Definition of AGM Type Battery

An AGM (Absorbent Glass Mat) type battery is a specialized type of lead-acid battery that uses a unique design to enhance its performance and reliability. This type of battery is commonly used in a variety of applications, from automotive to marine, due to its exceptional durability and ability to deliver consistent power.

The AGM technology utilizes a fiberglass mat placed between the battery plates, which is soaked with electrolyte fluid. This mat acts as a separator and immobilizes the electrolyte, preventing it from freely flowing. Unlike conventional flooded lead-acid batteries, AGM batteries are designed to be completely sealed, preventing any leakage of acid or electrolyte.

The design of an AGM battery allows for a higher power-to-weight ratio compared to traditional flooded batteries. This means that AGM batteries can provide more power while being lighter and more compact in size. Additionally, AGM batteries are known for their low internal resistance, enabling them to deliver a higher current and perform better in applications that require a quick discharge.

Another defining characteristic of AGM batteries is their ability to function in various orientations. They are not restricted to being mounted upright, making them suitable for use in unconventional spaces or in equipment that experiences vibrations or shocks.

Furthermore, AGM batteries are maintenance-free, eliminating the need for periodic water refilling. They also have a longer lifespan compared to traditional flooded batteries, thanks to the efficient retention of the electrolyte within the glass mat separator.

Overall, AGM type batteries offer numerous advantages in terms of efficiency, reliability, and practicality. Their unique design and technology make them an excellent choice for a wide range of applications, where reliable and consistent power delivery is essential.
