What is the Usual Lifespan of Golf Cart Batteries?-Acoucou Batteries B

Golf carts have become increasingly popular for transportation on golf courses, residential communities, and even as an eco-friendly means of transportation in urban areas. One crucial component that determines the performance and longevity of a golf cart is its battery. It determines the driving range and high output of the golf cart. Each battery has a different lifespan, depending on its chemical type and configuration.

Golf Cart Electric System

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, there are many factors influencing the load consumption of the engine, such as the type of terrain and tires used, motor efficiency, and weight carried. It should be noted that the current draw can increase significantly during acceleration or when navigating uphill terrain.

Battery Types

The most common rated voltages for battery packs are 6V, 8V, and 12V. Different types of battery chemistry also determine the service life of batteries. Common golf cart batteries include lead-acid batteries and lithium iron phosphate batteries.

Lead-acid batteries

It is the cheapest and most widely used in the market. Compared to other batteries, it has a lower energy density and is heavier. It has a shorter life and fewer cycles usually 200-500 times. It is generally not recommended to discharge lead-acid batteries below 50% of the battery capacity.

1. Flooded lead-acid batteries (FLA)

Flooded lead-acid batteries, also known as deep-cycle or wet-cell batteries, have been the traditional choice for golf carts. If properly maintained, the service life of FLA can reach 8 years. These batteries use a liquid electrolyte solution and are constructed with lead plates submerged in sulfuric acid. FLA batteries are known for their affordability and are suitable for standard recreational golf cart use. They require regular maintenance, including checking and adding distilled water to the cells to ensure proper electrolyte levels.

2. Sealed Lead-Acid Batteries (SLA):

Sealed lead-acid batteries, also referred to as valve-regulated lead-acid (VRLA) batteries, offer a maintenance-free alternative to FLA batteries. SLA batteries come in two variations: Absorbent Glass Mat (AGM) and Gel batteries.

• AGM Batteries

Its average lifespan of 4 to 6 years. AGM batteries use a fiberglass mat soaked in electrolyte as a separator between the lead plates. This design enables the electrolyte to be absorbed and immobilized, making AGM batteries spill-proof and vibration-resistant. AGM batteries are generally more expensive than FLA batteries but provide better reliability and longer service life. They are suitable for golf carts that experience frequent use and demand higher performance.

• Gel Batteries

Its average lifespan of 5 to 7 years. Gel batteries feature a thickened electrolyte in a gel form that is immobilized between the lead plates. This gel electrolyte provides improved resistance to vibration, deep cycling capability, and extended lifespan. Gel batteries are highly durable, maintenance-free, and can handle high-demand applications. However, they tend to be more expensive than both FLA and AGM batteries.

LiFePO4 batteries

In recent years, LiFePO4 batteries are becoming increasingly popular as golf cart batteries owing to their unique advantages.

• Long service life: The lifespan of LiFePO4 battery is usually several times that of lead-acid battery. It can generally last for 7 to 10 years of use. Acoucou LiFePO4 battery has more than 6000 cycles and a 10-year life.
• Safety: LiFePO4 batteries are the safest battery type available today. BMS can protect the battery better and make it last longer. Acoucou LiFePO4 battery has a built-in BMS that people can check the situation of batteries through Bluetooth in the APP.
• Maintenance-free: Unlike lead-acid batteries, LiFePO4 batteries do not require regular water replenishment.
• Fast charging: Acoucou 12V 100Ah LiFePO4 battery can be fully charged in 5 hours with a charger. Lead-acid battery usually needs to be charged for 6 to 8 hours.
• Small and light: LiFePO4 batteries have higher energy density and are much lighter than lead-acid batteries. Acoucou LiFePO4 12V 100Ah is 29.98 lbs nearly 1/3 of the weight of the same type of lead-acid battery.

How to Extend the Life of Golf Cart Battery

• Proper Charging: Charge the batteries after each use, and don't let them stay deeply discharged for an extended period. Do not leave the batteries on charge for an extended period once they are fully charged. Avoid running the batteries to a very low charge level. Deep discharges can shorten battery life. Use a charger specifically designed for your type of batteries (e.g., lead-acid or lithium-ion).
• Regular Maintenance: Keep the battery and its terminals clean and free of corrosion. Check the water levels in the battery regularly and top up with distilled water as needed, if you have a flooded lead-acid battery.
• Storage: If you store your golf cart for a long time, make sure to keep the battery charged and use a battery maintainer to prevent over-discharge. Secondly, try to store and operate the golf cart in moderate temperature conditions.
• Equalizing Charge (for Lead-Acid Batteries): Perform an equalizing charge periodically, as recommended by the battery manufacturer. This helps balance the individual cells in the battery.
• Weight Consideration: Excess weight can strain the batteries and reduce their lifespan.
• Proper Driving Habits: Smooth acceleration and braking can reduce strain on the battery, so try to operate the golf cart with care.
• Upgrade to LiFePO4 Batteries: If your budget is sufficient, lithium iron phosphate batteries are a good choice. They generally have a longer lifespan and are more efficient.

Golf cart batteries are a vital component that ensures the smooth operation of these versatile vehicles. The performance and lifespan of lithium iron phosphate batteries are better than lead-acid batteries, but the price is indeed higher than lead-acid batteries, so the cost of retrofitting to golf carts is also high. The important thing is the daily maintenance of the battery, and you can choose the battery you want according to your needs. By understanding the factors affecting battery lifespan and following proper maintenance practices, you can extend the durability of your golf cart batteries.
