The Power High-Rate Series of valve regulated lead acid (V.R.L.A.) batteries have been developed and refined since 1972. It is the battery of choice for many OEM's and users throughout the world. Our state of the art V.R.L.A. design utilizes an absorbed glass mat (A.G.M.) separator technology to immobilize the battery electrolyte. There is never any need to add water to the cells and in fact all vents are factory sealed. These batteries are the ideal choice for U.P.S., emergency lighting, switchgear and other standby applications which need reliable, high rate power. Since these batteries are low-gassing they require no special ventilation. Please browse our batteries and feel free to contact APTC with any questions or quote requests!
