An AGM battery, or Absorbent Glass Mat battery, is an advanced type of lead- acid battery distinguished by its use of a fine glass fiber mat separator that absorbs and holds the battery acid (electrolyte) between the positive and negative plates. This design prevents the acid from freely flowing inside the battery, making it spill-proof and resistant to vibration

. Key characteristics of AGM batteries include:

• Sealed and Maintenance-Free: The electrolyte is absorbed into the glass mat, so AGM batteries are sealed and do not require water refilling like traditional flooded lead-acid batteries

• Valve-Regulated Lead-Acid (VRLA) Type: They have safety valves to release excess gas but promote recombination of gases inside, minimizing water loss and enhancing safety

• Superior Performance: AGM batteries provide higher power output, faster charging, better vibration resistance, and longer cycle life compared to conventional flooded batteries

• Versatile Mounting: Because they are sealed and spill-proof, AGM batteries can be mounted in any orientation without risk of leakage

• Applications: Commonly used in modern vehicles (especially with start-stop systems), boats, motorcycles, off-grid power systems, and backup power due to their reliability and durability

In summary, an AGM battery is a premium, sealed lead-acid battery that uses an absorbent glass mat to contain the electrolyte, offering enhanced safety, performance, and maintenance-free operation compared to traditional flooded lead-acid batteries
