Buyer's Guide for UTV Batteries and Chargers: Helping You Shop!

Why Go With an Aftermarket UTV Battery In the First Place?

Sure, batteries technically all run the same when they’re working, but that’s just the problem: what happens when stock quits? Frankly, stock UTV batteries are engineered to be as cheap as possible while meeting minimum specs. On the other hand, Aftermarket AGM (Absorbed Glass mat) batteries flip this equation by using advanced technology where the electrolyte is absorbed into fiberglass mat separators rather than sloshing around freely. This design delivers several critical advantages for side-by-side applications.

Especially if you’re running a lot of heavy accessories, you’re going to want some major reserve capacity, which is where AGM and Odyssey batteries really stand out. They will also recharge quicker than your standard UTV battery, and they’ll perform way better in cold weather. Long story short? The aftermarket UTV batteries and chargers in our selection were intentionally designed to fill every gap left by stock. 

Your UTV Battery Specs Crash Course

We’re well aware that many of you have already acquired savant-level knowledge of all things UTV batteries (hopefully not the hard way), but for everyone else, knowing what the numbers actually mean is crucial to making an informed purchase. For example, if you have no idea what CCA (Cold Cranking Amps) is, you won’t know which of the two UTV batteries you’re considering performs better in the cold. Higher CCA numbers mean easier starts in cold weather, since it’s a measure of how much current the battery can crank out at zero degrees Fahrenheit (yikes!).

Amp Hours (Ah) is your battery’s capacity. Simply put, this is the amount of time your battery can meet certain output thresholds before it needs a recharge. If you’re running accessories with the engine off, this is most definitely an important figure. Finally, reserve capacity tells you how long the battery can maintain before voltage drops below a certain level. This may be even more important for riders who want to run lots of accessories! (And you know you do.) 

Tips and Tricks for Dual UTV Battery People

Look, there’s no law that says you have to run your light bars, winches, air compressors and other accessories on a single battery. When the load is simply too much, it’s time to seriously consider a dual battery setup. To make life (much) easier for you in this regard, we’ve got a complete range of dual battery kits for UTVs. 

Our kits come with absolutely everything you need to run a dual battery UTV setup, including the added battery, mounting tray or box, isolator and all the hardware you’ll need. Even if you don’t have an extensive accessory setup, running with a second UTV battery can get you home in the event of a failure.

UTV Battery Frequently Asked Questions

How long should I expect a UTV battery to last in the first place?

If we’re talking high-quality AGM battery, you can get a solid three to five years if you properly take care of it. Some batteries can last even longer.

Will a standard automotive battery charger work on my UTV battery?

The more modern “smart” chargers usually work fine with UTV batteries, but be very careful with older chargers that don’t regulate the current, as going too high on the voltage can damage your battery. 

Will I have to trade up for a better alternator?

This is a case-by-case thing; it depends on just how much load you’re putting on that battery. Stock alternators can give you between thirty and fifty amps, which can run dual batteries in most cases if you don’t have a ton of accessories. Otherwise, you will need an upgrade.
