ATV Battery Guide: Lithium vs AGM vs Lead Acid

ATVs use batteries to function and give a long life. But only a few people know about the differences between lithium, AGM, and lead-acid batteries.

Lead acid batteries are the conventional option used in most ATVs. Lithium batteries are a premium option with no liquid, so it’s lighter, more durable, and longer lasting but more expensive. AGM batteries have better vibration control for solid battery life and are maintenance-free.

We have used each of these battery types in the past with our ATVs, so we understand the key differences and which works best. Below we give a complete breakdown, including how each battery works along with the pros and cons of each.

‍ATV Battery Guide: Lithium vs. AGM vs. Lead Acid

One way to ensure an ATV runs confidently and efficiently is by upgrading the battery. This can help riders avoid breaking down or unexpected issues while on the trails.

A few different types of batteries can be used in all-terrain vehicles (ATVs), including lithium, AGM (Absorbent Glass Mat), and lead-acid batteries.

Each type has its own advantages and disadvantages, so it's important to consider your specific needs and preferences when choosing a battery for your ATV.

Lithium Battery

Lithium batteries are becoming increasingly popular in ATVs due to their high energy density and long lifespan. They are also much lighter than other batteries, which can be a significant advantage in increasing ATV speed.

However, they are generally more expensive than other types of batteries, and they may only be suitable for some ATV applications. If budget is not the primary concern, we prefer a compatible lithium battery with our ATV.

They hold a charge longer while in storage, so you rarely need to charge them before using the ATV. This is true even after keeping an ATV stored away for a while.

Another fantastic benefit lithium batteries can offer is their reaction to voltage, current, and temperature changes. There are no performance changes in extreme temperatures, which is crucial for winter ATV riders.

AGM Battery

AGM batteries are more similar to lead acid batteries in that they use lead-based chemistry, but they have a different construction that makes them more resistant to damage and easier to maintain.

AGM batteries are sealed, so they are resistant to leaks and spills and can be mounted in any position. They are also relatively lightweight and have a good lifespan, but they may not be as powerful as other types of batteries.

The great thing about this battery type is the minimal maintenance required when using one. Because they have an absorbent layer, they will discharge slower, requiring less charging and no front-end work.

They are prepacked when purchased, so there is typically no need to fill the battery casing with acid. This is one reason why many beginners opt to use these batteries instead.

Lead Acid Battery

Lead acid batteries are the most common type of battery used in ATVs and are generally the least expensive option. This is usually the standard battery in many ATV models at purchase.

They are relatively heavy and may not last as long as lithium or AGM batteries, but they are reliable and can provide the power you need for your ATV. However, they do also require maintenance which is a concern for some.

The lead-acid battery requires consistent maintenance to function properly. This includes checking and refilling the acid levels, so there is enough acid between the lead plates to run efficiently.

They also don’t come ready to install, which is a major concern for ATV riders with little experience handling batteries. If you plan to use this conventional battery, consult a professional before installing it.

How Long Does An ATV Battery Last?

The lifespan of an ATV battery depends on several factors, including the type of battery, how it is used, and how well it is maintained. Lithium batteries have the longest lifespan, followed by AGM and lead-acid batteries.

Lithium Battery

Lithium batteries can last for many years, depending on how they are used and how well they are maintained.

They are generally considered to be the most durable and long-lasting options compared to other types of batteries, and they can go for several seasons or more without needing to be replaced.

AGM Battery

AGM batteries also have a good lifespan and can generally last for several seasons or more before needing to be replaced. They are sealed and require minimal maintenance, which can help to extend their lifespan.

Lead Acid Battery

Lead acid batteries may last less time than lithium or AGM batteries and may need to be replaced more frequently. Typically, it will last for 1-2 years unless kept safe in storage during the cold.

The lifespan of a lead acid battery can vary depending on how it is used and how well it is maintained, but it is generally shorter than the lifespan of a lithium or AGM battery.

Lithium ATV Battery Pros & Cons

Lithium ATV batteries have several advantages and disadvantages that you should consider when deciding whether they are the right choice for your ATV.
