The company in 1957 started to develop gel batteries. Because there have been sealed gel batteries and a new company for the development of colloidal sunshine sealed battery provides favorable conditions. For over 40 years, they gelled electrolyte formulation of additives and various specialized in the development, manufacture and application of technology and other fields continue to carry out the study and improvement. In-depth study found that gel batteries have low self-discharge resistance, deep discharge performance, long cycle life, floating charge down, float current, low maintenance, easy to maintain, no corrosion, no pollution, no gas to escape, No spills, environmental protection and other features.
