 ● Standard
Regarding GFMJ series valve-regulated lead acid battery (OpzV battery), there are 17 specifications from 200 to 3000Ah in total, the performance parameters reach or partially exceed German Standard DIN 40742.
● Application
Backup power supply for Telecommunication, Railway, Electric Power, Nuclear Power Station, UPS, Emergency Illumination, Vessels and Maritime Affairs etc.; Energy Storage for Photovoltaic System and Wind Electricity Generation System etc.
● Features
The battery electrolyte contains fumed silica and there is no flow, no leakage or no gradation of sulfuric acid. The battery can be put horizontally or vertically. There is no risk of leakage during the utilization and transportation, and it is safe and reliable.
The gel electrolyte is in dilute sol state when being injected. Excessive electrolyte can fill in all the space inside the battery. Under circumstance of high-temperature and overcharge, the battery will not dry out. The gel battery has large heat capacity and good radiation performance. It is not easy to appear thermal runaway. The battery can work under severe environmental conditions.
The positive plate is a tubular plate, which can effectively prevent the active materials from falling off. The positive plate skeleton is made of Pb-Ca alloy through die cast, and the thin and compact crystal grains of alloy ensure good performance of corrosion proof. The negative plate is pasted plate, and the grid is in radial structure, which is favorable for improving the utilization rate of active materials and is favorable for discharging at large current. Pb-Ca alloy is adopted and the voltage of hydrogen evolution is high. Unique lead paste formula enables perfect recovery performance of battery recharging after deep discharging. The battery has strong cycle and duration performance, sufficient capacity and long life.
Adopt PVC-SiO2 separator produced by European AMER-SIL Co., which is with tiny holes and is special for gel battery. The separator has high porosity and low resistance, and the internal resistance of battery is low.
Adopt imported safety valve. The open and close valve has constant pressure and the reliability is high, which can prevent case swelling, breaking and electrolyte dry out.
The ABS case and lids of the battery is imported from Italy, which is sealed with resin imported from Germany, so that to ensure no-leakage and to prevent air leakage.
The terminal is compounding type with inlaid lead copper core. It is processed through die cast and is sealed with imported resin and by imported special equipment. Due to its unique sealed structure of terminal, the seal between case and lid of battery and metal battery terminal is not the direct agglutination between sealant and metal surface, instead, it is the agglutination with the protective sleeve of organic materials and terminal, which makes the seal reliable.
The closed connection soft thread of terminal post can effectively prevent short circuit due to accidents or avoid risk of suffering from electric shock.
