US Patent:

44156383, Nov 15, 1983

Filed:

Sep 13, 1982

Appl. No.:

6/417041

Inventors:

Richard M. Meighan - Lansdale PA
Harry R. Cash - Jeffersonville PA

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

H01M 1006

US Classification:

429225

Abstract:

Improvements in a dry charged lead-acid storage battery and in a method for producing such a battery are disclosed. The improvements in the battery involve negative plates having an initial polarization, when on charge, not greater than zero; preferably, the positive plates have an initial polarization, when on charge, of at least 100 millivolts, and most desirably, from 150 to 180 millivolts. The improvements in the method involve, for example, reducing the initial polarization of the negative plates by partial discharge thereof after formation or by air or chemical oxidation. The battery of the invention is protected from catastrophic positive grid corrosion upon activation and consequent premature failure in service without the necessity for conventional (high voltage) boost-charging at the time of installation into a conventional float charging system.

Inventors:

Richard M. Meighan - Lansdale PA

Assignee:

Eltra Corporation - Toledo OH

International Classification:

H01M 1044

US Classification:

204 21

Abstract:

A process for the fabrication of lead acid batteries containing an acid electrolyte and negative electrodes and positive electrodes, including the steps of coating at least one said electrode with a paste containing tetrabasic lead sulfate and ammonium carbonate mixed with water, curing said electrode in a dry atmosphere, and forming said electrode.
