OPzS battery adopts a tubular plate, the grid of positive plate is Pb-Sb multi-alloy, the negative plate is a plate electrode plate, the separator is porous rubber and PVC, the electrolyte is a liquid-rich type, the battery shell material is a transparent AS shell, and a special electrode plate The structure greatly improves the corrosion resistance, and the design life can reach 20 years. It has excellent high-current discharge characteristics and charging acceptability. There is enough electro-hydraulic during discharge. The internal resistance is extremely low, and the battery is easy to maintain.
