What is OPzV battery?

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 ℃.

What is tubular OPzV battery?

In a broad sense, the difference between tubular colloidal battery and conventional lead-acid battery is not only that the electrolyte is changed into gelled form. For example, the non-condensable solid aqueous colloid belongs to the colloid battery from the perspective of electrochemical classification structure and characteristics. Another example is that polymer materials are attached to the grid, commonly known as ceramic grid, which can also be regarded as the application characteristics of colloidal battery. Recently, a targeted coupling agent has been added to the plate formula in the laboratory, which has greatly improved the reaction utilization rate of the active substances in the plate. According to the non-public data, it can reach the specific energy level of 70wh/kg by weight. These are all examples of industrial practice at this stage and the application of colloidal cells to be industrialized. The difference between tubular colloidal battery and conventional lead-acid battery is from the initial understanding of electrolyte gelling to the study of electrochemical characteristics of electrolyte infrastructure, as well as the application and promotion in grid and active substances. Its most important feature is that it uses a small industrial cost to produce a better battery along the 150-year-old lead-acid battery industrial path. Its discharge curve is straight, its inflection point is high, its specific energy, especially its specific power, is more than 20% larger than that of conventional lead-acid batteries, and its life is generally about twice longer than that of conventional lead-acid batteries. Its high temperature and low temperature characteristics are much better.
