An Advanced Graphite deep discharge lead acid battery is described including: a deep storage lead acid cell energy storage device comprises: an electrode comprising lead; an electrode comprising lead dioxide; a separator between the electrode comprising lead and the electrode comprising lead dioxide; an aqueous solution electrolyte containing sulfuric acid; and a carbon-based additive having a specific surface area of approximately 250 to 550 m/g.

Advanced graphite additive for enhanced cycle-life of deep discharge lead-acid batteries

A lead acid cell including a positive plate or grid has been discovered involving Pb/Ca/Sn/Ag alloy. An interaction between tin and silver which leads to optimum tin and silver levels which are substantially different than those indicated in the prior art. The described optimum tin and silver levels results in a positive alloy with superior mechanical properties and improved corrosion resistance which leads to superior battery life in present day SLI applications. In a preferred manner, the alloy includes lead, tin in the range of about 0.8% to about 1.17%, and silver in the range of grater than 0 to about 0.015%, the percentages being based upon the total weight of the lead-based alloy.

Alloy for battery grids

A self-latching handle for storage batteries includes a cam mechanism formed integrally with the ends of the battery handle, the cam mechanism cooperating with the battery housing as the battery handle is rotated downwardly from a vertical attachment position to a horizontal storage position to lift the ends of the battery handle to move pivot post portions of the battery handle into pivot apertures formed in the cover of the battery housing and to lock the battery handle to the battery housing while permitting the battery handle to be pivoted between the horizontal storage position and a vertical use position without becoming detached from the battery housing.

Self-latching handle for storage batteries

A battery system is disclosed which includes folded grids of expanded metal inserted through non-conductive substrates and pasted with electrochemically active materials. In the most preferred embodiment, a frame is provided with a plastic insert, and slots are provided in the latter to receive the expanded metal grid. After suitable coinage of the grid and insertion through the plastic film, the grid is sealed and pasted on opposite sides with positive and negative active material. A battery is assembled using one or a plurality of the resulting electrode elements, with separators, to produce a high-power, lead-acid battery. The folded grid provides many of the design benefits of standard bipolar construction.
