Battery System with Integral Racking System

EnerSys Reserve Power Group has a battery system that combines an enhanced cell design with an integral racking system. The PowerSafe DDm provides long service life and desirable performance for a variety of applications that require large capacity valve-regulated batteries including telecommunications, power generation, and distribution and uninterruptible power supply (UPS) applications.

The cell design incorporates 0.25 positive plates for a battery life of up to 20 years. The battery cells have welded epoxy, dual post seals that are 100% water bath tested in the factory. Lead-casted terminal posts include a large threaded copper insert that enhances the high-rate performance with maximum conductivity.

DDm battery cells are encased in dedicated protective steel cans, or modules, that provide uniform and consistent compression for the life of the cell as well as protection during transport and installation. The design incorporates thermal management allowing maximum airflow, and the one-piece container improves leak resistence.

The EnerSys batteries do not have to be removed from the modules during installation. Users set up the rack and install the modules in configurations of two, three, four, or six cells wide, and up to eight cells high. The system provides complete front access of the batteries for ease of maintenance. Top termination is standard for shorter connection to the overhead bus, with optional side termination available. The company offers a wide range of models from 200Ah to 2,000Ah in a single cell.
