Features: Performance: IPF plate trough formation process ensures consistency between the cell voltage. Low self-sealing valve independent 100% tested to prevent the loss of early battery failure. All batteries are equipped with fire retardant membrane to enhance security. Epoxy sealed pole pole design eliminates leakage, extending battery life and protect the surrounding sophisticated electronic equipment, and by 100% factory tested to ensure long life and performance. Advanced absorbent glass fiber separator (AGM) technology uses a special ultrafine microporous membrane to adsorb all the electrolyte and reduce internal resistance and increase capacity, the effective use of space and eliminate the leak to ensure the safety of the installation and storage. Fight through the glass fiber membrane to provide a low resistance high rate discharge while avoiding failure and short battery to extend battery life. Durable heavy duty double coated plates thickened cream plates and 10-year design life. Special grid alloy are pure lead, low calcium and high-tin alloy provides fast high magnification power. Copper alloy poles embedded thread is easy to install and maintain and ensure ultra-high current-carrying capacity. Unique wear wall welded seal of quality to ensure the transmission of high-current welding between the batteries. Enhanced flame retardant polypropylene (L94.V028% LOI) shell and cover special designed to strengthen the protection of the battery casing also enhances the cooling capacity, and to avoid battery bulging deformation and meet safety requirements. DEKA 8G series VRLA batteries using the most advanced colloidal technology, designed for frequent deep discharge, charge and discharge cycle applications, providing excellent deep discharge cycle performance.
