1. A method for in situ forming a lead-acid battery having an electrolyte-absorbent plate separator to produce lead and lead dioxide surfacing of lead metal plates on respective sides of said separator, for electrochemical reaction between said plates and resultant electrical energy production by said battery, comprising the steps of:

  • a. cooling a supply of lead-acid battery electrolyte to below room temperature;

    b. introducing into the battery a quantity of said cooled lead-acid battery electrolyte less than the one hundred percent electrolyte-saturated capacity of said plates and said separators;

    c. charging said battery to oxidize and to reduce lead at the surfaces of respective plates to a preselected intermediate degree;

    d. filling said battery with water and/or acid sufficiently to provide at least the one hundred percent electrolyte-saturated capacity of said plates and separators; and

    e. further charging said battery to respectively further oxidize and reduce lead at said respective plates to a preselected degree defining a fully charged state of said battery.
