EnerSys PowerSafe DDr 50-13 Batteries
with recombinant technology means no watering is required throughout the life of the product, yielding reduced overall maintenance costs. The battery features a welded/epoxy, dual post seal design which provides the highest integrity seal in the industry.

Each DDr battery is protected in a dedicated protective steel case that maintains constant, uniform compression for the life of the cell, preventing separation of the internal components and dry out of the Advanced Glass Mat (AGM) material.
