The PowerSafe® DDm battery range offers an ideal solution for large capacity Valve Regulated Lead Acid (VRLA) battery requirements. The PowerSafe DDm battery’s steel can (module) design, with its integral racking system, provides a cost effective battery system. This creates a compact, quick and simple installation process. The PowerSafe DDm battery system’s cutting-edge technology incorporates an enhanced cell design with a superior racking system. The enhanced cell incorporates thicker positive plates for longer life. The welded/epoxy, dual post seal design provides the highest integrity seal in the industry. The large copper post design also enhances the high rate performance. Cells are encased in dedicated protective steel cans (modules) that maintain constant, uniform compression for the life of the cell. The easy to assemble racking system provides total flexibility for system configuration and its built-in thermal management allows air flow between the cells, resulting in fast, effortless installation even in the most difficult locations. The PowerSafe DDm battery, with its optimized recombination technology and extra thick plates, provides excellent performance and service life for mission critical systems.
