Our EV lead acid series is designed with high quality grid alloy enables the grid with features of anti-corrosion, low gas emission and excellent deep cycle performance, as well as high density and special deep cycle lead paste prescription is adopted to ensure extra-long cyclic life. The cycle life may reach 600+ cycles @80% DOD High Capacity and High Energy Density: Rocket EV Series is designed with adequate active material and higher electrolyte density to increase the battery's capacity with certain dimension and weight, so as to keep the battery with high energy density to be compatible with most of the electric vehicles. High Reliability and Safety: High strength ABS Battery container and lid, perfect safety valve design and high strength and excellent large current electro-conductivity copper terminal design are adopted to ensure the Rocket EV Series with high reliability and safety at extreme conditions. High Environmental Adaptability: Rocket EV Series adopts special fumed silica Gel in electrolyte and special Gel type separators to prevent electrolyte stratification. This can significantly improve the battery's service life and environmental adaptability Non-Cadmium Design, Environment-Friendly: Rocket Battery has adopted internationally leading technology- container formation non-cadmium production technology, which is the leading position in the industry. It helps to save energy 28.5%, save water 90% and non-discharge of wastewater.
