At Yuasa, we talk a lot about AGM batteries. But what does AGM stand for? AGM means absorbent glass mat and refers to the fine glass fiber separator between the positive and negative plates that helps absorb all the battery acid. AGM Batteries are advanced lead-acid batteries.
Below, we will expand on that answer, so you know what you need to know to choose the right battery type for you.
What You Need to Know: AGM Battery
We’ve already given the most straightforward answer to the question, but there is more to a complete response when asked, “what is an AGM Battery.” AGM or Absorbent Glass Mat batteries are advanced maintenance-free lead-acid batteries designed to resist spilling acid and reduce water loss during usage. In addition, AGMs provide superior power, as well as vibration resistance in today’s high-electrical demand vehicles due to their optimized cell design and compression.
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 and disadvantages of choosing an AGM battery for your vehicle.
What is the Difference Between Conventional and AGM Batteries?
Conventional batteries may be referred to as “flooded” because they contain electrolyte that moves freely inside the battery encasement. This design used to be the standard style of lead-acid batteries but has since lost popularity in favor of sealed AGM batteries.
While conventional batteries are still the most cost-effective 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 batteries types). Because of this, they are an excellent choice for vehicles that require off-season storage.
AGM batteries can be mounted in more flexible orientations than conventional batteries because the liquid is sealed inside the battery. Because the liquid electrolyte flows freely inside conventional batteries, they must be mounted and stored upright to prevent leakage.
Another advantage of the electrolyte being absorbed and held by a separator suspended inside the battery is that it is more resistant to vibration, a vital plus for ATVs or other vehicles that operate on uneven surfaces.
So, if you need a battery for your ATV, snowmobile, or other Powersports vehicle that you ride seasonally, an AGM battery is likely the best option.
When is a Conventional Battery Best?
There aren’t many disadvantages to choosing an AGM battery. However, whether you’re hoping to replace your existing battery or purchase a new battery for the first time, it’s essential to understand the difference between AGM and conventional batteries.
Conventional batteries, as mentioned above, are still more cost-efficient for a daily driver than AGM batteries. If you use your vehicle every day and are looking for a cost-effective option, a conventional battery may be correct for you. However, conventional batteries offer an increased chance of battery spills or leaks.
AGM holds a clear advantage in any seasonally used vehicle, including motorcycles in areas where the climate makes them seasonal equipment.
Please also note that a conventional battery cannot simply be replaced with an AGM battery. If your vehicle originally had a conventional battery, the vehicle rectifier or regulator design is for a conventional battery, and it could cause an issue with the replaced AGM battery. The opposite way as well.
What are the Most Common Uses?
AGM Batteries most often go in high-electrical demand vehicles and seasonally used vehicles like ATVs, Snow Mobiles, UTVs, and Powersports vehicles that require higher power, acid spillage resistance, and vibration resistance. If you need lots of power, the ability to store your vehicle during the off-season, and are looking for a virtually maintenance-free battery, then an AGM is a perfect choice.
