Concerns about the high maintenance and replacement costs of these batteries are common among our customers. However, our goal is to change your perspective by providing you with comprehensive knowledge about golf cart batteries. We want to empower you to make informed purchasing decisions, eliminate your fears about replacement expenses, and help you choose the best battery options when the time comes for a replacement.

What Are Golf Cart Batteries? 

Golf cart batteries are deep cycle batteries specifically designed to power electric golf carts. These batteries are typically 6-volt or 8-volt batteries that are connected in series to provide the necessary voltage to power the cart. They are different from automotive batteries because they are designed to provide a steady flow of power over an extended period of time, rather than a burst of power for starting an engine. Golf cart batteries are essential for the operation of electric carts and are often referred to as the "beating heart" of the vehicle.

Electric golf carts typically operate at voltages of 36 or 48 volts, consuming between 50-70 amps of current while cruising at a speed of approximately 15 miles per hour. However, it is important to note that the current draw can increase significantly during acceleration or when navigating uphill terrain. This continuous demand for power necessitates the use of golf cart batteries that can provide a steady and high current flow for extended periods, ensuring that users do not become stranded during their outings.

How Do Golf Cart Batteries Work?

Golf cart batteries work by using a chemical reaction to convert chemical energy into electrical energy. They are typically deep cycle batteries, which means they are designed to provide a steady flow of power over an extended period of time, rather than a burst of power for starting an engine like automotive batteries.

Inside a golf cart battery, there are lead plates submerged in a solution of sulfuric acid called electrolyte. The lead plates are made up of two types: positive plates coated with lead dioxide (PbO2), and negative plates coated with sponge lead (Pb). These plates are arranged in a repeating sequence inside the battery.

When the battery is discharged, the chemical reaction between the lead plates, electrolyte, and sulfuric acid produces lead sulfate (PbSO4). When the battery is charged, the reverse reaction occurs, converting lead sulfate back into its original form of lead dioxide and sponge lead.

These chemical reactions produce electrons that flow through the battery terminals, creating the electrical current needed to power the golf cart.

It's important to note that golf cart batteries require proper maintenance, including regular charging and watering, to ensure their longevity and optimal performance.

In recent years, lithium golf cart batteries are becoming popular. Lithium golf cart batteries work by utilizing lithium-ion technology to store and release electrical energy. Unlike traditional lead-acid batteries, lithium batteries use lithium compounds as the active material in the electrodes.

Inside a lithium battery, there are typically two electrodes—the cathode and the anode—separated by an electrolyte. The cathode is usually made of lithium iron phosphate (LiFePO4), lithium nickel cobalt aluminum oxide (NCA), or lithium nickel manganese cobalt oxide (NMC). The anode is typically made of graphite or silicon-carbon composite.

During normal operation, lithium ions move back and forth between the cathode and the anode during charging and discharging. When charging, lithium ions are extracted from the cathode and inserted into the anode, resulting in the storage of electrical energy. Conversely, during discharging, lithium ions move back to the cathode, releasing stored energy in the form of electrical current.

Types of Golf Cart Battery: Lead-Acid VS LiFePO4

There are four main types of golf cart batteries available:

1.Flooded Lead Acid Batteries

These are the most common and traditional batteries, which require regular maintenance, including filling with water and cleaning. They are still widely used but are being replaced by other options.

2.AGM Lead Acid Batteries

These batteries are similar to flooded lead acid batteries but come at a higher cost without providing significant benefits in terms of power output or charge time.

3.Gel Lead Acid Batteries

Another type of lead acid battery, gel batteries also come at a higher cost but do not offer substantial advantages over flooded lead acid batteries.

4.Lithium-Ion Golf Cart Batteries

The most significant growth in recent years has been in the use of lithium-ion batteries for golf carts. Unlike the lithium batteries used in small devices, golf cart lithium batteries are stable and safe, specifically designed for deep-cycle applications.

They offer several advantages over lead acid batteries:

• Longevity: Lithium-ion batteries can last three to five times longer than lead-acid batteries, providing up to 4,000 charge cycles compared to 1,000 for lead-acid batteries.
• Maintenance-free: Lithium-ion batteries do not require any maintenance, such as watering or cleaning, unlike lead-acid batteries.
• Steady Power Output: The voltage of lithium-ion batteries remains consistent even as the battery is depleted, while lead-acid batteries lose power as they are used.
• Fast Recharge: Recharging lithium-ion batteries is significantly faster compared to lead-acid batteries. They can reach 80% charge in as little as one hour and achieve a full charge in 2-3 hours.
• Lightweight: Lithium-ion batteries weigh only about one-fourth of the weight of lead-acid batteries. This reduces the overall weight of the golf cart, making it more efficient and easier to maneuver.
• Environmental Impact: Lithium-ion batteries produce significantly less harmful waste compared to lead-acid batteries, with a reduction of up to 95% in waste production.

Overall, while flooded lead-acid batteries are still widely used, lithium-ion batteries offer longer lifespan, faster recharge times, lower weight, and reduced environmental impact, making them an increasingly popular choice for golf cart owners.

FAQS about Golf Cart Batteries

1.Can I use regular car batteries to replace my golf cart batteries?

You can but it’s not recommended. Golf cart batteries are designed to provide deep-cycle power, meaning they can handle repeated deep discharges and recharges, which is necessary for the continuous use of golf carts. Regular car batteries, on the other hand, are designed for starting engines and providing short bursts of power. They are not designed to handle the constant cycling and deep discharges that golf cart batteries require. Using regular car batteries in a golf cart may lead to poor performance and significantly reduced battery lifespan. It is best to use batteries specifically designed for golf carts.

2.Can I Use Car Batteries to Jump Starting My Golf Cart?

Jump starting a golf cart using car batteries is highly discouraged as it can potentially damage the deep cycle lead-acid batteries in the golf cart. This practice is not recommended.

Are there any warning signs or potential problems to be aware of with golf cart batteries?

It's important to be aware of potential issues with golf cart batteries, one of which is battery corrosion. Since golf cart batteries contain a mixture of acid and water, there is a possibility for a white, crusty film to develop on the battery's surface and contacts. This corrosion should be meticulously cleaned to prevent any shorts in the batteries, resulting in a loss of power for the golf cart. Therefore, it is crucial to keep an eye out for any signs of battery corrosion and address it promptly.

Upgrading your golf cart battery to lithium can solve this problem.
