D King OPzV battery, also named GFMJ battery The positive plate adopts tubular polar plate, so it also named tubular battery. The nominal voltage is 2V, the standard capacity normally 200ah, 250ah, 300ah, 350ah, 420ah, 490ah, 600ah, 800ah, 1000ah, 1200ah, 1500ah, 2000ah, 2500ah, 3000ah. Also customized capacity are produced for different applications.Structural characteristics of D King OPzV battery: 1. Electrolyte: Made of German fumed silica, the electrolyte in the finished battery is in gel state and does not flow, so there is no leakage and electrolyte stratification. 2. Polar plate: The positive plate adopts tubular polar plate, which can effectively prevent the falling off of living substances. The positive plate skeleton is formed by multi alloy die casting, with good corrosion resistance and long service life. The negative plate is a paste type plate with a special grid structure design, which improves the utilization rate of living materials and the large current discharge capacity, and has strong charging acceptance capacity.
3. Battery shell Made of ABS material, corrosion resistant, high strength, beautiful appearance, high sealing reliability with the cover, no potential leakage risk. 4. Safety valve With special safety valve structure and proper opening and closing valve pressure, water loss can be reduced, and expansion, cracking and electrolyte drying of battery shell can be avoided. 5. Diaphragm The special microporous PVC-SiO2 diaphragm imported from Europe is used, with large porosity and low resistance. 6. Terminal Embedded copper core lead base pole has greater current carrying capacity and corrosion resistance. Key advantages compare to normal gel battery: 1. Long life time, floating charge design life of 20 years, stable capacity and low decay rate during normal floating charge use. 2. Better cycle performance and deep discharge recovery. 3. It is more capable of working at high temperature and can work normally at - 20 ℃ - 50 ℃.

OPzV is O-Ortsfest (fixed), PZ-PanZerplatte (tubular plate), V-Verschlossen (sealed). That is, OPZV is originated from Germany and is the abbreviation of this type of battery. Main characteristics of OPZV battery Based on the definition of OPZV battery, it is concluded that OPZV colloidal battery must have the following characteristics before it can become a real OPZV tubular colloidal battery. 1. Service life of OPZV colloid battery: the design floating charge life of conventional battery is more than 18-20 years; 80% DOD cycle life more than 1500 times. 2. Positive plate of OPZV colloid battery: the positive plate mainly consists of three parts, grid, bushing and active substance. The plate is tubular. 3. Negative plate of OPZV colloid battery: the negative plate mainly consists of two parts, grid and active substance. The shape of the plate is a plane plate. 4. Electrolyte of OPZV colloid battery: the electrolyte mainly consists of two parts, sulfuric acid and silicon colloid. 5. Battery shell of OPZV colloid battery: The battery shell usually uses flame-retardant ABS. 6. Terminals of OPZV colloid battery: copper terminals are used to enhance conductivity.
