EnerSys PowerSafe ESG Batteries

EnerSys PowerSafe ESG batteries are engineered with proprietary material and design features that deliver robust performance and reliable service to meet the demanding needs of the power industry. This makes the ESG battery ideal for challenging load profiles and service conditions. The five 4 volt (187 - 418 Ah) multi-cell unit construction helps to minimize floor space.

Standard features like thick positive plates ensure excellent long discharge capability while the copper insert post design enhances high rate performance. Individual posts easily accommodate monitoring and test equipment used in routine maintenance and inspections.

EnerSys PowerSafe ESG series batteries employ a Slide-Lock™ post seal that allows for natural plate growth over time for maximum reliability and reduced maintenance. The innovative tongue-and groove jar-to-cover seal provides a robust airtight seal.
All models are offered with 100% capacity out of the box for reliable operating performance from day one.
