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 ℃.

Relevant knowledge of tubular colloid battery

Principle
It belongs to a development classification of lead-acid batteries, and is the simplest method. Because the electrolyte is colloidal, tubular colloidal battery is often called colloidal battery.

Product characteristics
1. Electrolyte: It should be made of German fumed silica. The electrolyte in the finished battery is in a gel state and will not flow, so there will be no leakage and electrolyte stratification.
2. Pole plate: the positive plate shall be tubular pole plate, which can effectively prevent the shedding of live materials; The positive plate frame is pressed and formed by multiple alloys, so it has high corrosion resistance and long service life. The negative plate is a paste type plate. Due to the special grid structure design, the utilization rate of live material and the discharge capacity of large current have been greatly improved, and the charging acceptance ability is also very strong.
3. Battery shell: ABS material, with corrosion resistance, high strength, beautiful appearance, and high reliability of cover seal without leakage.
4. Safety valve: The safety valve adopts a special structure and applies a suitable opening and closing valve pressure to reduce the loss of water, which can effectively prevent the expansion, fracture and electrolyte drying of the battery shell.
5. Diaphragm: The special microporous PVC-SiO2 diaphragm imported from AMER-SIL in Europe is adopted, which is characterized by high porosity and low resistance.
6. Terminal: embedded copper core lead base pole, which can withstand greater current carrying capacity and has high corrosion resistance.

Technical advantages
1. Self-discharge is very low. It is made of high-quality materials, and the monthly self-discharge rate is less than or equal to 1.5%.
2. Colloidal electrolyte is used, which has large heat capacity and good heat resistance, and can also be used normally in harsh environment (- 40~60 ℃).
3. Excellent cycle performance and strong deep discharge recovery ability.
4. There is no need to supplement water for maintenance, and the gas recombination efficiency is very high.
5. It has a long service life. In the normal floating charge process, it reflects the characteristics of stable capacity and low attenuation rate.
6. Excellent sealing performance, no gas penetration, no pollution to the environment, is an environment-friendly product.
7. Excellent safety performance, special partition, high porosity and low resistance.
8. Copper pole with low internal resistance ensures safe discharge of large current without heating.
9. The concentration distribution of solid gel electrolyte is very uniform, without stratification.
10. The product has high reliability, effective fire retardant safety valve, preventing external open fire or sparks.

Application field
The application fields are very wide: telecommunications, wireless and microwave relay stations, emergency systems, power stations, nuclear power stations, alternating power stations, solar energy, wind energy, large UPS, train signal, marine standby power supply (on board or on shore), process and control plants, standby voltage supply, buoy lighting.
