If you’re here, then you probably own a Generac generator and are dealing with some battery problems. 

Don’t worry, you’re not alone! Battery issues are a common problem for generator owners, but luckily, they’re usually pretty easy to fix. 

In this post, I’ll go over some common battery problems and give you some tips on how to fix them.

Get your necessary tools and let’s get started.

Why Your Generac Generator Battery Might Be Having Issues

First, let’s talk about why your battery might be having issues. The most common reason is simply that the battery is old and needs to be replaced. 

Generac recommends replacing the battery every two to three years, so if it’s been longer than that since you last replaced it, then it’s probably time for a new one.

But there are other reasons your battery might be having issues, including:

  • Improper maintenance: That’s if you’re not using your generator regularly, the battery can lose its charge. To avoid your generator from losing its charges, you should maintain it properly by at least running your generator for a few hours to keep your battery charged at all times.
  • Dirty or loose connections: Another reason is that the battery connection isn’t fixed properly, that if you have checked if the battery is charged and there are any issues with it. 

Specific Generac Battery Problems You Might Be Experiencing

For you to fix a problem, you will need to know the type or specific problem you are facing. And that’s true for Generac generators.

So, here are some common battery problems you might be experiencing with your Generac generator:

Problem #1: The Battery Won’t Hold a Charge

If your battery won’t hold a charge, then it’s probably time to replace it. However, before you do that, make sure to check the connections to make sure they’re clean and tight. If the connections are dirty or loose, then that could be causing the problem. You can clean the connections with a wire brush and tighten them with a wrench.

Problem #2: The Battery Is Leaking

If your battery is leaking, then that’s a serious problem and you should stop using your generator immediately. A leaking battery can be dangerous, so you’ll need to replace it as soon as possible. Make sure to wear gloves and goggles when handling the battery to protect yourself from any acid that might be leaking out.

Problem #3: The Battery Is Dead

If your battery is completely dead and won’t even hold a charge, then it’s time to replace it. But before you do that, make sure to check the voltage with a voltmeter. If the voltage is low, then you might be able to recharge the battery. If the voltage is normal but the battery still won’t hold a charge, then it’s time to replace it.

How to Clear Battery Problem on Generac Generator

Now that you know what battery problems you might be experiencing, let’s talk about how to fix them.

Solution #1: Replace the Battery

If your battery is old or completely dead, then the best solution is to replace it. You can purchase a replacement battery from a Generac Generator third-party retailer. 

Make sure to follow the manufacturer’s instructions for installing the new battery. But for me, If you are using any Standby Generac generator that’s up to 22kw, I will recommend you go for the Generac 5819 Model 26R Wet Cell Battery For All Air-cooled Standby Generators (you can check it out on Amazon).

Solution #2: Clean and Tighten the Connections

The second solution can be followed if only your generator’s battery is not completely dead, but the connections are dirty or loose, then, that’s the time you will have to clean and tighten the connections to help solve the problem. Use a wire brush to clean the connections and a wrench to tighten them.

Solution #3: Recharge the battery

Lastly, if your battery is low but not completely dead, then you might be able to recharge it. You can use a battery charger or charge it while the generator is running. Make sure to follow the manufacturer’s instructions for charging the battery (that’s by using the right voltage charger for the generator’s battery).

Final Thought 

Battery problems are a common issue for Generac generator owners, but they’re usually easy to fix. If you’re experiencing battery problems, you can try these solutions: replace the battery, clean and tighten the connections, or recharge the battery. 

But if none of these solutions work, then it might be time to call in a professional. But hopefully, with these tips, you’ll be able to keep your Generac generator running like new for years to come.

So, after you have fixed your battery issues, you will want to reset your generator and also fix other issues if needed.
