Spring is on the way and you know what that means; it's time to start prepping your ATV for another exciting season. When it comes to caring for your ATV, maintaining your battery is key. Today we'll be taking a look at the different types of ATV batteries. We'll share some tips to help you determine when your battery needs replacing and review a few ways to help you prolong your battery's life.
ATVs run on powersport batteries like those found in motorcycles, personal watercraft, snowmobiles and other recreational vehicles. There are three different types of powersport batteries available to ATV owners: flooded lead acid, AGM (short for Absorbed Glass Mat) and lithium iron phosphate. Here is a basic breakdown of the types of ATV batteries available at Batteries Plus.
As you can see from the breakdown above, different types of ATV batteries have different lifespans. On average, a flooded lead acid ATV battery will last you between two and three years. An AGM battery averages out to between three and five years. Lithium iron phosphate batteries outperform the other two types and are capable of lasting as long as eight to ten years. Keep in mind that these are averages and there are a number of additional factors that affect the life expectancy of an ATV battery, including how the battery is stored, how well it is maintained and what climate the battery is used in.
ATVs have their own built-in charging systems, however the current they provide isn't very high. Because of this, you might have to rely on an additional battery charger. When selecting a battery charger for your ATV, make sure that the model you choose is compatible with both the voltage and chemistry of your battery. The other important thing to remember is that you want to avoid under and overcharging your battery, both of which will shorten its overall lifespan. Charging times will vary between batteries and will depend on the type of charger you have.
There are several different types of battery chargers available for ATV owners. The key difference between them is how they apply current. Standard chargers apply a constant amount of current, while trickle chargers apply small amounts of current designed to charge your battery over a longer period of time. When using either of these options, it's important to monitor the charging process to avoid overcharging your battery.
If you're looking for something that won't overcharge your battery, you'll want to pick up a battery maintainer. Battery maintainers have built-in monitoring systems that will shut them off when your battery reaches its ideal voltage, then charge them back up again once the voltage drops.
In addition to regularly charging your battery, you'll also want to pay attention to how you store it when it isn't being used. It is best to store your battery fully charged in a cool, dry place. If the battery will be in storage for some time, be sure that you charge it regularly to keep it from getting too low. Battery maintainers are ideal for this purpose. Not only will they maintain your battery's charge, you can keep them connected indefinitely without any fear of overcharging the battery.

The other factor that will determine your battery's lifespan is climate. Excessive heat can cause the fluid inside your battery to evaporate, weakening the battery's charge and causing plate corrosion. Freezing temperatures cause your battery's energy capacity to drop, making it more difficult to turn over your engine and causing it to recharge much slower. Flooded batteries are particularly susceptible to severe temperatures, so if you live in a climate with extreme weather, you might want to invest in a better battery. Both AGM and lithium iron phosphate batteries perform well in high heat. Lithium batteries don't perform well in freezing temperatures though, so if you plan on riding your ATV in winter, an AGM battery is your best choice.
You can usually tell that your battery is dying based on its performance. If you notice that your battery doesn't last as long between charges, chances are your battery is going bad. A bad battery will also make it much harder to turn over your engine and may struggle to power your headlights, making them appear dimmer. You can also take a look at the exterior of the battery itself. Bulges, cracks and corrosion will all indicate a battery that is past its prime.
