DKOPzV-420-2V420AH SEALED MAINTANANCE FREE GEL TUBULAR OPzV GFMJ BATTERY

1. Contact surface treatment
The surface of the tank cover, shell and pole of the battery is often contaminated by sweat, oil, dust, etc. In addition, there are release agents on the surface of ABS, PP or recycled plastic. During the use of the sealant, the ABS shell is directly cleaned with organic solvent (acetone) and sealed after drying.

2. Proportioning
The mixing ratio of two-component epoxy resin AB adhesive is determined according to the reaction mechanism. Too much deviation of the mixing ratio will lead to incomplete curing of a certain component or greatly reduce its bonding strength. The correct mixing method is to fully mix the rubber according to the weight ratio rather than the volume ratio (the error is not more than 3%). The viscosity of adhesive A is very high and it is difficult to stir evenly when the ambient temperature is low. Just preheat it to (about 30 ℃) to reduce its viscosity, and then mix it with adhesive B. At this time, it is easier to stir evenly. At the same time, it is also important to fully stir evenly. If the mixing is not sufficient when the mixing ratio is accurate, it will often appear that the local drying or adhesion will occur, and the result is that the bonding performance and acid resistance performance can not meet the requirements completely, It is recommended to use a machine to stir when in use, and scrape the glue adhering to the inner wall of the mixing container and stir it again during the mixing process to ensure that all glue can be fully mixed.

Parameter

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 ℃.

Product characteristics

1. Pole plate: the positive plate adopts tubular pole plate, which can effectively prevent the falling of live materials. The positive plate framework is made of multi-component alloy die-casting, with good corrosion resistance and long service life. The negative electrode plate is a paste type electrode plate. The special grid structure design improves the utilization rate of live material and the discharge capacity of large current, and the charging acceptance capacity is strong.

2. Battery tank: It is a SAN transparent tank, with corrosion resistance, high strength and beautiful appearance. The internal structure and state of the battery can be directly observed through its transparent tank

3. Terminal sealing: the die-cast lead base post with embedded copper core has higher current carrying capacity and corrosion resistance. The pole sealing structure can effectively eliminate the pressure caused by the pole plate elongation in the later period, avoid leakage, ensure the reliability of the pole sealing, and greatly improve the service life of the battery

4. Anti-acid plug: special funnel-shaped anti-acid plug is used, which has the function of filtering acid mist and flame retardant, and is convenient for direct measurement of electrolytic density and temperature, safe for use and convenient for maintenance
