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 OPZV battery?

OPZV battery is a deep cycle battery, which generally refers to the sealed maintenance free tubular gel lead-acid battery in the ABS container. The electrolyte in OPZV battery uses thixotropic silica gel for gel. These batteries have a battery voltage of 2 volts and are connected together to obtain the required voltage. They are usually used as backup power for solar cell applications, power stations and substations, oil and gas, nuclear energy, hydropower and thermal power generation facilities, and backup applications. The electrolyte is in the form of gel, and the battery will not leak.

There are two main methods for acid fixation:
Fix acid in place with absorbent glass pad, called AGM VRLA battery.

On the other hand, adding fine silicon powder to make gel, such as gel battery, although these two methods are very different, they both achieve the purpose of fixation. They also provide the additional benefit of recombining the gas released during charging to reform the water, thus eliminating the need for the water-adding maintenance procedure of the liquid-rich lead-acid battery mentioned above.

Among the two methods, the use of silica gel as the electrolyte is generally considered to be a good solution for the design of deep discharge gel batteries. This is mainly due to two reasons: the use of electrolyte during condensation allows the use of tubular positive plates, which is considered to provide good deep cycle performance for lead-acid batteries. The second reason is to avoid acid delamination associated with deep discharge and limited voltage charging without outgassing. If you have deep cycle requirements in solar cell applications, these are significant advantages of OPZV battery technology. What is colloidal battery technology?

How does this combination of tubular plate and gel electrolyte work? To understand, we must look at several elements that affect the characteristics of the battery. They are electrolytes fixed as GEL to ensure that they will not overflow and that the hydrogen and oxygen released during charging (kept in the battery under pressure) can recombine to form water. The benefits of immobilization are expanded. It can prevent the formation of acid layers with different densities in cells, called acid layering.

In the design of liquid-rich battery and sometimes AGM VRLA, the gravity acid with high density generated on the electrode plate during charging will fall to the bottom of the battery, leaving weak gravity acid at the top. In this case, the battery will fail prematurely due to battery sulfation, premature capacity loss (PCL) and grid corrosion. DKING has a tubular gel battery factory imported from Germany, and uses imported gaseous silica to provide the battery with an uncompromising service life and performance.
