AGM Batteries: A Detailed Explanation of What They Are

What is an AGM Battery?

An AGM battery is a type of lead-acid battery that utilizes a special absorbent glass mat to separate the plates and hold the electrolyte. This unique design offers several distinct features. The glass mat is highly porous, allowing for efficient gas recombination. This means less water loss during operation compared to traditional flooded lead-acid batteries. It also provides enhanced resistance to vibration and shock, which is particularly beneficial in automotive and some deep cycle applications where the battery may be exposed to movement or rough conditions.

Pros of AGM Batteries for Deep Cycle Applications

Deep Discharge Capability

AGM batteries excel in their ability to handle deep discharges. They can be repeatedly discharged to a significant extent without major negative impacts on their performance or lifespan. This makes them highly suitable for applications like solar energy storage systems. In these setups, the battery often needs to provide power during extended periods when the sun isn't shining enough for immediate recharge, and the AGM battery's deep discharge tolerance ensures reliable operation.

They are spill-proof

Unlike the traditional lead-acid batteries that freely flood their electrodes, AGM batteries have glass mats that prevent this. Additionally, it is the function of these glass mats to avoid spillage. Rather than absorbing the electrolyte, the glass mats work by holding the electrolyte in place, preventing it from spilling over, even when the battery is placed in odd positions.

They have a high-power output.

Because of the way that they are designed, the AGM batteries have minimal internal resistance. This, therefore, enables them to provide sufficient bursts of power when necessary, such as when one needs to start a battery. Due to this feature, these batteries respond better to loading than any other battery on the market.

They have a short charging time.

AGM batteries, compared to flooded batteries, charge quickly. When compared to flooded batteries of a similar capacity, the charging rate can reach five times faster with the same power source.

 They have a longer lifespan

AGM batteries have a longer lifespan than traditional flooded batteries. Moreover, not only do they serve for a more extended period when they perform the same tasks, but they also last longer when they are not in active use. This is because self-discharging is minimized in these batteries, unlike other types of batteries, which is a huge problem. This ensures that one does not have to keep charging them after an extended period of inactivity.

They are durable.

These AGM batteries were originally designed to serve the aircraft industry. This means that they have a sturdy design, one that can handle conditions of intense vibrations, just like those in military and commercial aircraft. Because of this property, they are a favorite for high-end motorcycle riders and race car drivers. The sandwich construction method adopted in their design ensures that their internal components do not fall apart. Moreover, they are invulnerable to the subsequent wear and tear that may result from frequent and continuous vibrations. Furthermore, they can withstand extreme temperature variations.

They are unlikely to build up sulfation

Sulfation is the property of lead-acid batteries, where there is a gradual accumulation of lead sulfate crystals in the cells. In most cases, it is the cause of failure in lead-acid batteries. Sulfation mostly occurs when the battery is not fully charged, and thus the crystals continuously build up on the plates. When this process goes out of hand, it prevents the efficient conversion of chemical to electrical energy. Therefore, for other types of lead-acid batteries, it is essential to charge them every six months to prevent sulfation. However, in AGM batteries, sulfation is significantly reduced. Therefore, they can be stored for extended periods without needing a recharge.
