Will Golf Cart Batteries Freeze In Winter? What You Need to Know!

Golf carts have become a popular mode of transportation for many individuals, whether it’s for leisurely rides around the neighborhood or for use on the golf course. 

But as temperatures begin to drop, concerns about whether golf cart batteries will freeze start to arise. Freezing temperatures can cause many issues with batteries, from reducing their performance to causing irreversible damage. 

In this blog post, we’ll explore the topic of golf cart batteries and freezing temperatures in depth, discussing the risks and potential solutions to ensure your golf cart stays running smoothly throughout the winter months. 

Understanding How Batteries Work in Golf Carts

Rechargeable batteries power golf carts’ electric engines. Lead-acid batteries—the most prevalent form of rechargeable battery utilized in automobile applications—make up these batteries.

While the golf cart is in operation, the chemical energy stored in the battery is transformed into electrical energy.

A chemical process that stores energy in the battery’s cells occurs when an electrical current is sent through the battery during charging.

While the golf cart is in operation, electricity is extracted from the battery and supplied to the motor, transforming it into mechanical energy and propelling the cart forward.

The chemical process inside the battery is reversed when energy is pulled out of it.

Can Golf Cart Batteries Freeze?

Will Golf Cart Batteries Freeze In Winter

Indeed, if they are not properly safeguarded and maintained, golf cart batteries can freeze.

Typically, lead-acid batteries used in golf carts include a liquid electrolyte solution that, if the temperature falls below a particular level, might freeze.

The specific gravity of the electrolyte solution, which is influenced by the battery’s temperature and sulfuric acid content, is what determines the lead-acid battery’s electrolyte’s freezing point.

With a fully charged battery with a specific gravity of 1.265, the electrolyte typically freezes at a temperature of around -40 degrees Fahrenheit (or -40 degrees Celsius).

The battery may suffer harm if it gets too cold—below the electrolyte’s freezing point, that is. When freezing, the electrolyte expands.

What happens when golf cart batteries freeze?

As the water in golf cart batteries freezes, it expands as it becomes ice, causing the cells to swell and perhaps fracture.

This might impair the battery’s functionality and cause harm. When a golf cart battery freezes, these are some potential outcomes:

Reduced capacity

Golf cart batteries can have their capacity reduced by freezing conditions, which means they won’t keep a charge as well as they typically would. Performance may suffer, and run times may be shortened as a result.


The expansion and contraction of the battery’s lead plates brought on by freezing might harm the battery and result in sulfation.

Sulfation is the formation of sulfate crystals on the lead plate surface, which can decrease the battery’s capacity to store a charge.

Cracked battery case

The battery shell may shatter as a result of the electrolyte (the liquid within the battery) freezing, which may result in leaks and other damage.

Inability to charge

Golf cart batteries can freeze if they aren’t utilized during cold weather, which can cause long-term battery damage. To prevent golf cart batteries from freezing, try any of the following methods:

Tips For Preventing Golf Cart Batteries from Freezing

Golf cart batteries, as you undoubtedly know, can freeze if they are left unused in cold weather, which can result in permanent battery damage. But these are some ways to keep golf cart batteries from freezing:

Keep the batteries charged

A fully charged battery has a lower chance of freezing than one that is just half charged. Before keeping the batteries for a lengthy amount of time, make sure they are properly charged.

Store the batteries in a warm place

If at all feasible, keep the batteries in a warm location like a heated garage or a heated storage shed. The risk of the batteries freezing can be reduced by keeping them in a warm atmosphere.

Insulate the batteries

In order to prevent the battery from freezing, a battery warmer is a device that warms the battery. Batteries for golf carts may be warmed up using a battery warmer that is available.

Use a battery warmer

A gadget called a battery warmer warms the battery to prevent it from freezing. You may buy a battery warmer made especially for golf cart batteries.

Use a battery tender

A battery tender is a tool that keeps a battery charged while it is being stored. This can assist in keeping the battery from freezing and extend the battery’s lifespan.

Check the water level

When storing the batteries, make sure to check their water level. To raise the water level to the appropriate level, if it is low, add distilled water.

Low water levels might make the battery more susceptible to freezing and damage.

How do you keep golf cart batteries in the winter?

Here is a step-by-step guide on how to keep golf cart batteries in the winter. These instructions will help you make sure your golf cart batteries are appropriately stored during the winter, which will increase their longevity and performance.

Step 1: Clean the batteries

Golf cart batteries need to be carefully cleaned before being put up for the winter.

Using a wire brush and a mixture of baking soda and water, clean any dirt, debris, or corrosion from the battery terminals and cable connections to complete this task.

Step 2: Check the water level

It’s crucial to check the water level in each cell if your golf cart batteries are flooded with lead-acid types.

If necessary, add distilled water to each cell to raise the water level to the suggested level.

Step 3: Charge the batteries

Before putting the batteries away for the winter, fully charge them. Sulfation, which might happen if the batteries are stored in a partially charged condition, is averted thanks to this.

Step 4: Disconnect the batteries

Remove the negative cable first, then the positive cable, to disconnect the batteries from the golf cart.

This stops the batteries from experiencing parasitic drains, which can happen even while the golf cart is not in use.

Step 5: Store the batteries

Keep the batteries in a calm, dry environment that is protected from freezing temperatures.

Preferably, the temperature should be between 32°F and 80°F. Be sure that the batteries are correctly stored and are not piled on top of one other.

Step 6: Check the batteries periodically

Inspect the batteries occasionally during the winter to verify that they keep their charge.

If the batteries are exhibiting indications of discharge, charge them thoroughly before storing them again.


Can you leave golf cart batteries outside in winter?

In order to avoid damage from discharge, it is advised to maintain your golf cart’s lead-acid batteries charged while it is stored during the winter. For exact directions, consult the manufacturer’s instructions.

Should I keep my golf cart plugged in all winter?

It is advised to maintain lead-acid batteries charged for winter storage if your golf cart has them to avoid harm from discharge. For precise directions, consult the manufacturer’s instructions.

Are lithium golf cart batteries damaged by freezing?

Extreme cold can harm lithium golf cart batteries, although they are less prone to freezing damage than lead-acid batteries. Follow the manufacturer’s instructions for usage and storage.

Final Thoughts

While golf cart batteries can freeze in certain circumstances, most golf cart owners don’t experience this often. Maintaining your batteries properly can help protect them from freezing and increase their lifespan.

This includes keeping them charged and putting them in a cool, dry location during the off-season.

To prevent damage from freezing conditions, extra measures like utilizing a battery warmer or removing the batteries for indoor storage may be essential if you do reside in a colder region or want to keep your golf cart for a long length of time during the winter.

Therefore, by knowing how to maintain and care for your golf cart batteries properly, you can make sure they continue to function well and deliver dependable.
