FR (VRLA) Series

The FORTUNER sealed lead-acid rechargeable battery is non-spillable and maintenance-free. A VRLA (valve-regulated lead acid) battery is a starved electrolyte AGM type battery and has a safety valve that prevents excessive build-up of gas pressure inside the battery. Valve-regulated lead acid batteries rely upon internal gas recombination to minimize electrolyte loss over the life of the battery, thereby eliminating the need for re-watering. A lead-acid battery has lead positive plates, lead oxide negative plates, and an electrolyte which is a solution of sulfuric acid and distilled water. The plates and the plate separator material between them are arranged in plate packs in plate compartments. VRLA batteries are particularly suited for remote backup power applications because they do not require the same type of periodic maintenance required by flooded cells. These differing maintenance requirements provide cost savings.
