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 ℃.
