Claims: We claim as our invention:

1. A lead-acid storage battery comprising a container having a plurality of cell compartments and a plurality of battery elements consisting of a plurality of positive and negative charged plates with separators positioned therebetween disposed in the cell compartments, said battery being sealed to at least substantially prevent the ingress of air and said battery elements containing a conditioning amount of a metallic sulfate and residual electrolyte and said battery being otherwise substantially free of electrolyte and being activatable by addition of electrolyte thereto.

2. The lead-acid storage battery of claim 1 wherein said metallic sulfate is sodium sulfate.

3. A lead-acid storage battery comprising a container having a plurality of cell compartments and a plurality of battery elements consisting of a plurality of positive and negative charged plates with separators positioned therebetween disposed in the cell compartments, said battery being sealed to at least substantially prevent the ingress of air and said battery elements containing residual electrolyte and a conditioning amount of a soluble metallic sulfate sufficient to prevent crystal growths and clusters extending between adjacent positive and negative plates and said battery being otherwise substantially free of electrolyte and being activatable by addition of electrolyte thereto.

4. The lead-acid storage battery of claim 3 wherein said metallic sulfate is a sulfate selected from the group consisting of sodium, potassium, lithium, magnesium, cadmium, zinc, aluminum, silver, cobalt, beryllium, cerium, indium, lanthanum, tin, thallium, zirconium, rubidium and mixtures thereof.

5. The lead-acid storage battery of claim 4 wherein the metallic sulfate is sodium sulfate.

6. The lead-acid storage battery of claim 4 wherein the metallic sulfate is zinc sulfate.

7. The lead-acid storage battery of claim 4 wherein the metallic sulfate is potassium sulfate.

8. The lead-acid storage battery of claim 4 wherein the metallic sulfate is lithium sulfate.

9. The lead-acid storage battery of claim 4 wherein the metallic sulfate is magnesium sulfate.

10. The lead-acid storage battery of claim 4 wherein the metallic sulfate is cadmium sulfate.

11. The lead-acid storage battery of claim 4 wherein the metallic sulfate is aluminum sulfate.

12. A lead-acid storage battery comprising a container having a plurality of cell compartments and a plurality of formed battery elements consisting of a plurality of positive and negative charged plates with separators positioned therebetween disposed in the cell compartments, said battery being sealed to at least substantially prevent the ingress of air and having been drained of electrolyte, said battery elements containing a conditioning amount of a metallic sulfate and residual electrolyte and said battery being activatable by addition of electrolyte thereto.
