Benefits of ATV Batteries

ATV batteries are obviously smaller than standard car batteries. The voltage of ATV batteries ranges from 12.6 volts to 13.1 volts. A standard car battery is usually a volt higher than an ATV battery. The most common voltage for an ATV battery is 12 volts.

How to Charge and Maintain Your ATV Battery

ATV batteries need to be connected to a charger when they’re not being used. That will ensure their longevity and maintain their capacity. Not keeping a maintenance charge will lead to sulfation which is a battery’s sworn enemy and as a result, you might have to go through a costly replacement process. Do good by your battery for it to do good by you on the long run.

When you purchase a new battery, do not use it right away. Instead, you should trickle charge it for around 10 hours. Depending on the size of the battery, the amperage will be anywhere between 1 to 3 amps. This whole process is called the activation process. Batteries that aren’t properly activated usually suffer from capacity losses.

ATV Battery Types

The majority of battery types available are just variants or derivatives of two basic battery types, conventional Lead Acid batteries, and Absorbed Glass Mat batteries. But for the sake of expanding your overall knowledge of batteries, here’s a list of the most common battery types that you will find on the market.

Lead Acid Batteries

These old school batteries rose to prominence in the 1980s by Honda. This is one of the most popular and affordable types of batteries but they are also the most cumbersome. You have to fill the battery with acid yourself and charge it overnight. Also, the dry plates on these batteries can be easily damaged so you have to top it off with distilled water.

AGM Batteries

These batteries are an extremely popular choice for quite a number of reasons. They are filled, charged and ready to go. This type is more efficient than the conventional type as it is able to resist vibrations, power loss, and temperature vibrations while also being smaller and lighter. On the flipside, AGM batteries are slightly more expensive than their conventional counterparts.

Maintenance Free Batteries

This battery type is basically a derivative of a lead acid battery that is delivered with a pre-measured amount of acid. All you need to do is fill it, charge it and hit the road.

Gel Batteries

This type of batteries is filled with a gel matter that makes it more resistant to vibrations than an AGM battery. They are also smaller and lighter which as a result makes them more expensive.

Lithium Ion Batteries

This type of batteries is the most advanced one as of yet. An astounding combination of ultra lightweight and immense cranking amps. Many opt for this type when aiming to achieve the lightest vehicle weight possible. The downside of Lithium Ion batteries is that they are the most expensive on the market.

What Type of ATV Battery Should You Choose

For an ATV, the most common choices are the Lead Acid batteries and the AGM batteries. Both types can vary in quality and performance depending on the manufacturer, but the clear win goes to AGM batteries. AGM batteries have higher capacity and power rating than a conventional battery while also being smaller and lighter. They require low maintenance if none at all.
