Can Golf Cart Batteries Be Refurbished?

Golf cart batteries, on average, can last 4 to 5 years if you can maintain them properly. You may experience issues with them over time, such as increased charging time or reduced range owing to low voltage. Many people believe that the battery should be replaced at this point; however, this is not always the case. So, when you think “can golf cart batteries be refurbished”, then the answer is conditional YES.

This means you can refurbish your golf cart batteries if they are not fully dead. There is also a limitation to doing it. You only can refurbish it up to a certain extent.

Can Golf Cart Batteries Be Refurbished? The Right Answer

When you want to know the precise answer to the question ‘can golf cart batteries be refurbished’, then we can simply say YES. So, we always recommend that you try to refurbish your golf cart batteries first before buying a new one. This is because it is both cost-effective and environmentally beneficial. Cleaning the corrosion on the terminals and refilling the water with a solution of distilled water and Epsom salt can be done to repair the golf cart battery.

Fortunately, it is a simple procedure that, if carried out correctly, will increase the life of your battery. And, as a result, it can save you money on battery replacement.

Most golf carts have 6-volt lead-acid batteries, which are miniature vehicle batteries. However, due to negligence and bad storage, golf cart batteries do not always last as long as they could. You may extend the life of a golf cart battery by reconditioning it. When the cart is not in use, make sure all electrical equipment is turned off.

When Should You Refurbish the Battery in Your Golf Cart?

You can do several things before going to refurbish your golf cart battery. These are below:

  • The charger, rather than the battery, can occasionally be the source of the problem. Charge a different battery to see if this is the case.
  • If your charger is in fine working order, it’s possible that your battery has been damaged or is on its way out. If the voltage is too low, you know it’s time to recondition the battery. A voltmeter reading of 50 to 52V indicates that the batteries are healthy.
  • If it shows less than 48V after a full charge, the battery should be replaced or refurbished as a whole. Although the issue could be with a single battery, the failure of one frequently signals the arrival of another. When it’s time for a refurbishment, it’s preferable to replace every battery in the set.
  • If you’ve observed that it takes much longer to charge than it used to and that it doesn’t hold a charge as well, you probably have a battery that needs to be refurbished.
  • A “shutter” when driving, which feels like the brake is being pressed repeatedly at a quick rate, is another symptom that the battery is at a low voltage.
  • Any or all of these indicators indicate that you should inspect the battery cells for damage before deciding whether or not to refurbish them. Refurbishing a battery reduces waste and prevents costly replacements. Thus it’s always preferable to do so before discarding it. Although repairing a battery can be beneficial, it is not a long-term solution and will only last a year or so.

Benefits of Refurbished Golf Cart Batteries

When a lead-acid battery fails, it is not advisable to toss it out somewhere. It’s terrible for the environment since the chemicals it contains have negative consequences. As a result, the best approach to extend its life is to renovate it.

If correct usage is maintained, a remanufactured golf cart battery can have its life extended by more than a year. You’ll have the same procedure, and your golf cart will be back on the road in no time.

Refurbishing golf cart batteries is claimed to be the most cost-effective method of extending their life. It is not only environmentally friendly, but it is also the most efficient and cost-effective solution for restoring your cart’s battery life and allowing you to use it again.
The Sulfation Issue with Golf Cart Batteries

Sulfation, or a build-up of sulfate crystals, will occur in every lead-acid golf cart battery at some point. Too much of it will result in early battery failure, necessitating refurbishment or replacement. Overcharging, undercharging, or discharging the battery too low can speed up the sulfation process.

By reducing the length of a full charge, raising the risk of acid overflow, and diminishing the amount of active material in the battery, the accumulation might cause early battery failure. These issues not only limit the battery’s lifespan but also significantly reduce its performance.

Fortunately, the major purpose of the refurbishing procedure outlined below is to remove the sulfate buildup that causes the plates to touch, eventually shorting out and preventing the battery from properly charging.

Ways of Refurbishing a Golf Cart Battery

Protect yourself with an apron, gloves, and safety glasses before starting the refurbishing procedure. Distilled water, baking soda, Epsom salt, a wire scratch brush, a flathead screwdriver, a wrench, and a funnel are all necessary tools.

If you discover any damage to the battery, such as acid leaking, your only alternative is to replace it altogether; refurbishing it is not an option at that point.

First Step

Check the battery cells’ water levels. If the battery isn’t full, don’t go any further with this procedure until it is.

Second Step

Disconnect and remove the battery with a wrench.

Third Step

Mix 2 teaspoons baking soda with 1 quart of water to make a paste. Scrub the battery terminal posts with the wire brush to remove any corrosion buildup. If the corrosion is really severe, sandpaper can be used.

The Fourth Step

Rinse the battery as thoroughly as possible without getting any water on it, then dry it entirely.

The Fifth Step

Remove the battery covers with a flathead screwdriver and drain the battery into a suitable container.

The Sixth Step

Make a solution of distilled water and 15-17 percent Epsom salt. To properly dissolve all of the salt, slightly reheat the distilled water.

The Seventh Step

Epsom salt solution should be used to refill the battery cells. Replace the battery caps and secure them in place.

The Eighth Step

Connect the battery to a smart trickle charger after it has been cleaned and refilled with a fresh solution. It should take about 12 hours to charge completely.

The Ninth Step

Test the battery with a multimeter, voltmeter, battery load test, or hydrometer once it has been fully charged. If the voltage is still not correct, it must be changed.

How to Make Your Golf Cart Batteries Survive Longer?

Consider the following guidelines to help your golf cart batteries survive as long as possible:

Make a Quality Investment

Choosing the cheapest golf battery could have long-term effects, so invest in a high-quality battery.

Make Use of Extra Items

Seal nuts, bolts, terminals, and wire lugs with a sealer. Cover exposed wires with submersible rubber tape. An extra layer of corrosion resistance can be added to the terminals by using petroleum jelly.

Water Levels Should be Checked

The battery’s lifespan is shortened by overwatering and submerging it. Underwatering exposes the tops of the plates, causing more damage.

Charge at Appropriate Time

Experts advise charging the battery once it reaches 50% capacity and not running it until it is completely depleted. This reduces the amount of heat generated by charging and ensures a longer battery life.


So, you now know everything about “can golf cart batteries be refurbished” or not. Unless the battery has been damaged to the point that it can no longer be used, there is a strong chance you may revive it and give it a new life.

Many individuals consider the procedure of refurbishment to be reasonably simple and a far superior alternative to replacing it. Because new golf batteries may cost anywhere from $800 to $1500, it is a good idea to see whether the battery can be refurbished before discarding it.
