1. ThrottleX ADX15

The ADX15 does everything right and at an affordable price. With an impressive 220 CCA and 14 Ah, it’s one of the best batteries for the Polaris Sportsman 500 when it comes to reserve power.

Not only that, but it’s completely spillproof thanks to its Absorbed Glass Mat (AGM) design and is designed to withstand the rigors of off-roading. Unlike conventional Lead Acid batteries, the ADX15 is much more resistant to vibration and shock.

The ADX15 is our favorite battery for the Polaris Sportsman 500, because it has a very impressive 220 Cold Cranking Amps for reliable cold starts and a whopping 14 Amp Hours. This means that the ADX15 can supply 1 Amp for 14 hours straight, which makes it the perfect choice if you’ve got more electrical accessories installed, like heated grips, seats, or a winch.

All of that at such a price point is quite impressive.

2. Pirate Battery ‎14A-A2

Another great choice is the Pirate Battery ‎14A-A2, which provides an impressive 210 CCA and 12 Ah, and costs quite a bit less than the ADX15 above.

This battery is designed especially for use in off-road vehicles and can handle the vibrations, bumps, and jolts that come with taking your Polaris Sportsman 500 off the beaten path.

The Pirate Battery ‎14A-A2 is a much less expensive alternative to the ThrottleX ADX15 above, and it carries only a few Cold Cranking Amps and Amp Hours less than the ADX15 above.

Now, one thing that we did not like about this battery is that it didn’t come with the bolts/nuts included and the battery posts were quite flimsy. However, if you don’t overtighten the posts too much, they should not bend. These are the few compromises that the manufacturer (Chrome Battery) had to make in order to bring the price down.

All in all, it’s a very powerful battery and very affordable too. If you’re on a budget, then the 14A-A2 is the obvious choice.

3. NICHE 519-CAB2228T

The NICHE 519-CAB2228T is a very high-quality battery, with 210 CCA and 12 Ah to power even the most power-hungry accessories on your Sportsman 500.

It’s an AGM design battery, therefore it’s completely maintenance-free and spillproof. This means you’ll never have to worry about topping up battery acid or any spills if your ATV rolls over.

The NICHE 519-CAB2228T is also available with a smart charger as an optional extra if you don’t have one, but you might be better off buying a better motorcycle battery charger.

Overall, the NICHE 519-CAB2228T is a great battery for powering your Polaris Sportsman 500. It’s highly durable, maintenance-free, and will give you plenty of power to run all your accessories.

4. Chrome Battery YB14A-A2

The YB14A-A2 is one of the best batteries for your Polaris Sportsman 500 when it comes to price. With 14 Ah and 190 CCA, it’s a very powerful battery that won’t break the bank.

At first glance, the YB14A-A2 appears to be very similar to the Pirate Battery 14A-A2 that we reviewed earlier. However, there are some differences between the two batteries that prove very important.

While the Pirate Battery 14A-A2 delivers a slightly higher CCA at 210, the YB14A-A2 only delivers 190. However, with a full 14 Amp Hours of power, the YB14A-A2 bests the Pirate Battery in terms of reserve power and costs a bit less.

So, if you’re looking for an affordable battery with plenty of power, the YB14A-A2 from Chrome Battery is a great choice.

How To Buy The Best Battery for Polaris Sportsman 500

Before we let you go, let’s take a look at what you should look for when buying a battery for your Polaris Sportsman 500.

Cold Cranking Amps (CCA)

This is the best indicator of a battery’s ability to start your engine in cold weather. CCA can be found printed on the battery, and the higher the number, the better.

For example, a battery with 210 CCA will start your engine in colder weather much easier than a battery with only 100 CCA.

Reserve Power/Amp Hours (AH)

This indicator tells you how long your battery can continue to power your accessories after the engine has been shut off.

For example, a battery with 12 AH can continue to supply a constant 1 Amp for up to 12 hours.

This is important to know because if you’re planning on using your lights or other accessories for a long time after the engine has been turned off, you’ll want a battery with high AH.

Battery Type

There are two main types of batteries that you can choose from when buying a battery for your Polaris Sportsman 500: AGM (Absorbent Glass Mat) and lead-acid.

Lead acid batteries are the older technology and have been used in vehicles for many years. They require maintenance, such as adding water to the cells, and are not as durable as AGM batteries.

AGM batteries, on the other hand, are newer technology and don’t require any maintenance. They’re also more durable and can withstand being used in rough conditions with frequent shock and constant vibrations.

So, when choosing a battery for your Polaris Sportsman 500, we recommend going with an AGM battery.


Of course, price is always a factor to consider when making any purchase. However, when it comes to batteries, we recommend not skimping on price.

This is because a battery is a very important part of your vehicle, and you don’t want to risk damaging your engine or accessories by installing a bad battery.

When it comes to batteries, it’s best to buy from a reputable manufacturer with a proven track record of providing quality products.

If you do your research and buy a quality battery, it will last you for many years and save you money in the long run.
