Your ATV is more than just a way to cut loose on the weekend; it’s your baby. It’s how you connect with friends and family. It’s a way to get out in nature and way from the rest of the world.
This is why it’s important to use the best parts in your ATV.
You need a battery with the durability to stand up to hours of riding tough trails. And you need enough cold cranking amps to get started in any conditions.

The 8 Best ATV Batteries 2021 Reviewed
1 MMG YTZ14S Z14S Lithium Ion Sealed Powersports Battery
The MMG YTZ14S is a compact battery for applications where space is an issue. It measures 3.4”x5.9”x3.7”, and weighs only 4.14 pounds. That makes it the lightest battery we reviewed, and one of the smallest. It will fit in virtually any motorcycle, ATV or jet ski. Just make sure and check the manufacturer’s website to make sure it will work for yours. If it’s too small for your battery compartment, it may rattle around and cause damage.
The red plastic case is solidly built, and the battery contacts are compatible with marine applications. There’s a convenient test button on the top that lets you check the current voltage without any extra accessories. Just press the button and the current voltage will read out on a digital display.
It’s a Lithium Ion battery, which means you won’t have to worry about refilling power cells. You also won’t have to worry about burning yourself with corrosive acid. This can be a concern with lead-acid batteries, which need to be refilled periodically. Unfortunately, this battery does not perform as well in the cold as many others. This is due to its small size and lack of redundant power cells.
The MMG YTZ14S can be charged on most aftermarket chargers. You can also put it on a trickle charger to maintain voltage over the winter. It will work on any charger that provides between 2.5 and 20 amps. It also comes with a 6 month replacement warranty, so you can buy it with confidence. The price is higher than some comparable batteries, but it’s well worth it considering the small package.
2 Yuasa YTZ10S Factory Activated Maintenance Free Battery
This is a great choice when finding the best ATV battery. The Yuasa YTZ10S is a 7.05 pound, 5.9”x3.4”x3.7” battery. It fits in the same compact category as the MMG YTZ14S, though it’s a bit heavier. This battery has been the OEM battery for a variety of Honda motorcycles for more than a decade. It will also fit in many other vehicles. Just check with your manufacturer first to make sure it’s compatible.
The case is made of solid black plastic. The top is slightly softer, which is nice when you bang a knuckle on it in tight quarters. The contacts have restraining brackets for the nuts, which is a nice feature. You can hold a flashlight in your free hand, instead of using it to catch the nut. If you’re working on your ATV in the woods, you won’t lose your nuts in the leaves.
The Yuasa YTZ10S is an electrolyte filled battery. Like a Lithium ion battery, this battery will never need to be refilled. This is a huge plus, particularly if you find yourself needing to do maintenance in the field. You also won’t have to deal with any acid. This battery delivers strong cold crank amps, and is powerful enough to get your ATV running well below freezing.
This battery will charge on most aftermarket chargers. It will also work with a trickle charger. This ties well with its good cold crank amperage to make it a decent cold weather battery. It’s a little small for snowmobile use, but it’s perfect for any weather you’ll be running an ATV in. It has a one year manufacturer’s warranty. In terms of price, it’s higher than some other choices, but that’s to be expected in a compact battery.
3 ExpertPower PowerSport Maintenance Free Battery
The ExpertPower PowerSport is the first mid sized battery on our list. At 5.9”x5.1”x3.4”, it’s beefier than the previous two batteries. It’s not much heavier, though. It only weighs 9 pounds. This battery is designed for heavier duty power sports vehicles. It meets manufacturer specs for a variety of heavy cruisers, so it will have no problem pushing enough volts for your ATV. It’s the recommended replacement for most Recon ATVs. It’s also the OEM replacement for some heavier Honda bikes.
The case is a little more flimsy than the previous two batteries. The top also doesn’t mount 100 percent securely. This makes us a little nervous about the PowerSport’s durability on the trail. In terms of other features, this is a bare bones battery. The price reflects that, so it won’t break the bank. This is a budget battery that does what it advertises, and no more.
The PowerSport is a lead acid battery. While ExpertPower claims that it’s maintenance free, we have yet to see a lead acid battery that doesn’t need some TLC from time to time. This means that over time, it may need to be refilled. If you need to do this, do some research first. It’s safe when done properly, but there are strong acids involved. Invest in some rubber gloves and chemical splash goggles at a bare minimum before you do this.
To delay having to refill the cells, keep your battery well charged at all times. A trickle charger can help with this. Keep your battery on the charger during extended periods of inactivity, particularly over the winter. The ExpertPower PowerSport comes with a one year manufacturer’s warranty.
4 Odyssey PC545 Powersports Battery
The Odyssey PC545 is the smallest battery we reviewed, at 3.1”x1.7”x2.7”. It’s also the heaviest, at 11.4 pounds. All that weight comes from the pure lead plates that replace granulated lead in the construction. With this technology, Odyssey is able to deliver 12 volts from a package that’s smaller than most cell phones. This is a premium, purpose-built power sports battery. It’s nobody’s OEM, but it’s everybody’s dream. Check your manufacturer’s guidelines to see if it’s compatible with your ATV.
One thing that impressed us about the PC545 was the tough, durable place case. It’s made from rubberized plastic that can really take a beating. This battery will stand up well to use on even the most rugged trails. Another awesome feature of this battery is the contact nuts. They’re large, they’re plastic, and they’re easy to grip. Kudos to Odyssey for saving us from messing around with a wrench.
This battery has a sealed design, and will never need to be refilled. Because the lead plates are packed tightly inside, it’s also impossible to spill without taking a chainsaw to it. Because of this design, the PC545 can be mounted in any configuration. Right-side up, upside down or on its side, this battery is good for a variety of mounts.
This battery has smaller, recessed charging posts. Any charger that uses alligator clips should work fine. For other charger types, it’s best to check first. Odyssey advertises a 7-10 year life. That said, it’s sure to last longer if you keep it on a trickle charger over the winter. The PC545 comes with a two year manufacturer’s warranty.
5 CB Chrome Battery YTX30L-BS
The CB YTX30L-BS is a larger battery, measuring 6.89”x6.64”x4.96”. At 10.73 pounds, it’s also fairly heavy. It’s the recommended OEM replacement for several Harley-Davidson cruisers, and a variety of Polaris power sports toys. It also fits in a variety of ATVs, dirt bikes and jet skis. Check your manufacturer’s guidelines to make sure it’s compatible with your vehicle.
This is another durable, trail-hardened battery. The case is made of tough, durable plastic that feels like it can stand up to a sledge hammer. The top of the battery has a non-conductive aluminum guard that rests just over the terminals. You can literally drop the YTX30L-BS off your roof and it will still work. This battery comes from the factory fully charged, so you can hook it up right away.
Like the Odyssey PC545, the CB YTX30L-BS will never need to be refilled. It has a cutting edge, Absorbed Glass Mat design that makes it not only long-lasting, but spill-proof. This battery can be mounted in any configuration. The posts are also sealed to reduce corrosion. This improves the life cycle of the battery. It also delivers a truly insane 360 cold cranking amps. This isn’t just a great ATV battery. It will also start your snowmobile in -30 degree weather.
This battery is compatible with most aftermarket chargers. Larger alligator clips can be harder to maneuver around the post guards. It works just fine with most trickle chargers. It also comes with an 18-month manufacturer’s warranty.
6 CB Chrome Battery YTX14-BS
This is a smaller, lower priced version of the CB YTX30L-BS. It measures 5.71”x5.8”x3.26”, and weighs 9.7 pounds. The CB YTX14-BS is the recommended OEM replacement for many mid-sized Harley-Davidson cruisers. It’s also standard on several Yamaha bikes. That said, it’s a great option for ATV owners. As always, check your manufacturer’s guidelines to make sure this is the right battery for you.
This battery is as well manufactured as its older brother. The shell is tough, and the top has a similar protective aluminum shield. This battery also arrives fully charged. No need to add water or put it on a trickle charger. Just hook it up, and your ATV will be ready to roll. This battery will stand up to even the most rigorous trail use.
The CB YTX14-BS will also never need to be refilled. It’s an Absorbed Glass Mat battery, which means that not only is it maintenance-free, it’s also spill-proof. This battery can be mounted upright or on its side. It doesn’t matter. It will run for years without spilling acid on your motor. It does fall short of the YTX30L-BS in one category: cold crank amps. It only delivers 200, which is good enough for fall riding, but we’d prefer more in winter.
It will work well with most aftermarket chargers. As before, the post guard may interfere with some smaller alligator clips. The CB YTX14-BS comes with an 18-year manufacturer’s warranty.
7 ThrottleX Batteries – ADX9-BS – AGM Replacement Power Sport Battery
The ThrottleX ADX9-BS is another mid-sized battery, measuring 6”x3.43”x4.19”. It weighs only 8 pounds, making it the lightest mid-sized battery we looked at. This battery is the recommended OEM replacement for several Polaris ATVs. It’s a good battery for many ATVs, snowmobiles and jet skis. Check with your manufacturer for compatibility if this isn’t your OEM replacement battery.
The case is made of a rubberized plastic. It isn’t as heavy as the more durable cases we’ve reviewed, but it’s good enough for trail use. The top is extra soft, and extends above the contact posts. We appreciated this feature, since it made the ADX9-BS relatively drop-proof.
Since this battery uses Absorbed Glass Mat technology, it will never need to be refilled. It’s also spill-proof, and can be mounted in any configuration. Where this battery falls short is cold crank amperage. It only delivers 120 cold crank amps, so it may be a poor choice if you live somewhere where winters get cold.
The ADX9-BS will work well with almost any aftermarket charger. The posts are multi-directional, so you can hook in either from the front or the sides. If you’re buying this battery, you’re probably using it in winter. Make sure you take advantage of how easy it is to hook up a trickle charger. The ADX9-BS comes with a 30-day money back guarantee, and a one year replacement warranty.
8 Mighty Max YTX14AH
The Mighty Max YTX14AH is our final entry, and it’s a medium sized battery. It measures 5”x3.5”x6.5”, and weighs a moderate 10.14 pounds. This is purely a replacement battery. It’s not anyone’s OEM. It’s a solid, all-around power sports battery, useful for motorcycles, ATVs and jet skis. Your manufacturer will know whether this battery fits your ATV.
Like the ADX9-BS, the YTX14AH has a rubberized plastic case. This makes it extremely durable, and allows it to stand up to years of abuse. It also has an extra soft top, which stands higher than the contact posts. This makes the YTX14AH virtually drop-proof.
This battery uses Absorbed Glass Mat technology. This means it will never have to be refilled. It’s also spill-proof, which means you can mount it in any direction. Whether your ATV is designed for an upright battery or a side-mounted battery, the YTX14AH will get the job done. That said, it only delivers 210 cold crank amps. If you live in a colder climate, you’ll want to take that into consideration.
This battery works well with most aftermarket chargers. Like the ADX9-BS, it has multi-directional posts. You can connect this battery from the front or your side, on your charger or on your ATV. This charger also comes with a 30-day refund policy, as well as a one year manufacturer’s warranty.
Best ATV Batteries Buying Guide
The kind of battery you buy is going to depend on many factors. Your ATV, your mount style, your riding style, and even your local weather can play a factor. Before you buy, consider a few things:
- Is it compatible with your ATV? This is easy to overlook, but it’s the first thing you should check when you’re buying an ATV battery. Battery mounts can vary by make, model, model year, and even on different packages of the same model. Batteries can be mounted upright or on their side. Contacts can connect from the left or the right, and positive and negative terminals can be on either side.
- What kind of weather do you ride in? If you’re a warm-weather rider or live in the South, you may not be worried about cold crank amps. On the other hand, if you like to ride when the weather’s crisp, cold crank amps may be everything. Exactly how many cold crank amps you need will depend on what ATV you ride. A 400cc motor will require less amperage to start than a 1500cc motor. This is another thing you’ll need to check with your manufacturer about.
- How much weight is acceptable? For casual riders, the difference between a 7 pound battery and an 11 pound battery is trivial. You won’t notice any difference in terms of everyday performance. That said, you may be a competitive rider. If you’re going for maximum speed, every ounce can mean lost acceleration and lost races. You’ll also be less concerned about durability and cold crank amperage. In that case, a lighter, lower performance battery may fit the bill.
- What kind of battery is it? Lead acid batteries deliver the best overall performance at the lowest cost. This is a time-tested, proven design that’s easy to manufacture. Budget batteries tend to be lead acid, and honestly they should be. If you see a cheap battery that’s of a different type, steer clear. They had to save money somewhere else to afford a more expensive design. On the other hand, lead acid batteries can be time-consuming and dangerous to maintain. If you can afford it, consider another option.
- How durable is the battery? For riding on a road or a track, car-style batteries will do the job just fine. If you’re riding in the woods, on a trail, or over obstacles, consider a more durable battery. Vibrations, jolts and other rough activities can take a toll on batteries, causing them to leak. Trust us, you don’t want to be cleaning up that kind of corrosive mess.
- Cycle life and warranties. Like with anything you buy, look for a good manufacturer’s warranty. This tells you a lot about what they think of their own product. Also, make sure to look at the manufacturer’s rated cycle life for the battery. This tells you how many times the battery can be fully charged and discharged during its lifetime. Batteries with a higher cycle life will tend to last longer.
A good battery is one of the most important purchases you can make for your ATV. If your ignition doesn’t turn over, nothing else matters. A discount battery may look like a good idea at first, but it may fail when you need it most. The last thing you want is to be broken down out on the trail. A better battery may cost more, but it can be well worth the investment.
