The performance of Sealed Agm Battery will be affected at highe

  •   Sealed AGM Battery was first developed in the 1970s. It uses glass fibers to woven into a very thin cushion layer that is saturated with sulfuric acid and then placed between two plates. This immediately solved various problems in the older design, which is now called Flooded Lead Acid (FLA). Because these valve-regulated batteries are leak-proof, they can be transported without being restricted by any hazardous materials. These plates can be flattened to make it look like a standard FLA battery in a rectangular case, Sealed Deep Cycle Battery, or it can be wound in a cylindrical battery.

      This technology received attention in the 1980s as SLA batteries for UPS, military vehicles, and aircraft to improve reliability and reduce weight. The following are some significant advantages of AGM batteries:

      If the shell cracks or breaks, the acid will stay in the cushion and will not leak out.

      These batteries can be installed at any angle because the design ensures that the plates are always in full contact with the electrolyte.

      The mat is essentially an indispensable part of the battery structure, which can hold the lead plate in place and prevent any bending. Even if the plates do bend, the mat can prevent them from touching each other.

      The internal resistance of AGM batteries is also very low, which means that they have a relatively long service life (even in deep cycles) and can provide large currents on demand. In addition, AGM batteries have zero-maintenance functions, are much lighter than full-liquid lead-acid batteries, and have excellent electrical reliability. Since they are not easily sulfated, they can also be stored for a long time without paying. In addition, the battery has a low self-discharge rate and can withstand low temperatures well.

      The list of advantages doesn't stop there! AGM battery also has excellent deep cycle ability, charging speed is 5 times faster than FLA battery. They also perform well in the depth of discharge (DoD) sector. Although overflowing lead-acid usually has a specified DoD of 50%, AGM batteries provide approximately 80% of the DoD.

      Because AGM batteries are relatively light and have good vibration resistance, they are often used in automobiles and airplanes. In addition, its unique design means that the chance of acid splashing in the event of a collision or accident is relatively low. AGM batteries also have excellent cold-weather performance, which makes them suitable for marine, robotics, and RV applications.

      However, like all other types of batteries, AGM batteries have their disadvantages. First, their performance will be affected at higher temperatures. In fact, many manufacturers recommend stopping charging if the temperature of the battery cell exceeds 49°C (120°F). AGM batteries are also sensitive to overcharging.
