Can Golf Cart Batteries Be Refurbished?

Like any other battery, golf cart batteries will eventually need to be replaced. But what happens to the old batteries? Can they be refurbished and reused, or are they destined for a landfill after just one season of use?

Yes, you can refurbish golf cart batteries. Reconditioning golf batteries is a great way to save money and extend their lifespan.

This article will show you how to refurbish golf cart batteries. We’ll also share some tips on prolonging the life of your golf cart batteries.

Golf Cart Battery Refurbishment

A golf cart battery is a type of lead-acid battery. These batteries are made up of six cells, each containing a lead anode and a lead dioxide cathode. The cells are filled with an electrolyte solution of sulfuric acid and water.

The sulfuric acid reacts with the water to produce electrons flowing from the cathode when the battery is used. This flow of electrons provides the power needed to run the golf cart.

Golf cart batteries are typically two 12-volt batteries connected in series to provide 24 volts. However, some golf carts may have four to eight-volt batteries instead.

Now, refurbishing a golf cart means something far more exciting: giving new life to a used battery and its process. A golf cart battery comprises six cells, each with a lead anode and a lead dioxide cathode. These cells are filled with an electrolyte solution of sulfuric acid and water.

When you refurbish a golf cart battery, you’re essentially reconditioning the cells so they can hold a charge again. This process can be done in a few different ways, but the most common method is to use a golf cart battery charger.

Most golf cart battery chargers have two settings: “charge” and “trickle.” The charge setting will bring the battery up to full voltage, while the trickle setting will maintain the battery’s current voltage.

Process of Refurbishing a Golf Cart Battery

To refurbish the battery, you will need the following instruments;

  • Safety goggles
  • Protective gloves
  • Soft brush
  • Baking soda
  • Distilled Water
  • Flathead screwdriver
  • Epsom salt
  • Turkey Baster
  • Battery charger for your golf cart battery
  • Wrench to loosen the battery terminals.

Refurbishing a golf cart battery is complex and exciting and can be fascinating. These are the steps to follow;

  • Retrieve the golf cart battery. You will need the following instrument to retrieve it;
  • Clean the battery. You can do this with a brush and some soap and water. Be sure to rinse the battery well after washing it.
  • Check the water level. You will need to add distilled water if the level is low.
  • Fill the cells with distilled water until it reaches the fill line. Do not overfill the cells as this can damage the battery.
  • Add 12% to 15% of Epsom salt relative to distilled water; dissolve the salt in distilled water, and add it to the battery cells.
  • The Epsom salt will help clean the battery cells and remove any build-up on the electrodes.
  • Attach the battery charger to the golf cart battery. Be sure to follow the manufacturer’s instructions when attaching the charger.

Benefits of Refurbishing a Cart Battery

There are several benefits of refurbishing a golf cart battery.

Refurbishing a Cart Battery Saves Money

The cost of buying a new golf cart battery ranges between $100 and $300. The cost of refurbishing a golf cart battery is a fraction of that, making it a much more economical choice.

Refurbishing is Environmentally Friendly

Refurbishing a golf cart battery is better for the environment than buying a new one. The mining and production of lead-acid batteries are very energy-intensive and generate a lot of pollution.

When you refurbish a golf cart battery, you’re reusing the lead and other materials, which reduces the environmental impact.

Refurbishing Extends Battery Life

Refurbishing a golf cart battery is a convenient way to extend its life. If you have the time and patience, it’s a relatively simple process. Plus, you don’t have to go through the hassle of buying a new battery and disposing of the old one.

Signs of a Weak Golf Cart Battery

Several signs indicate a golf cart battery is weak and needs to be replaced or refurbished.

Golf Cart takes Longer to Start

When batteries are new, they have a full charge and can create a golf cart quickly. However, as batteries age, their charging capacity decreases. As a result, they may take longer to create a golf cart or other vehicle. If you notice that your golf cart is taking longer to start, it’s essential to have the battery checked by a professional to check the battery water level.

Battery did not Pass a Voltage Test

You can use a voltmeter to test the voltage of the battery. A fully charged golf cart battery should have a voltage of around 6 volts. If the voltage is below 6 volts, the battery is likely weak and needs to be replaced.

Sulfate Build-up on Battery Terminals

If you notice a white, powdery substance on the battery terminals, it’s a sign of sulfate build-up. This can prevent the battery from charging correctly and cause it to fail prematurely.

Corroded Battery Terminals

Corroded battery terminals are often caused by exposure to moisture or chemicals. Over time, this can damage the terminals and cause them to break down. This can then lead to a loss of power, making it difficult for your golf cart to start and run properly. In some cases, the corrosion can also cause a fire.

Headlights are Dimmer than Usual

If the headlights on your golf cart are dimmer than usual, it’s a sign that the battery is weak and needs to be recharged or replaced.

Age of the Battery

The age of the battery is also an indicator of its condition. Lead-acid batteries typically last between three and five years. If your battery is older than that, it likely needs to be replaced or refurbished.

No “Get Up and Go”

When it comes to golf carts, a few things can indicate that the battery may be weak. One of those things is a lack of “get up and go.” If the cart isn’t moving as fast as it used to or struggling to make it up hills, that’s usually a sign that the battery is weakened and needs to be replaced.

Repeated Draining and Recharging

If you find yourself having to recharge your golf cart battery more often than usual, it’s a sign that the battery is not holding a charge as well as it used to. This could be due to sulfate build-up, corrosion, or simply age.

Acid Level is Low

One of the signs of a weak battery is low acid levels. If the acid level in a battery is too low, it will not generate enough power to run the golf cart. As a result, the cart may move slowly or even come to a stop in mid-round. Low acid levels can also cause damage to the battery itself, so it is essential to monitor the acid level and take steps to keep it topped up.

How To Extend Golf Cart Battery Life

You can do several things to protect your golf cart battery and extend its life. Here are the things you can do.

Keep the Battery Clean

One of the best ways to protect your golf cart battery is to keep it clean. Saving the battery lean includes cleaning the terminals and posts and keeping the area around the battery free of dust and debris.

Store in a Cool and Dry Place

It’s also essential to store your golf cart battery in a cool, dry place. Extreme temperatures can damage the battery and shorten its lifespan.

Charge Regularly

Another way to protect your golf cart battery is to charge it regularly. Charge regularly helps prevent sulfate build-up and keeps the battery cells from going through too many charging cycles, shortening their lifespan.

Use a Battery Maintainer

A battery maintainer is a device that connects to the battery and keeps it charged. This is an excellent way to protect your golf cart battery if you don’t use it often or if you’re going to be storing it for an extended period.


While you can refurbish golf cart batteries, it is essential to keep in mind that this process may not significantly extend the battery’s life. In addition, it is necessary to be aware that refurbishing a golf cart battery can be a time-consuming and expensive process.

For these reasons, many people simply choose to replace their golf cart batteries when they show signs of wear and tear. However, if you are interested in refurbishing your golf cart battery, following the steps above will get it done.
