The positive electrode adopts a tubular plate, the negative electrode is a plate structure, the separator is imported PVC-SiO2 material, and the electrolyte is a colloidal electrolyte. The floating charge service life is up to 20 years (20°C). Low, the charging can be resumed immediately after 24 hours of deep discharge, making the capacity reach 100% of the rated capacity. It is especially suitable for the environment with large temperature difference and unstable power grid, or the renewable energy storage system that is in a state of power deficit for a long time.

Battery performance characteristics
• Colloidal electrolyte, no liquid stratification, no leakage 
• Tubular positive plate design, which can effectively prevent the shedding of active materials
• Adopt special microporous PVC-SiO2 separator 
• No maintenance during the entire service life 
• Low self-discharge Rate
