Your Complete Guide To The Best ATV Batteries for 2021 and Beyond

Nothing beats the freedom of riding on your ATV, am I right? No roads? No problem! 

Part of the fun of having an ATV is in plowing through whatever is in front of your quad – be it a challenging mountain trail or a bumpy forest path.

It goes without saying that a beast like that needs all the power it can get for optimal performance. That’s where the proper ATV battery comes in. Skimp on this, and you’ll be limiting your ATV’s true potential.

And you definitely don’t want to wait until your battery dies on you before you go out hunting for a new one. Not only will your ATV not run, but you run the risk of potentially damaging it. Now that’s not fun at all!

So that’s why it’s recommended that you get the best high-performance ATV battery that’s a perfect fit for your ride sooner, rather than later. Your quad and future self will thank you for it.

But, how do you go about picking the best one?

Today, the battery guys will take you through everything you need to know to buy the best ATV battery for your sweet ride!

A Quick Guide on Buying the Best ATV Battery

Hunting for an ATV battery can be a daunting task, but it doesn’t have to be. Most of your buying decisions will be influenced by the type of ATV you have, where you use it, how often you ride, and even the weather you’re in.

A little homework and research are therefore necessary. But don’t worry, all that effort will pay off, and you'll be rewarded with a great ATV riding experience each and every time.
So here are some questions you need to consider before buying:

What are your ATV's specs?

It might seem obvious, but you’ve no idea how many people fail this crucial step and end up with a battery that's a horrible fit. So do check your ATV's make, model and year to see which batteries are compatible.

Also, check your ATV battery mount itself. Measure the dimensions of your stock battery (the one included with your ATV) and check where the connection terminals are.

When in doubt, favor a slightly smaller battery. You might be able to get away with that versus an oversized one. Just make sure to wedge it in place with things like thick cardboard. A loose battery rattles around while riding and will lead to damage.

What's the weather like while you're using your ATV?

You might be thinking, how does weather play a part in my battery buying decisions? Well, it has something to do with your battery’s Cold Cranking Amps or CCA rating. CCA tells you how much burst of power the battery can supply to fire up your ATV.

Fun Fact: Wonder why it’s called cold cranking amps? Well, CCA refers to how many amps a 12-volt battery can supply for 30 seconds at a chilling 0 F temperature.

Lower temperatures generally require higher starting power, so CCA becomes an important consideration. So if you plan to do a lot of winter riding, you might need a more powerful ATV battery.

On the other hand, people living in warmer climates might just need the bare minimum CCA rating, or if you choose not to ride out during the winter months.

How often do you plan on using your ATV?

Unlike motorcycle batteries or car batteries, ATV batteries are used less often. Unless you come to work everyday riding a quad (if you do ride to work on an ATV, send us a video! We'd love to see that!)

So considerations for an ATV battery are different. If you plan on using it only occasionally, then you need a battery that can last longer between recharge cycles. Batteries that can’t do this risk emptying out, and you’ll be left with an ATV that won’t start.

If you don't plan on using your quad during the winter months, you also need to get a battery that can hold a charge long enough to survive that time. By the way, this is a great workaround if you’d rather not invest in a high CCA rated ATV battery.

How much power does your ATV need?

Many different ATVs need varying amounts of starting power, so know your model’s CCA needs.
The battery should meet your ATV’s CCA requirement at the minimum, but we recommend exceeding it as much as your budget will allow.

This is because as batteries age, their starting power starts to decline. An ATV battery with a higher CCA rating can compensate for this, so you can use it for far longer.

In addition, having extra accessories can add up to your CCA requirement. I mean, getting extra bright lights or a radio looks cool and all, but consider the drain they’re making on your battery.

If you plan on pimping out your ATV with all the bells and whistles, consider a stronger battery, you need an ATV battery with higher CCA and amp ratings. And if you plan to take your pimped out ATV out in the winter, then buy an even more powerful battery.

Where do you ride your ATV?

ATVs are built for off-road driving, but how rugged of a ride are you looking at? If you’re an aspiring daredevil or even have the slightest plan of doing lots of rough road riding in the future, go with a heavy-duty battery.

A cheaper and less durable battery might not survive such punishment, and you’ll end up with battery leaks that you’d not rather handle on the road.

What type of ATV battery is best for your needs?

Different kinds of ATV batteries have their own pros, cons and price points. Knowing the basics of each can better inform you on which one to pick.

Batteries generally come in two forms – lead acids and lithiums. Lead acids are the “traditional” batteries. Thanks to decades of experience developing and making them, they’re generally durable, reliable, economical and overall great at their jobs. For most owners, lead acid ATV batteries are a solid choice.

Lithium batteries are the newer kids on the block – they charge faster, have more capacity, weigh lighter and are generally longer lasting. They’re also more expensive. If you have lots of dough to spare, they’re a good investment.

Within the lead acid ATV battery family, there are more choices that we feel you deserve to know. The conventional lead acids require a constant topping up of water and has the risk of leaks, so we don’t really recommend them that much.

Instead, go for maintenance free ones. These are in the form of either gels or absorbed glass mat (AGM) batteries. AGMS have more starting power over gels, but the latter discharges more slowly. But in practice, you can’t go wrong with either.

How long do you want your ATV battery to last?

You might be thinking, “is this a trick question?” – of course the answer is “as long as possible”!

Unfortunately, ATV batteries don’t last forever, so you need to be realistic about it. How long your batteries last depend on the very factors we’ve discussed above. On average, most batteries should have a useful life of anywhere from 3-6 years.

Warranties are another thing to consider. They’re your insurance policy should anything go wrong. And trust us, even the best batteries from the best brands suffer from this once in a while.

Most reputable battery manufacturers offer a 12-month warranty, so that’s a good benchmark when you’re out comparing warranties.

So sit back, relax and let’s go on to it!

Best value for money ATV battery is the Expert Power ETX9-BS


Expert Power ETX9-BS

Check LATEST Price

One of the best value ATV batteries you can buy, the Expert Power ETX9-BS is an excellent combination of affordability and performance.

Don’t let its small size fool you – this is a powerful, hardworking piece of electrical equipment. In fact, it uses its compactness as an advantage, as you can fit this battery in a host of other equipment – from solar panels, generators, and motorcycles.

As an ATV battery, this one covers all of the basics. We hooked it up as a replacement battery for our aging Honda 300EX, and it fired up as if it was brand new, with a constant voltage exceeding the 12-volt minimum. Note that we’ve replaced it countless of times with stock batteries over the years, and it lasted us a few years at best. We reckon the ETX9-BS will best that record!

Self-discharge rate during periods of non-use is impressive at only a 3% loss. Expect your ATV to start right up even when left unused during the cold winter months or for very long periods, for example.

Construction is definitely durable, and AGM technology ensures there would be no hazardous leaks, even when the battery itself is damaged.

The only minor drawback is the “just enough” CCA rating of 105. Well, it’s a drawback depending on where you live and how overpowered your ATV is. Colder temperatures or lots of extra add-ons might give this one a hard time, but folks living in warmer weather need not worry about it too much.

Also, a thing to note is that since it’s compact, it can be a bit smaller than some stock batteries. If this is the case for you, simply wedge in some fillers for a snug fit. At its worst, it’s just a very minor inconvenience.

Overall, the ETX9-BS is an excellent pick if you want a basic ATV battery that performs exceedingly well. With a price that is hard to beat in its class, it’s a great return on your money.

The best premium ATV battery is the Odyssey PC545


Odyssey PC545

If it were possible to climb Mount Everest using an ATV and you had the Odyssey PC545 ATV battery, you'll be glad to have it on your side.

The PC545 is undoubtedly playing at the big leagues. Right off the bat, we noticed the rugged and durable outer case that makes the Odyssey effectively shock and vibration proof. The mounting and terminal plates are also made of 100% pure lead and feature excellent workmanship.

In short, this thing is built to withstand some severe punishment that will crumble other lesser batteries. If you plan on regularly taking your ATV through some challenging terrain, then the PC545 is an absolute requirement. We won’t be surprised if this battery outlasts even your ATV!

Performance wise, the Odyssey is a beast, boasting 150 CCAs that will satisfy even the most power hungry ATVs. It also charges blazingly fast – 100% in around 4 hours to be exact. That’s faster than any battery we’ve tested thus far (save for the pricier lithium ions)

The PC545 is genuinely made to be the last battery you'll ever need. Odyssey promises an impressive service life of around 3-10 years. They’re so confident, in fact, that they offer a full 2-year replacement warranty. Now that’s backing up your claim!

For all its power and longevity, by now you’ve probably guessed its most significant drawback – price. This will really set you back a bit, but in our opinion, the return you'll get is more than worth it.

All in all, this is a good purchase if you're a rough riding ATV owner looking for a heavy-duty, top of the line ATV battery. The Odyssey PC545 is the kind of ATV battery that you’ll depend on for years to come.

The best budget ATV battery is the Upstart Battery UB-YTX12-BS


Upstart Battery UB-YTX12-BS

Check LATEST Price

In terms of having a bargain price combined with decent performance, few can beat the Upstart Battery UB-YTX12-BS.

At its core, the UB-YTX12-BS is a simple ATV battery that covers all the minimum requirements. Given its low price point, we’re pleasantly surprised it uses maintenance-free gel technology that fulfills the needed 12V and 10 Ah for most ATV applications. No need to mess around with topping up or anything, which is convenient.

Its most significant advantage is most definitely its price. This is a very affordable ATV battery, probably one of the lowest priced you’ll ever find. It even beats out our local WalMart the last time we checked. We won’t be surprised if folks stocked up on these – they make great backup batteries.

This alone makes the UB-YTX12-BS worth trying out. The potential reward of getting a battery that works while saving lots of $$$ down the road is hard to pass up. And they’re even throwing in a 12-month warranty to sweeten the deal.

With that, though, you do get what you pay for. While the overall construction is durable enough to withstand some wear and tear, the packaging, unfortunately, is not. It's very flimsy and thin, which has the potential to damage the battery if your shipper is not careful enough. Ours luckily came through intact, but some people we've talked to aren't so fortunate. 

Still, being very inexpensive, it’s still well worth the risk. You get a hardy and performance ready ATV battery at rock bottom prices with a 12-month warranty for added insurance. For the cost conscious ATV owner who wants a no frills battery, the UB-YTX12-BS might be the perfect match.

Yuasa YTZ10S

For the enthusiast who owns an ATV beast with all the add-ons, you need all the extra raw power you ATV battery can muster. Enter the Yuasa YTZ10S

ATV and motorcycle owners would probably recognize Yuasa. They’re one of the most trusted names in automobile batteries, so you’d know their reputation backs up their products pretty well. The YTZ10S is no exception.

This battery churns out a massive burst of 190 CCA. This is way, way more than enough to power the ATV itself, plus any aftermarket accessories it happens to have installed. The high CCA also ensures you reliably start your ATV even in the coldest of weather (snow driving, anyone?)

Ever wanted to reap the benefits of a lithium battery but have been put off by the high price tag? The MMG YTZ14S Lithium Battery is here to finally change your mind.

Take the YTZ14S out of the box, and you’ll notice one thing right away – how freaking light it is! Really, it feels like a hollow case instead of a full-fledged ATV battery. But trust us – it’s the real deal. This battery weighs 1/3 less than comparable lead acids. This alone sheds a lot of pounds off your ATV and can lead to speed and performance gains.

Performance wise, the MMG is leagues away from what lead acid batteries are capable of. This battery boasts a cycle life that is easily 10 times longer, and it charges incredibly fast. This ultimately means this battery is designed to last for years.

The 290 CCA it provides is no joke either. This is perfect for starting up a fully decked out ATV in sub-zero temperatures (if ever you find yourself in that situation!)

Our top choice for the best ATV battery is the ThrottleX ADX14AH-BS


ThrottleX ADX14AH-BS

Check LATEST Price

Our personal pick for the best ATV battery comes in the form of the ThrottleX ADX14AH-BS. This AGM battery aims not just to meet your battery needs, but to exceed them. But can it really?

First off, we checked the CCA rating. At 220 CCA and 12 Ah, this is certainly more than enough to start up your ATV. You’ll have so much excess power, in fact, that you can power up your quad in sub-zero temperatures or load it up with all the accessories you can think of.

This battery is highly resistant of the #1 battery killer – sulfation. This build up occurs over time in all lead acid batteries and can lead to loss of starting power and reduced battery life. The ADX14AH-BS delays this thanks to the advanced lead-calcium technology used in this ATV battery. Having a high CCA rating leads to better life and performance as well.

Installation went smoothly without a hitch for us. Battery fit snugly in our Polaris Trailboss 330. Your mileage may vary, though. Some people have reported having slight difficulty fitting the battery in. Best to check your ATV battery’s dimensions just to make sure. We personally didn’t use the included nuts and bolts, but it’s a nice bonus and might be useful for some folks.

Longevity wise, we’ve seen people use this for years at a time. On average, you can expect this battery to last for around 3-5 years. Not bad for an ATV battery that costs a little over $50!

And as icing on the cake, it includes a 30-day money back guarantee with a full 12 months warranty. Hard to say no to that!

If you value above average performance and power with a price point that won’t require you to take out a small loan, go for the ThrottleX ADX14AH-BS. Overall, it definitely exceeded our expectations!

Frequently Asked Questions:

Are all ATV batteries the same?

Batteries are one of the most important components of your ATV. And to run them, there are different types of batteries. So no, not all ATV batteries are the same. There are conventional ATV batteries that are also known as wet or flooded battery. Then there are AGM or Absorbed Glass Mat batteries. And finally, there are Gel Cell batteries.

What is the best battery for an ATV?

AGM batteries are considered the best for an ATV. For the best battery, you should look at the manual of your ATV. Since AGM batteries are designed to be shock and vibration proof, they are ideal for off-roading activities. They also require less maintenance and deliver reliable power. So wherever possible, shop for AGM battery of any brand.

How do I choose an ATV battery?

The first thing you need to do is look at your ATV brand and model. Then turn to vehicle manual for specifications on battery size, CCA, and Amp/hr. When you shop for an ATV battery, you should look for similar specifications. Furthermore, it's ideal if you purchase AGM batteries. These offer the overall best value and reliable current to your ATV.

What do ATV battery numbers mean?

You'll see the label that reads something like this "YTX14 A H L-BS-1". The first three letters represent the battery model of YUSA. Different brands will have their model number. The next number "14" is the battery performance classification. A is the unique battery case size. H is the CCA power. L is polarity location, BS is either factory activated/bottle supplied designation. And 1 is the unique terminal style.

Does it matter what kind of battery I put in my ATV?

Yes, it matters a lot in terms of performance. You should ideally get the batteries that are meant for your ATV brand and model. You can choose from three different types, which are AGM, wet or flooded, and gel cell. AGM batteries are considered more reliable and durable. Gel cell is similar to AGM batteries. Wet batteries aren't good for off-roading and they're prone to spillage.

How many cold cranking amps do I need for my ATV?

It depends primarily on your ATV brand and model. But you should go for batteries with higher cold-cranking amps. This way, the battery will be able to start your ATV even in freezing temperatures. There are batteries with a CCA of 675 and above, but batteries with a CCA of 500 are suited for most cases. If you're not living in colder regions, then a CCA of even 250 will do good.

Are Energizer ATV batteries good?

Yes, Energizer is a reputed battery brand that sells batteries for a variety of appliances. It offers the Energizer Premium AMG specifically designed for vehicles. It has an extremely high vibration resistance and cyclic stability. The company claims this model lasts 3x more than standard batteries. Check with the retailer for ATV compatibility before purchasing.

Why does my ATV battery keep dying?

Unlike cars, ATV is used very infrequently. And this is the main reason why ATV batteries die. You should drive your ATV everyday or at least every other day to keep the battery from dying. Leakage and spillage are another reason why batteries wear out. Especially in case of lead-acid and wet batteries, the liquid may leak if there's a crack. Finally, the battery may die as it ages.

How do you start an ATV with a dead battery?

You can try jump-starting your ATV. Connect your vehicle to another powered battery and start your ATV. Or you can try compression start. In this case, you essentially trick your ATV into starting. When you move the wheels, the engine starts rolling over. So as you drive, it can charge your battery.

When should I replace my ATV battery?

You should replace your battery a few months before the battery lifecycle. If the battery is designed to run for 3 years, then you should ideally get it replaced within 2.5 years. This depends on how frequently you're driving your ATV and your maintenance habits. As and when you replace your ATV battery, get a similar battery that matches your ATV model.
