SEC Sterling AGM Batteries Leaflet

SEC UK - Sterling series of AGM batteries

High integrity reliability for critical backup power applications, the maintenance free valve regulated lead acid (VRLA) construction make Sterling HP & HPX series batteries the definitive choice for UPS, telecom and utility applications.

Sterling HP & HPX series are constructed with proprietary grid alloy & active material with a unique plate curing manufacturing process. This process allows for 99% gas recombination, providing extended float service life. From grid design to curing & formation, every facet of the manufacturing process is controlled and completed in one production facility utilizing cutting edge, fully automated production technologies. Standards for quality control are among the highest in the industry & are ISO certified.
