How Long do Golf Cart Batteries Last?

At Isle Golf Cars, we get this question all the time. Unfortunately, it is one of the hardest to answer. The correct answer is: It all depends on how you take care of them. Why is this? Well, deep cycle battery packs require some basic maintenance which includes maintaining the correct electrolyte (water) levels while ensuring the battery pack is fully charged and never left in a discharged state (plugging it in after each use or a round of golf).

Besides maintenance practices, how often you use your golf cart will also significantly impact its battery life. The battery packs on golf course fleets are typically used much more than those on privately owned carts. Fleet carts might cover 2-3 rounds of golf each day during peak seasons, while private carts tend to be used 3-5 times per week (which could be more depending on the number of users). That said, properly maintained batteries in fleet carts usually last around 4-6 years, while private owners can expect around 6-10 years from their batteries.

Other important factors include the various options installed on the cart that may increase battery consumption. Features like headlights, taillights, or an enhanced speed code can all affect the overall range and performance of the deep cycle batteries.

If you live in or near a golf community and frequently drive to the course, this also impacts your battery pack. For example, driving to the golf course, playing a round, and then returning home can be comparable to 2-3 rounds of golf for a fleet cart, which may lead to a shorter battery lifespan for these owners.

To check the age of your Trojan deep cycle battery, simply look for the two digits on the negative post. The letter signifies the month of production (A=Jan, B=Feb, C=Mar...) and the number indicates the year (9=2019, 0=2020, 1=2021, etc.). For instance, a battery stamped A9 was manufactured in January of 2019.

While gas models are available, most golf carts are powered by batteries, specifically lead-acid batteries with 6, 8, or 12-volt deep cycles.

Unlike car batteries, golf cart batteries do not automatically recharge during use. Therefore, they experience greater wear and tear from continuous charging and discharging, which may lead to a shorter lifespan.

What is the Average Life Expectancy of Golf Cart Batteries?

This is a complex question, as several factors influence a golf cart battery's lifespan. They can last anywhere from several months to 5-7 years under suitable conditions. However, if left idle in high temperatures for extended periods (like a hot garage in summer) or unused for months, their lifespan can be significantly affected.

Replacing a dead battery is not only frustrating but also costly and time-consuming. That's why proper care and maintenance are crucial for ensuring the longevity of your golf cart battery.

How to Make Golf Cart Batteries Last Longer - Tips and Tricks

1. Maintain Fluid Levels

Your battery needs water—specifically distilled water. When fluid levels drop below the plates, or if the fluid is too high, it can lead to battery damage or acid leaks, both unfavorable outcomes.

2. Use the Right Charger

Always adhere to the manufacturer’s recommendations regarding which charger is best suited for your battery. We suggest using a 3-phase charger for optimal longevity and efficiency. After each use, charge your battery back to its full capacity.

3. Trickle Charge During Long Periods of Storage

Whether it's offseason or you don't plan on using your cart for a while, neglecting your battery can drastically reduce its lifespan. A trickle charge function on your charger can help maintain the battery’s power level during periods of inactivity.

4. Reduce the Risk of Corrosion

While your battery is built to last, it is not immune to corrosion caused by various elements. Ensure that metal connections and posts are kept dry and cover your battery in a temperature-controlled space whenever possible.

5. Don't Skimp on Quality

A battery is one component where you shouldn't cut corners. Cheaper batteries often have shorter lifespans. Opt for a mid to high-priced model with a solid warranty; with proper maintenance, these batteries can last 7-10 years. Investing now can save you from future frustrations.

Final Thoughts on How Long Golf Cart Batteries Last

Batteries are vital for your cart, powering it along the course and up hills. With proper care, your battery is an investment that can last for years.

Make sure to follow your manufacturer’s guidelines, recharge after every use, and trickle charge during storage periods to keep your cart running smoothly for many years to come.
