What model of battery is AGM?

AGM batteries are ultra-fine glass fiber batteries. AGM (Absorbent Glass Mat): Refers to Absorbent Glass Mat technology. AGM batteries are an advanced technology battery that uses absorbent glass mat technology, making them the most technologically advanced batteries available today. Compared to batteries of the same specifications, AGM batteries have the following advantages due to their technology: cycle charging capacity is more than 3 times higher than lead-calcium batteries, with a longer service life and cycle. They have higher electrical capacity and stability throughout the battery's entire life cycle. They offer more reliable and durable performance in low temperatures. They reduce the risk of accidents caused by overheating and minimize environmental pollution risks (due to 100% sealed acid). They are maintenance-free, environmentally friendly, and reduce deep discharge. AGM batteries are ultra-fine glass fiber batteries, while EFB batteries are start-stop batteries. The structure of AGM batteries is different from that of ordinary batteries, offering better performance and a longer service life. However, AGM batteries are more sensitive to high temperatures, so they are best placed in the car's trunk, while EFB batteries are suitable for placement in the car's engine compartment.
The full name of an AGM battery is Absorbent Glass Mat battery, which refers to a special type of lead-acid battery that uses a glass fiber mat to absorb the electrolyte. I remember it is particularly suitable for modern vehicles, especially those with start-stop systems, as it can provide high-power current output during frequent starts, something ordinary lead-acid batteries struggle with. Its sealed internal design ensures the electrolyte is absorbed by the glass fiber, preventing leaks or spills, making it very safe and reliable. I've seen many vehicle owners use it in SUVs or RVs, with a typical lifespan of over 5 years, and it's mostly maintenance-free—no need to add water, and it can withstand deep discharges without damage. If the vehicle sits idle for too long, periodically charging it with a smart charger will help maintain performance; otherwise, it may degrade. Overall, AGM is a high-performance option, though slightly more expensive, and selecting the correct voltage and capacity to match your vehicle is crucial.
