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 are the advantages, disadvantages and uses of tubular and pull lead acid batteries?

Tubular plates have some advantages, such as good deep discharge performance, long battery life, and can be made into larger capacity batteries; However, there are also some fatal disadvantages, such as complex production process (high cost), low energy density (low cost performance), low charging current (slow charging), and large changes in the size of the plate (often breaking the shell).

Compared with tubular plate, grid plate has some disadvantages, such as short life (cycle life and floating charge life are much shorter, because the active material is easy to fall off), limited capacity of battery that can be made (mainly not too high in height), poor performance of small current, etc., but the advantages of current VRLA are very attractive: first, simple process and low cost; Second, it has strong charging capacity with large current and can charge quickly; Third, the energy density is high, which is mainly for tubular plates. In fact, the energy density of lead storage is very low in the battery; Fourth, it is safe. Unless there is impact or high temperature, the shell will not break, because the plate will not change in its life cycle.

With the above characteristics, their respective uses are also obvious: there are two main applications of tubular plates. First, the floating charge life is very long in small current and long-life applications, such as solar energy, wind energy and other clean energy; Second, it can be used with diesel engines in the absence of mains power supply. For example, the communication base station can be used with diesel engines for deep discharge cycle, and the cycle life is quite long; The grid plate is applied to all scenarios except the above scenarios, such as car startup, UPS, communication, electricity, and even power supply for electric vehicles.
