The valve-regulated lead-acid battery (VRLA) also known as the cathode absorption lead-acid battery, is a high-tech lead-acid battery that has been created in the last 10 years. It doesn’t require acid and water for maintenance because it can keep a valve-controlled seal during operation. Additionally, because no acid mist is released, there is no environmental pollution or equipment corrosion. The battery can be positioned to save space on the floor by being installed vertically, horizontally, or within building blocks. As a result, the VRLA battery attracted a lot of interest both domestically and internationally and was steadily promoted and used, particularly in industrial batteries. According to foreign statistics, valve-regulated batteries make up roughly 80% of fixed and floating batteries in the US and Europe.
The lifespan of valve-regulated sealed lead-acid batteries is at least fifteen years, and they don’t require constant water addition. The battery’s sealed design avoids acid leakage, protecting the environment and ensuring safety.
It is widely used in alarm and evacuation systems, safety emergency lights, power systems, UPS backup power supplies, hydropower stations, thermal power plants, national military communications, etc.
Its practical application can be classified into two categories:
- Motive power
It is commonly used for automobiles, trucks, forklifts, and railroad locomotives for railroads. According to figures, sales in this region amounted to 40% of total sales in 1977.
- Stationary power
It is mainly used for electronic and medical equipment, telephone communication, uninterruptible power supplies (UPS), security alarms, switch control, emergency lighting, etc. This region accounts for 60% of sales.
Characteristics of valve-regulated lead-acid batteries
The valve-regulated sealed lead-acid battery’s negative electrode has a larger capacity than its positive electrode, so when the positive electrode gas is released in the later stages of charging, it will recombine with the released gas to form water again rather than hydrogen. The flow of oxygen discharged from the positive electrode to the negative electrode to generate water is accelerated using a new type of ultra-fine glass fiber separator. Additionally, the separator features a powerful adsorption function that prevents electrolyte overflow caused by dumping the battery. A premium alloy increases the gas’s overpotential and significantly lowers its release. The equipped charger is used to charge the valve-regulated lead-acid battery, which requires a charging current within the charging voltage range and maintains the voltage at the rated value.
The Bottom line
The valve-regulated lead-acid battery developed in the last decade and doesn’t require maintenance. This battery attracted a lot of interest both domestically and internationally due to its valve-controlled seal and its long lifespan. Moreover, it can be installed vertically, horizontally, or within building blocks and is widely used in alarm and evacuation systems, safety emergency lights, backup power supplies, hydropower stations, thermal power plants, national military communications, etc.
