GU-21 POWERSAFE®

EnerSys GU-21 POWERSAFE® GU BATTERIES

PowerSafe® GU-21 batteries offer field-tested performance that meets industry requirements for long life and less maintenance. PowerSafe® GU batteries feature copper inserts in the posts maintain excellent short duration high-current performance, while individual posts enable individual cell monitoring, The PowerSafe® GU-21 also feature the Slide-Lock™ post seal that allows for natural plate growth over time without damaging the seal. PowerSafe® GU batteries are engineered for power industry demands and feature calcium plates for maximized performance in long distance applications. Extra thick positive grids and high temperature resistance make the PowerSafe® GU series one of the most rugged on the market.

Power Storage Solutions Installation and Service for GU-21

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
