High Quality: The electrical storage batteries is a sealed valve-regulated lead-acid battery, which is a rechargeable battery based on AGM (absorbent glass fiber board) technology or colloidal GEL electrolyte. Because of its structural characteristics, it can be installed in any direction and has superior high current Discharge characteristics and long service life.

Safe Sealing: During normal operation, the electrolyte will not leak from the battery's terminals or case; no free acid A special absorbent separator keeps the acid in, there is no free acid inside the battery, so the battery can be placed anywhere Position; leaking system, when the internal pressure of the electrical storage batteries exceeds the normal level, the VRLA battery will release excess gas and automatically reseal it to ensure that there is no excess gas in the electrical storage batteries.

Easy Maintenance: Due to the unique gas recombination system that converts the generated gas into water, no water needs to be added during the use of electrical storage batteries, which is easy to maintain.

Measures To Achieve Sealing：(1) Choose high-porosity AGM separators with a porosity above 93% to provide channels for oxygen recombination.

(2) Quantitative acid injection is adopted, so that after the glass wool separator absorbs the electrolyte, 5-10% of the porosity is still not filled with the electrolyte, so the electrical storage batteries is also called a barren battery.

(3) Excessive negative electrode active materials, the capacity ratio of positive and negative plates is generally 1:1.1~1:1.2, so that after the positive electrode is fully charged, the negative electrode is still not fully charged to prevent hydrogen from being precipitated at the negative electrode. cannot be compounded.

(4) For the tight assembly of the battery cluster, the cluster pre-compression technology is adopted to press the assembly between 40-60Kpa to ensure good contact between the AGM separator and the surface of the positive and negative plates, because the electrolyte of the VRLA battery is mainly separated by AGM board provided.

(5) High-purity Pb-Ca-Sn-Al antimony-free grid alloy, because Pb-Ca alloy has higher hydrogen evolution overpotential than Pb-Sb alloy, which can reduce the possibility of hydrogen evolution due to grid corrosion.

(6) Safety valve with stable and reliable opening and closing valve pressure. The standard of communication electrical storage batteries requires opening valve pressure of 10-35Kpa and closing valve pressure of 3-15Kpa. The pressure of opening and closing valve is relatively close, which can reduce gas discharge and water loss.

(7) The constant voltage and current limiting charging method is used. Electrical storage batteries are more sensitive to overcharging. Overcharging will accelerate the current damage. Constant voltage and current limiting charging can prevent overcharging and thermal runaway.

Versatile: This electrical storage batteries are versatile and can be used in power tools, emergency lights, UPS, electric wheelchairs, computers and communication equipment, etc.
