What kind of battery is the Agm sealed lead acid battery?

AGM sealed lead-acid battery is a kind of valve regulated sealed lead battery with glass fiber separator (AGM), also known as VRLA battery. This kind of battery uses pure sulfuric acid aqueous solution as electrolyte, and most of the electrolyte is adsorbed in the glass wool partitions (AGM), only a very small amount of electrolyte exists in the bottom of the battery, and the thickness of the pole plate is thicker, so compared with the ordinary batteries, AGM batteries have a longer service life, higher capacity reliability, and stronger low temperature reliability. In addition, the acidic solution of AGM battery is 100% sealed, so there is no gas emission when working, which is less destructive to the natural environment, and at the same time, there is less potential danger of battery explosion in case of accidents.


Usually AGM batteries have a lifespan of 4-6 years, and from the point of view of the market use, AGM batteries are sealed batteries and do not require maintenance; therefore, there is no need to check the battery's health status continuously; this is the advantage of AGM batteries versus lead-acid batteries. In addition, AGM batteries are spill-proof because the absorption of glass fibers absorbs sulfuric acid, preventing the battery from spilling and ensuring better performance. In addition, these batteries are not susceptible to environmental conditions such as heat and cold. They also charge up to five times faster than lead-acid batteries, making them more popular among agm batteries versus lead-acid batteries. On the downside though, when it comes to solving the problem of Agm sealed lead acid batteries vs lead acid batteries, agm batteries are sensitive to overcharging. This is because the battery is completely sealed and when overcharged, there is no way for the heat generated to escape. In addition, the electrolyte content is used up and since it is irreplaceable, the battery packs up. Flooded lead-acid batteries, however, are unsealed, allowing heat to escape; the liquid content can also be replaced. They can withstand overcharging better.

AGM batteries typically have a life expectancy of about four to six years, providing a longer life than regular batteries. Meanwhile, the charging limit operating voltage of AGM batteries is 14.5 volts, so you need to choose an AGM-specific charger when selecting a charger.AGM batteries are usually used in European and American cars, while EFB batteries are mainly used in Japanese cars. Compared with batteries of the same specifications, Agm sealed lead-acid batteries are relatively more expensive, but have a higher cycle charging capacity than lead-calcium batteries, have a longer service life, and are more reliable in low-temperature performance, while at the same time, they have a higher stability of electric capacity throughout the entire service life cycle

Market Observations and Outlook:

AGM sealed lead-acid batteries are used in a wide range of scenarios, which mainly include uninterruptible power supply, electronic energy system, emergency standby power supply, emergency lights, railroad signals, aviation signals, security systems, electronic instruments and equipment, power supply for call systems, DC power supply and automatic control systems. In addition, AGM batteries are also widely used in the automotive industry, especially in European and American models.

With the continuous progress of science and technology and the rise of new energy market, the market demand of AGM sealed lead-acid batteries is also increasing. On the one hand, with the growing concern for environmental protection and sustainable development, the traditional lead-acid battery industry is developing in a more environmentally friendly and sustainable direction. AGM sealed lead-acid batteries, as a new type of lead-acid batteries, have higher energy density, longer cycle life and better safety, and therefore have received widespread attention and application. On the other hand, with the expanding new energy market, especially the rapid growth of the electric vehicle market, the demand for AGM sealed lead-acid batteries as energy storage solutions is also increasing. In addition, with the popularization and application of 5G, IoT and other technologies, the market demand in data centers, telecommunication equipment and other fields is also increasing, which also provides a broader market space for AGM sealed lead-acid batteries.

AGM sealed lead-acid batteries are used in a wide range of scenarios, the market demand is increasing, and there is still a great potential for future development. At the same time, with the strengthening of environmental regulations and intensifying market competition, AGM sealed lead-acid battery enterprises need to continuously improve product quality, reduce costs and expand new application areas to adapt to market changes and demands. Overall, AGM sealed lead-acid battery is a kind of battery with excellent performance, long service life, safety and reliability, which is widely used in automobile, UPS power supply, telecommunication equipment, data center and other fields.
