4DSG-11 POWERSAFE®

EnerSys 4DSG-11 POWERSAFE® DSG BATTERIES

POWERSAFE® 4DSG-11 BATTERIES HAVE BEEN CAREFULLY ENGINEERED TO TAKE ON THE DEMANDING POWER NEEDS OF THE UTILITY MARKET. THE MULTI-CELL DESIGN WITH INDIVIDUAL POST UTILIZES LESS FLOOR SPACE WHILE ALLOWING FOR INTEGRATION OF BATTERY MONITORING AND TEST EQUIPMENT USED IN ROUTINE MAINTENANCE.

PowerSafe DSG 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. Multi-cell construction requires fewer units, resulting in lower installation costs.

The 0.25" thick positive plate makes DSG batteries ideally suited for the long duration and complex duty cycle requirements inherent to todays switchgear, utility and control applications. All battery systems are rated at 100% capacity at initial discharge and offer 20-year life expectancy in float service at 77°F (25°C) ambient temperature.

Power Storage Solutions Installation and Service for 4DSG-11

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
