How Long Does an ATV Battery Last?

You can expect your ATV battery to last 3 to 5 years.

It’s not uncommon for some people’s ATV batteries to only last a year; I’ll explain why that happens below. It’s also possible to go beyond 5 years, and I’ll show you how to do that too.

How To Get The Most Life Out of your ATV battery

The single best thing you can do to get the most life out of your ATV battery is to keep it on a smart charger when you’re not using it.

The reason why your battery dies after only a year is that you’re not using the ATV enough. Many people only use their ATV only a few months out of the year. If a battery is not being used, it slowly dies due to a build of sulfide on its plates. The more of a build-up, the less power the battery has to give.

Since ATV batteries are so small this build-up happens quicker than say for your car.

This is why your ATV battery keeps draining; I go over this in more details here.

You can use a regular car charger, but it’s more beneficial that it’s a smart charger. A smart charger can turn itself on and off as it’s needed so it won’t overcharge the battery.

How Long To Charge an ATV Battery?

It takes several hours to charge an ATV battery. For best results, I recommend letting it charge overnight or till the battery charger says it’s done.

How To Properly Charge an ATV battery

You may have to remove a seat or pull off some cosmetic panels to get to your battery.

This video below does a great job showing you how to change an ATV battery.

Tip: If your battery wires on your ATV are dirty like the ones in the video, clean them with a fine-grit sandpaper. This will help make a better connection to the battery.

You must follow this order when hooking up a battery charger.

  1. Plug in the battery charger to the wall outlet.
  2. Connect the red positive (+) cable of the battery charger to the red positive (+) of the ATV battery.
  3. Connect the black negative (-) cable of the charger to the black negative (-) of the ATV battery.
  4. Wait for the battery charger to let you know it’s charging.

If the battery charger gives a fault or never charges, then the battery is dead and must be replaced.

How To Remove Charger From Battery

When you remove the charger from the battery, make sure to disconnect the negative cable first to reduce sparks and keep from screwing up the charger and the ATV electronics.

How To Fix A Dead ATV Battery

There is no magic cure to bring back a dead ATV battery. But there does exist some battery chargers that can pulse it back to life.

To be honest, these pulse chargers don’t always work, and when they do, it can take days. It’s not worth the effort, especially when you can go to Walmart and get a cheap ATV battery.

For those that want to fix a dead ATV battery, this video will show you how.

Does An ATV Charge It’s Own Battery?

Unlike a car, an ATV does not have an alternator.

An ATV only has a stator, the difference is that a stator only generates enough energy to maintain power, where an alternator will generate more to charge a battery. An alternator is bigger and adjusts to the power needs where a stator is smaller and gives the best it’s got (which is usually only enough to keep the engine running).

So riding your ATV in the hopes to charge it’s battery won’t actually charge much. If you leave it for a few hours, the battery will be flat again.

The only way to charge an ATV battery is to use a battery charger.

Can You Jump Start An ATV Battery?

Yes, that means the batteries you get at Walmart are not the best. To be honest, if you keep them on charge when you’re not using them, any battery can last a long time.

Where To Charge ATV Battery?

The best place to charge an ATV battery will be somewhere that is open with proper ventilation and dry.

All batteries give off gas when they’re charging, and this gas is hydrogen (flammable). The gas they give off is not a lot, but it’s still smart to play it safe.

Storing the battery on concrete is a myth. Cold temperatures do destroy batteries, especially the smaller ATV batteries.
