Battery Handles Challenging Load Profiles


PowerSafe ESG battery is designed to provide 185 to 960Ah of capacity range to handle the challenging load profiles and service conditions of utility applications.


The configuration of five multi-cell 4-volt units (185, 234, 281, 354 and 418Ah) reduces the footprint of the battery to enable minimal occupation of floor space. Individual terminal posts on each cell facilitate integration of battery monitoring and test equipment used in routine maintenance and inspection. The Slide-Lock post seal accommodates natural plate growth over time for maximum reliability and reduced maintenance. Additionally, the tongue-and-groove jar-to-cover seal provides a robust airtight seal.


The capacity range of 185 to 960Ah is rated at eight hours to 1.75 v per cell (Vpc) at 77°F (25°C). Initial capacity is rated at 100%. Other features of the PowerSafe ESG battery include cast lead posts with copper inserts and a dual-hole design that can handle the most demanding one-minute rates, which are characteristic of utility load profiles. The ESG line offers a 20-year life expectancy in float service at 77°F (25°C) ambient temperature.
