PowerSafe® D Batteries

Engineered for telecommunications, utility and switchgear applications, PowerSafe® D batteries are available in the DU and DSG series. PowerSafe DU batteries are designed to handle the demanding float and deep discharges typical for telecommunication applications, while PowerSafe DSG batteries have lower watering requirements, making them ideal for challenging utility switchgear applications.

PowerSafe DU and DSG series

Featuring flat plate lead-calcium grid alloy design, PowerSafe DU batteries deliver the industry's largest amp-hour capacity of any four-cell battery. Multi-cell construction and full plate edge visibility shortens installation time, simplifies maintenance and reduces the battery string footprint. PowerSafe DSG batteries feature a lead-calcium design that reduces the watering intervals associated with lead-antimony batteries. The 0.25-inch thick positive grids enable long discharge, while individual posts for each cell allow easy monitoring and testing.

  • Capacity range: 295 to 745 Ah
  • 20-year life expectancy in float service at 77°F (25°C)
  • Slide-Lock™ post seal design protects seal while allowing for plate growth
