Why Your ATV Battery Keeps Dying?

You’re probably wondering why your ATV battery keeps dying? It can be very frustrating to go out to your quad and see that it won’t start.

The reason why your battery dies is mostly to do with it sitting for too long. Unlike your car which you drive daily, your ATV may sit for weeks or months and the battery will go flat.

There are a few simple things you can do to keep your ATV battery from dying along with other things you need to keep in mind.

How To Keep ATV Battery From Dying?

To keep your ATV battery from dying there are two things you can do.

  1. Drive it more often.
  2. Or keep a smart battery charger on it when it’s going to sit for months.

The biggest reason ATV batteries die is that they’re not being used enough.

The battery needs to be kept active and unless you have the engine running or the battery hooked up to a smart charger the battery is slowly sulfating and dying. The sulfation won’t be noticeable for months but once it gets to a certain point the battery can’t come back and needs to be replaced. It’s just the nature of lead-acid batteries.

So if your ATV is going to be sitting for months it’s best to keep a smart battery charger (Amazon Link Ad) on it. It’s also best to remove the battery from the ATV when charging it.

Can You Jump An ATV Battery?

It’s best to avoid jumping your ATV battery from your car or truck.

Jumping your ATV battery from your vehicle while it’s running can fry the computer on your ATV. The batteries and alternators in cars or trucks are much larger and output more power than the electrical systems many ATVs can handle.

I repeat – Don’t jump your ATV battery with a Car or Truck!

You can, however, jump your ATV battery from a portable jump starter. Portable jump starters have come a long way, I personally have a “batteryless” one that charges off a dead battery. Yes, I know it sounds crazy but it’s a real thing and it works as shown in the video below. You can buy this jump starter here (Amazon Link Ad).

Be careful of the jumper wires when connected to a battery, they carry a lot of current and can really hurt someone who doesn’t know what they’re doing. If you don’t feel comfortable doing it then contact someone else with more experience like your local dealership. 

Riding the ATV will NOT Charge Your Battery

Running an ATV or Side By Side for a bit will not charge a dead battery.

Your car uses an alternator that charges the battery when running, but your ATV and Side By Sides use a stator. A stator is there to maintain a charge to power whatever is currently running and nothing more. Where an alternator is made to charge up a battery and keep it charged. The stator will keep the battery active and stop sulfation, but it’s not meant to charge the battery.

So riding around for a bit will not help much at all. Sure it will seem like the battery charged after riding for a bit but come the next day or a few hours the battery will be dead again.

No Power? Solar Charger?

If you don’t have power where you keep your ATV you can still keep the battery from dying.

Get yourself a 12-volt solar charger like this one here (Amazon Link Ad) and keep it on the battery when you’re not going to ride for months.

When it comes to solar chargers you want one that is 1 to 5-watts. Do not get a solar charger that is over 5-watts or you run the risk of destroying your battery.

If All Else Fails

If all else fail then you need to contact your dealer or local mechanic to see what is going on. The battery could be bad and the only way to know is to remove it and test it with a load tester.

You could have other problems like a rectifier is bad. A bad rectifier would mean the power your stator produces is not getting sent to the battery.

I’ve also seen fuses that go to the charging system fail too and that be the reason why an ATV battery won’t charge.

At this point, if you don’t know what you’re doing you need to take it to a dealership to get the problem worked out.
