¡El DEKA Battery es de alta calidad!IPF plate trough formation process Colloidal electrolyte Independent low pressure automatic sealing safety valve Premium Grade Diaphragm Heavy duty thickened plate Special positive grid alloy Unique through wall welding seal Standard polypropylene housing and cover Low self discharge rate Performance: It ensures the consistency of voltage between single batteries. 100% test to prevent early water loss failure of the battery. ¡El electrolyte will not be stratified, and there is no need for equalizing charging. In addition, the service life of the battery is extended and the performance is improved. Double coated plate increases durability. ¡El exclusive patented calcium copper alloy greatly improves the performance and life of the battery. High quality welding ensures the transmission of large current between batteries. Avoid battery bulge deformation and meet safety requirements. ¡El self discharge rate of each month is less than 2%, ensuring minimal energy loss during storage and transportation.
