Abstract: A battery system having lead-acid cells, vertically upstanding cell support frame for supporting the cells, vertically upstanding members with receptacle means for slidably receiving and retaining vertical cell supports, and manually assemble means for connectively maintaining and spacing the upstanding members for receipt of the cell supports. The cells have horizontal positive and negative sandwiched lead-metal plates contained within a cell case resting on the vertical supports. The case has an expandable region surrounding the terminal for relieving pressure on that terminal from grid expansion while simultaneously maintaining the integrity of the case seal to the terminal. The cell support frame includes an elongated strap external of the case for connecting together terminals of the cell and having an output terminal and a central portion on the strap for electric communication with another battery.

Abstract: The subject invention provides a tray assembly for use in forming a sealed lead-acid battery system which houses multiple battery cells in horizontal positions for motive-power applications. In one aspect of the subject invention, the battery system includes a plurality of sealed lead-acid battery cells, and a housing having a plurality of walls which define an interior for accommodating the battery cells. At least one tray insert bears against a base of the housing which partitions the interior into at least two compartments for accommodating the battery cells. In a second aspect of the subject invention, a sealed lead-acid battery system for motive-power applications may be provided which utilizes at least one spacer partially disposed between two battery cells to cause separation thereof.

Abstract: A sealed-lead acid battery system for standby applications is arranged in a vertically stacked array utilizing molded plastic modules to construct a battery. The modules may support a plurality of battery cells either mounted horizontally (with the plates parallel to module bottom) or vertically (with the plates perpendicular to module bottom). The modules include an interconnecting structure to permit interconnecting vertical stacking of the modules. The structural plastic modules are capable of being stacked several tiers high and withstanding seismic accelerations in accordance with industry seismic codes.
