Battery Buying Info for ATVs

Nothing can kill your day faster than a dead battery, especially one in your ATV. Whether your old one has gone belly-up or you just need an extra, consider a few things before choosing your next juice box.


When looking for the best ATV battery, you may be tempted just to type in your model name and go with the top result that pops up. Well, that could be a huge mistake as vendors have been known to have the occasional typo in their listings. Many batteries will work in four wheelers that won’t be officially listed as well. It comes down to the battery box or rack on some older ATVs as they tend to be more forgiving when it comes to size.

For our purposes, we chose to go with the manufacturer’s size. Every battery will have measurements, and while you may want to double check a retailer’s specifications against the manufacturers, it is the best way to go. Alternatively, you can check your owner’s manual or online literature for your model of off-roader to find a compatible battery number or an OEM juice box in some cases.

Battery Type

If you have owned a motorcycle or ATV in the past 20 years, you have probably used an SLA or AGM battery. Those are by far the two most common styles today, and they are made to be safe when it comes to acid or any other harmful chemicals. They each have their own advantages and disadvantages as does the new breed of Lithium-Iron ATV batteries.

  • SLA – This stands for Sealed Lead Acid, and was by far the most common type of battery around for years. These are either SLA or VRLA, which means Valve Regulated Lead Acid and are built to be safe, maintenance free batteries.
  • AGM – An AGM battery is also an SLA battery as it is sealed, but works in a different fashion. It has an “absorbent glass matt” which absorbs electrolytes and acts like a sponge. These are optimal for ATVs as they can be mounted in some crazy positions that a regular SLA battery cannot.
  • Lithium Iron – These are still relatively new on the scene and for use Lithium-Iron Phosphate to kick start your bike. These are more stable than Lithium-Ion batteries, which means they are safer and less prone to thermal overrun. They are also extremely light compared to traditional batteries.


While all our batteries work well in ATV’s, some consumers don’t use their four wheelers all year round. That means you may want to pop the battery out and use it in something else if you are a true weekend warrior. If that’s you, you may want to think about storage of the battery when it is not in use along with any other wheeled vehicles you may want to power over the course of four seasons.

Top 5 Best ATV Battery Reviews

1. Mighty Max YTX14AH 12V Gel ATV Battery

The world of Powersports is vast, and if you own a vehicle that fits the bill, you have probably owned a battery from Mighty Max. Our top choice for the best ATV battery is their YTX14AH, which is a 12V Gel-based battery that is capable of producing 220 cold cranking amps. As it uses Gel, there is no acid pack, and it will be maintenance free which is great when you want to think about riding, not topping off a battery.

The nature of this particular battery allows it to be mounted in a variety of positions although you still have to keep the size in mind along with the terminal area. Negative is on the right, and Positive is on the left on this big battery which measures 5.27” long x 3.5” deep and 6.53” tall. It comes with screws, but you will have to provide your own hardware as is usually the case.

The Mighty Max YTX14AH weighs in at a little over 10 pounds which is about the average for this class. It’s an excellent deep cycle battery that will fire up you four wheeler with ease and is built to last long after others falter. If you care about looks, it is by far the best-looking battery on our list as well.

2. YUASA YTX14-BS Maintenance Free Battery

YUASA’s entry onto our list is another 12 Volt juice box that throws out 200 cold cranking amps whenever they’re needed. It’s not quite the looker of our top choice but will perform just the same sans the Gel-based interior. It’s close to the same size as well measuring 6” x 3.4” x 5.8” although it’s going to be a few pounds lighter at 7.8 lbs.

One perk of the YTX14-BS is the fact the company actually lists some of the four-wheeled wonders it will work with. You’ll quickly find out plenty of manufacturers don’t do that, so newer owners will appreciate the fact there are over 40 models to peruse. We won’t list them all, but some models represented include the Honda FourTrax, the Shadow Spirit, the Suzuki Eiger and their KingQuad. You will still want to take that listing lightly as the measurements are the best way to go.

The YUASA YTX14-BS is another battery for ATV vehicles that is billed as “maintenance free” although there is something you will have to do before using it. It is an AGM battery, but ships to you in a dry state, so you will have to fill it yourself. Once that’s done, you are good to go however as you’ll never need to top it off. It is still a step worth mentioned however considering you can buy a battery ready to go.

3. Mighty Max Battery for Polaris 500 Sportsman HO

This ATV battery from Mighty Max is for the Polaris 500 Sporstman HO ATVs which were manufactured between 1996 and 2013. That covers a lot of four wheelers, and this 12V battery can start any of them with 210 cold cranking amps of power.

This is a sealed lead acid battery with AGM tech built in to keep you (and your ATV) safe from any potential spills. This also allows you to install it at odd angles although you shouldn’t have to if you strictly stick with Polaris considering that’s what it was built for. The battery is tall measuring 5” x 3.5” x 6.5” with the negative on the right and positive on the left.

As mentioned in our buying guide, just because a battery is listed for a particular product doesn’t mean you can’t use it in another. While the YTX14AH is geared towards the Polaris, it will work with other ATVs if the size is right. The battery weighs 10.14 pounds and comes with a 1-year warranty which seems low, but is usually the standard.

4. Expert Power 12V 3AH Sealed ATV Battery

Need a battery that can work in your ATV, scooter or anything else requiring 12 volts of power? Well, you will certainly want to consider this one from ExpertPower as it works with a wide range of vehicles. It is also one of the more compact models to make the grade measuring 4.4” x 2.75” x 3.3”.

We aren’t going to go through the full array or ATVs and bikes this one will work with, but it is a replacement for the YTX4L-BS, YT4L-BS, GTX4L-BS, and WPX4L-BS. That covers many leading ATV brands along with some scooters and motorcycles as well, and it’s the perfect size for lawn tractors and other equipment needing a small 12V battery.

Due to its size, we feel this is the best multipurpose battery you can buy, and it can cover anything from a Suzuki 350 from the mid-90s to the 2006 Bombardier ATVs. It is very light as well at around 3 pounds. It may not be stylish, but it packs a punch despite its small form factor.

5. ThrottleX Batteries ADX14-BS Sport Battery

Rounding out our Top 5 is another tall 12V battery built for Power Sports vehicles like ATVs. This AGM battery uses advanced Lead Calcium tech that helps combat sulfation and produces increased starting power. The spill-proof battery is maintenance free and ready to roll to go out of the box, so you will be on the trail in no time.

As mentioned, the ThrottleX ADX14-BS is taller than it is long, measuring 5.8” x 3.8” x 6.9”. That’s around the same size as the ones from Mighty Max and others, so you will be good to go with brands like Polaris, Grizzly, Arctic Cat and others. You will want to make sure your terminals line up if you’re going to try something off book however so keep in mind that the negative is on the right and the positive will be on the left.  Overall, it’s of average size and won’t let you down in a pinch as it performs admirably.

If you need a reliable replacement battery for your ATV, the ADX14-BS Power Sports Battery is an option worth considering as long as you can get by with 220 cold cranking amps. Most folks can, and the fact it is an AGM battery is the icing on the cake if you prefer that style over Gel-based or old-school SLA’s.
