ESG-21FR POWERSAFE®

EnerSys ESG-21FR POWERSAFE® ESG BATTERIES

PowerSafe® ESG-21FR batteries are engineered with proprietary material and design features that deliver robust performance and reliable service life. 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. All PowerSafe ESG batteries have individual posts for each cell to help ease and simplify the integration
of battery monitoring and test equipment used in routine maintenance and inspections.

PowerSafe ESG batteries have thick positive plates that ensure excellent long discharge capability. Copper insert posts enhance high-rate performance. Individual posts easily accommodate monitoring and test equipment used in routine maintenance and inspections. PowerSafe ESG batteries also employ a Slide-Lock™ post seal that allows for natural plate growth over time, plus a tongue-and groove jar-to-cover seal that provides a robust airtight seal for maximum reliability and reduced maintenance.

Power Storage Solutions Installation and Service for ESG-21FR

We understand that data centers are heavily reliant on batteries for backup power. We also understand that batteries must be redundant and if only one battery in your UPS configuration is not performing; it compromises your overall backup power. Our experience and our focus is to know the batteries and their implication for your operation. To determine the perfect solution, we will partner with you, analyze your critical power needs and construct the backup power solution that will perform as designed.

We can remove and recycle your old battery system then install, properly set up and test your new system. We have been installing stationary batteries for over 20 years. We have the experience, equipment and capabilities to safely perform this type of work.

Routine maintenance ensures your UPS equipment stays reliable, improving your UPS’s overall performance and extending their useful life. Service plans allow customers to be proactive; providing opportunity to detect potential points of failure preventing expensive problems.

When ordering new batteries, also remember to properly recycle your old lead batteries. Federal and state regulations require lead-acid batteries be recycled. Power Storage Solutions’ nationwide service organization can arrange pickup, transportation to and recycling at any one of our company affiliated smelters. Click Here for More Information
