What is an AGM Battery?

At Yuasa, we talk a lot about AGM batteries. But what does AGM actually mean? In this quick guide, we will cover some of the basics about AGM batteries, including what sets them apart from conventional style batteries and some of the advantages of choosing an AGM battery for your vehicle. AGM stands for Absorbent Glass Mat and is an advanced type of lead acid battery that is sealed, spill-free, and maintenance-free.

What is the Difference Between Conventional and AGM Batteries?

Conventional batteries are sometimes called “flooded” because they contain electrolyte that moves freely inside the battery encasement. This design used to be the standard style of lead acid battery, but has since lost popularity in favor of sealed AGM batteries. While conventional batteries are still the most cost-effective style of lead acid batteries, they often have a shorter lifespan and require regular maintenance.

What are the Advantages of AGM Batteries?

AGM batteries hold their charge well and are less likely to sulfate when compared to regular wet cell batteries (conventional battery). Because of this, they are a great choice for vehicles that are not used daily. Because the liquid electrolyte flows freely inside conventional batteries, they must be mounted and stored upright to prevent leakage. AGM batteries, on the other hand, can be mounted in any orientation because the liquid is sealed inside the battery. Another advantage of the electrolyte being suspended inside the battery is that it is more resistant to vibration, which is especially important for ATVs or other vehicles that operate on uneven surfaces.

Whether you’re hoping to replace your existing battery or are purchasing a new battery for the first time, it’s important to understand the difference between AGM and conventional batteries. If you use your vehicle every day and are looking for a cost-effective option, a conventional battery may be right for you. However, if you need a battery for your ATV, snowmobile, or other powersports vehicle that you ride only seasonally, an AGM battery is likely the best option.
