How to Charge ATV Battery: A Complete Guide

by Phil Borges // in ATV

Riding an ATV in the great outdoors is an exhilarating experience, but if your ATV battery dies, the fun stops. A dead battery can be frustrating, but the good news is that it’s easy to charge an ATV battery. In this guide, we’ll show you how to charge your ATV battery and answer some common questions related to charging ATV batteries.

Can you charge an ATV battery with a car battery charger?

Yes, you can charge an ATV battery with a car battery charger. However, you need to make sure that the car battery charger is compatible with the ATV battery. ATV batteries typically have lower voltage and amperage ratings than car batteries, so you need to make sure that the car battery charger can provide the correct charging current. It’s recommended to use a smart charger designed specifically for ATV batteries, but a car battery charger can be used in a pinch.

Does an ATV charge its battery?

Some ATVs have a charging system that charges the battery while the engine is running, but not all ATVs have this feature. If your ATV doesn’t have a charging system, you’ll need to charge the battery manually.

Can I charge ATV battery while connected?

It’s not recommended to charge an ATV battery while it’s connected to the ATV. The charging process can generate gas, and if the battery is connected, the gas can ignite and cause an explosion. Always remove the battery from the ATV before charging it.

How long does it take to charge an ATV battery?

The charging time for an ATV battery depends on the battery’s capacity and the charger’s amperage rating. A standard ATV battery typically has a capacity of 12 volts and 7-10 amp-hours. A smart charger designed for ATV batteries can charge a standard ATV battery in 2-4 hours. If you’re using a car battery charger or a trickle charger, the charging time will be longer.

Steps to Charge an ATV Battery

Now that you have some basic knowledge about ATV batteries, let’s take a look at the steps to charge an ATV battery.

  1. Remove the battery from the ATV. Make sure the ATV is turned off and the key is removed.
  2. Clean the battery terminals with a wire brush or a battery terminal cleaner. This will ensure a good connection between the battery and the charger.
  3. Connect the charger’s positive cable to the positive terminal of the battery and the negative cable to the negative terminal. Make sure the cables are securely attached.
  4. Set the charger to the correct voltage and amperage rating for the battery. If you’re using a smart charger, it will automatically adjust the settings.
  5. Turn on the charger and let it charge the battery. Monitor the charging process and check the battery’s voltage and amperage periodically. If the battery gets too hot, stop the charging process and let it cool down before continuing.
  6. Once the battery is fully charged, disconnect the charger’s cables from the battery terminals. Reinstall the battery in the ATV and turn the ATV on to make sure the battery is working properly.


Charging an ATV battery is a simple process, but it’s important to follow the correct steps to ensure your safety and the longevity of the battery. Always use a charger designed for ATV batteries, and never charge the battery while it’s connected to the ATV. With these tips, you’ll be able to keep your ATV battery charged and ready for your next adventure.
