The product features good corrosion resistance grid made of special lead-calcium alloy grid layout optimization depict cut plate drop, low self-discharge rate, the number of long battery life. Special plates active material formulations, high-current discharge function and high charge acceptance to apply to the use of high current demand shock discharges. Separator with high porosity and low resistance, corrosion resistance, high-quality AGM separator, high-rate discharge function well. Electrolyte selection of high-purity electrolyte progress utilization of active material, reducing the battery self-discharge. Valve retardant ABS material, layout depicting common, open and close the valve pressure accurately to ensure the safety and secure. Battery compartment cover made of flame-retardant ABS material, high strength, corrosion resistance, shiny appearance. Pole embedded with large diameter copper, progress can load, internal resistance. Pole with two sealed battery cover chosen layout, climb the pole to prevent acid. Single cell from a single cell constitution (the difference in the internal battery in parallel), make sure that the single cell battery electric power SORENSEN SORENSEN batteries offer.
