¡El SENRY Battery es de alta calidad!Features of Sanrui battery CGT series: • ¡El high-porosity PVC-SiO2 separator created by the world-renowned colloidal battery separator manufacturer has superior anti-oxidation performance, making its life span over 30 years; the porosity is 74%, the acid discharge is 180 mL/m2, and the pore size is mostly Between 1 and 10 μm, the short circuit of lead dendrites is effectively prevented; • Strong recovery ability from deep discharge; 100% capacity recovery can be achieved if electricity is not replenished in time within 30 days, so it can be used in conditions where electricity cannot be replenished in time, such as solar photovoltaic systems with changing weather conditions. • ¡El unique lead-calcium-tin-aluminum grid deep cycle plate formula and casting process can improve the deep cycle life of the battery and be environmentally friendly and energy-saving. • ¡El liquid-rich design adopts low-density colloidal electrode liquid, which effectively protects the positive grid and prolongs the life of the battery to the greatest extent.
