EnerSys PowerSafe mSeries VRLA

EnerSys PowerSafe mseries

The EnerSys PowerSafe mSeries battery system offers an ideal solution for large capacity Valve Regulated Lead Acid (VRLA) battery requirements. The system’s steel can (module) design with its integral racking system, provides a cost effective battery system with a compact, quick and simple installation process. The PowerSafe mSeries battery system’s cutting-edge technology incorporates an enhanced cell design with thicker positive plates for longer life. The welded/epoxy, dual post seal design provides the highest seal integrity in the industry. Copper inserted square post design enhances the performance. The batteries are encased in dedicated protective steel cans (modules) that maintain constant, uniform compression for the life of the battery. The racking system provides total flexibility for system configuration and allows fast, simple installation, while providing necessary robustness for NEBS™ requirements.

EnerSys PowerSafe mSeries cells, with their optimized recombination technology and extra thick plates, provide excellent performance and service life across a wide range of telecommunications.
