravity level and thereafter reducing the amount of the electrolyte in the battery to thereby retain a specified level of residual sulfuric acid electrolyte within the elements of the thus-processed battery. The battery is suitably sealed and may thereafter be stored; and, when desired for service, activation is accomplished by addition of water and suitably charging. The sulfate in the battery elements resulting from the deep discharge and the residual sulfuric acid electrolyte retained within the elements combine, upon the addition of water and recharge, to yield the required specific gravity of the electrolyte. In a preferred embodiment, the battery is conditioned with a treating agent affording certain metallic sulfates to enhance the useful battery storage life and the ability of the battery to accept the required charge after water addition.
