Best ATV Batteries (Review & Buying Guide) of 2021

ATV is basically an electric and versatile multi-terrain four-wheeler (quad) vehicle that is ridden for fun. And like all-electric vehicles it is powered by a battery. Both the battery and the charging system in an ATV are directly related. It, therefore, plays a huge role in the powering up of the battery. These Batteries for ATVs are also designed to start the engine, save weight, and reduce cost. And because of these features, it makes it possible for them to handle electric loads on the low amp-hour capacity.

Due to the increase in popularity of ATV on the market, the variety of ATV batteries in stores is overwhelming. This gives an ATV owner a variety of batteries to choose from. So before going for ATV battery shopping, you must consider which battery suits your ATV the most. Like they say something that has been started perfectly fine is halfway done.

Types of ATV Batteries

There are two types of ATV batteries, Lead-acid or conventional, and Gel cell also known as AGM (Absorbed Glass Mat) batteries. There are other terms used to describe these batteries but they all refer to these two types.

Lead-Acid (conventional or flooded) Batteries

These types of batteries are sometimes called conventional batteries because they have been around for a long period of time. White or natural is their typical housing color. They are cheap on the market because of their inconvenient features like the removable filler cap. And it’s because of this feature that they are sometimes referred to as “flooded” batteries. The removable filler is removed to refill the plates once submerged in acid and distilled water when the battery runs dry. That’s why you are required to have additional acid to support the plates.

Lead-Acid type of batteries is prone to spillage. Therefore, as a quad user, you are advised to only use this type of battery on the well-paved road. Otherwise, you will shorten the lifespan of both an ATV and its battery. For this type of battery, you are also required to be frequently checking the level of distilled water in the plates so that it doesn’t run dry. This is maintenance-free batteries so if it runs dry and not refilled, the lifespan is shortened.

Gel Cell Batteries

Gel cell batteries are also called Absorbed Glass Mat (AGM). They are typically contained in a black or grey housing. This is to differentiate it from the conventional type. And if it is well set, the battery can be installed on the side or angle of an ATV. Like the conventional type, they also have a filler cap but they are fixed permanently. This is done to avoid spillage of distilled water. It doesn’t require acid to start the engine. This is technologically made possible by an electrolyte that comes already measured to fit the container.

This type of battery is also made up of a fiberglass pad. And Inside the battery, a fiberglass pad is installed between the positive and negative of the plates. These fiberglass pads absorb electrolyte acid inside the battery, therefore, reducing the time wasted on a refill. And that’s why Gel cell batteries are sometimes called maintenance-free batteries because they require less of your attention. But this doesn’t imply that you will never have to check on the battery. From time to time you have to check on the battery so that you can efficiently maintain the good performance of your ATV.

Unlike conventional batteries, AGM batteries are designed with shock and vibration-proof materials. These features make them ideal for your off-road use. So you can take your ATV for a ride in an unfriendly environment without ever worrying about the battery shutting down. On the other hand, Casual use doesn’t dry out this type of battery because they are not vented. So you don’t have to worry about gas emissions because the smoke is contained inside. These AGM battery features have a good track record which makes them cost at a price higher than the conventional type.

Four (4) most important questions to ask when making an ATV battery purchase decision.

For a fact that there are a variety of ATV batteries in stores, you need to make a shortlist of the batteries that actually fit your ATV. The specifications of the quad you own and the physical dimensions of the ATV batteries must tally. And if you already know the physical dimensions of both you can manually set the battery with an ATV. But if you are just replacing the battery then checking the old model would also help find the battery that perfectly fits. Your battery dealer can also assist with the service manual of batteries available for your kind of quad.

Some people prefer battery online shopping. Now, this is only advisable if you already know the model and type of the battery. This will make it easier for you to find a suitable, durable, and reliable battery.

What is the Capacity of an ATV battery?

Knowing the capacity of your ATV is very important. This is critical because you must know how many amperes per hour of electricity that your quad can consume. This can be measured by determining how many amps per hour of electricity is used considering the time it’s fully charged to the time it’s fully discharged.

How is the Cold-Cranking Amps (CCA) for the ATV battery?

Technically, CCA is there to measure the number of amps a battery with a 12V rating can produce at 0 degrees. So the capability of your battery to start an ATV in these low temperatures lies in the higher number of CCA. CCA for any ATV battery should be higher so that cold weather can easily be handled. This feature must be considered if you are a quad owner and you are located in areas that have low temperatures like Europe.

The lower the temperature, the higher the CCA should be must you desire to maintain efficient performance. The performance of any ATV changes in changing weather, and it’s very difficult to maintain the performance of an ATV in places with lower temperatures. And that’s why The Ah ratings and the CCA are some of the most important features to look for when identifying the best ATV battery.

What is the Voltage Rating of an ATV battery?

12 volts is the standard voltage rating for most ATVs on the market. And when fully charged, some ATVs show volts slightly higher than the standard 12 volts. But some batteries require as low as 6V depending on the make and size of an ATV. And others go even as high as 24V. Anything lower or higher than that will not be able to charge an ATV.

On the other hand, the output numbers shown on an ATV are determined by the extent to which the battery is charged. The multimeter is a device that you can use to measure the output numbers.

5. FAQs

Which one is a lot desirable to shop for my ATV, the conventional or AGM Battery?

The conventional batteries, are the foremost cheaper ATV batteries found on the market. Any quad rider with a good but limited budget will have to consider the lead-acid battery as their priority because they are priced a bit lower than the Gel cell type.

The major challenges faced with these forms of ATV batteries are compelled with maintenance. They have to be checked from time to time to maintain good performance. Lead-Acid batteries also come packed with the fill lines that indicate the amount of acid within the battery. From time to time, you will be required to be checking the amount of distilled water in the plates. If the distilled water falls below the line and is not attended to, it will affect the lifetime of the ATV battery unit.

On the other hand, an AGM battery is designed a lot more advanced than a conventional one. Like every innovative company, battery makers tend to improve on the already existing battery brands. And Gel Cell Batteries were created to deal with the failures of conventional batteries. These shortcomings for the most part have to be compelled with the maintenance of the conventional battery. The AGM batteries were designed to avoid the danger of spilling acid and water.

Another advantage Associated with the AGM battery is that of the longer lifetime. They tend to discharge at a slower rate than conventional batteries. This has been made possible by the installation of the absorbent glass layer between the plates. This is again on the AGM battery part. This feature has attracted a lot of quad owners because it does not require an excessive amount of time concerning the maintenance of the battery. In addition to that, those that use AGM batteries have easy access to charge accessories, like heated ATV Grips.

When it comes to battery rating, AGM batteries a little priced than conventional batteries. So if your budget is tight and still want to acquire an ATV battery, then an AGM is not an option. On the positive side, there’s a lot more to achieve from this type of battery. This particularly has to do with the low maintenance needed and acid spillage-resistance. These features have been created in excellence for ATVs. Just like the spoken communication goes “Cheap is expensive”.

What’s the value of an ATV Battery?

Basically there are 3 value ranges within which you’ll realize ATV batteries on completely different markets.

You will realize that some ATV batteries are valued below $50. Once you search at the value tag of these ATV batteries, more options will be tallied with the ATV battery you are requesting. And in most cases, it’s the conventional ones that are available on the market because of the features that make them cheaper. This phase is for the budget tight riders.

You will also realize that there are forms of ATV batteries within the mid-range. These ATV batteries vary from $50-$100. It’s straightforward to seek out a battery that may satisfy your budget and performance necessities in the stated price range.

Finally, we have the premium phase for ATV batteries. These batteries are priced over $100 on the market. And in most cases, these are high-quality batteries that last longer.

What’s the lifetime of my ATV Battery?

There are quite a number of things to think about when deciding on an ATV battery purchase. Long-lasting is always a quality every quad rider looks for in a battery. TV batteries with high-quality have a minimum of three-years and most of 5 years of life. This estimation commences on the day of manufacture from the plant to the end users by the quad user. The lifetime of a battery depends on a couple of factors including:

How a battery is employed

The more you use a battery, the shorter its lifetime. However, there are certain measures you will have to take to make sure that your battery doesn’t get depleted too quickly though. An example is where you will invest in a trickle charger for times when your battery is not in use. The trickle charger will guarantee your battery doesn’t get discharged absolutely from long periods of dormancy.

The counseled Temperature to store the batter

These batteries are escorted with manuals of instruction. An example is where a battery is meant to be kept in a cool or dry place if not use. They also indicate what temperature they are supposed to be kept in and therefore the counseled battery storage temperature is between 32°F and 80°F. And they should be kept away from wet environments. If they’re not properly kept in step with the directions then the period of a lifetime for the ATV battery will be reduced.

The Quality of the Charger

The quad user is not advised to be exploiting the charger that has been counseled by the manufacturer. They are also not advised to be using a charger with the voltage that has not been counseled by the manufacturer. Otherwise, these two factors will lead to a short period of life period for the battery.

Why Isn’t My ATV Battery operating properly?

ATV batteries are scientific inventions and when being handled they should be handle like one. Scientific rules should be followed if the ATV batteries ought to work properly. The most common issues in relation to the ATV battery not operating properly are listed below.

i. Low Fluid Levels

This problem usually occurs in ancient conventional batteries. Therefore if the fluid levels are low battery, then you will want to ensure that the fluid levels leveled up for effective performance.

ii. When the Charging System isn’t functioning well

Basically, there are two unit functions of the engine in an ATV once it’s in motion. The first one is powering the ATV engine. And causing a number of charges to the battery for recharge is the second one. The stator coil is an element within the ATV that is used to recharge the ATV internally. And once this element is wonky the battery won’t be functioning properly.

When do I figure out the time to change My ATV Battery?

In the article, we’ve pointed out what causes the ATV batteries to underperform. Reasons like low fluid (distilled water) and a dysfunctional charging system cause underperformance. In these cases, when things seemingly start to be unhealthy, that’s the best time to get a brand new battery.

Again when you start noticing that the lights on your ATV begin going dim. Or that the ATV won’t start frequently? Then it will be a noticeable sign that the battery is depleting. But before you proceed to buy a new battery, you have to verify that it’s the battery that has an issue. You will have to check if there’s a crack on the battery casing or broken terminals. If there is then it’s the battery that has a problem.

The device used to measure the voltage of an ATV battery is termed the multimeter. Therefore, the surest thing to grasp the lasting of your battery is by checking its voltage output employing a multimeter. And the following is how the multimeter works;

You first have to want to initiate the process by putting the multimeter in place. You have to ensure that you are on the Direct current (DC) setting if you’re employing a meter that doesn’t use auto-ranging.
Since the quality volts for an ATV battery is 12V. And your measurement you see a multimeter reading is beneath 12 V?. If the meter still reads beneath 12V, then it’s likely that your battery is broken or drained and needs to be replaced.


If you are looking for a cheaper ATV battery that can still perform the work, then I recommend a conventional battery. Manufacturers usually offer a 1-year warranty on these batteries. But you have to be ready to refill the batteries with fluids every time they run out. On the other hand, the Gel cell battery comes at a price higher than the AGM because of the technological features it has. These features like permanently fixed filler make it a maintenance-free ATV battery. Protection Status
