One of the most frequently asked questions we hear at our stores is, “how long do golf cart batteries last?” Are you too curious about the longevity of your golf cart batteries? Understanding the lifespan of these essential power sources is crucial for every golf cart owner. If you have a Lithium-Ion Battery, you can expect a life span of at least eight years. Let’s explore the factors influencing their durability and discover valuable tips to extend their life.

Battery Type

The type of battery installed significantly impacts its lifespan. Typically, lead-acid batteries, including flooded, gel, and AGM (Absorbent Glass Mat) variants, are commonly used in golf carts. Based on their maintenance and usage, these golf cart batteries can last anywhere between 2 to 5 years.

One of the best golf cart batteries, the Trojan GC2 48V Lithium-Ion Battery, has an expected life of at least eight years or 4,000 cycles to 70% depth of discharge. Expected life is per manufacturer guidelines.

If you haven’t already, upgrading to a lithium-ion battery is a great investment. They are lighter, offer faster charging, and have a longer life. 

Charging Habits

Proper charging is vital for battery health, and charging habits need to go hand in hand with your golf cart usage patterns. For example, using the golf cart for a long time without recharging enough can cause the batteries to wear out faster. The repeated discharge and insufficient recharge cycles strain the battery cells, potentially shortening their lifespan.

Moreover, consistent short trips, though seemingly less demanding, can pose a different challenge. Brief outings might not allow the batteries to reach their full recharge potential. Incomplete recharging cycles can gradually degrade the batteries’ overall capacity and efficiency over time, impacting their long-term durability.

Overall, following manufacturer recommendations for charging cycles is a best practice, but in addition, here are two rules-of-thumb for proper battery charging:

Avoid Overcharging: Excessive charging can be detrimental to battery health. Overcharging happens when batteries get too much charge, causing high temperatures and chemical reactions that damage the battery’s insides. Following the manufacturer’s recommended charging cycles helps prevent overcharging and preserves battery life.

Prevent Undercharging: Don’t undercharge or leave batteries discharged for too long, as it can harm their lifespan. When batteries are not used for a long time, they can get sulfation. This means sulfur crystals form on the battery plates, making them less efficient and reducing their capacity. Regularly maintaining a charged state helps mitigate sulfation and ensures better battery health.

Maintenance Practices

Regular battery maintenance plays a crucial role in prolonging battery life. Keep the batteries clean, inspect for corrosion, and ensure proper water levels (for flooded batteries). Tighten connections and routinely check for any signs of wear or damage.

Environmental Factors

Extreme temperatures, both hot and cold, can affect battery performance. Storing carts in excessively hot or cold environments can reduce the battery’s efficiency and lifespan. Proper storage and climate control can help mitigate these effects.

Hot Environments: High temperatures accelerate chemical reactions within the battery, leading to increased internal degradation. This can result in faster electrolyte evaporation, causing reduced water levels in flooded batteries and accelerated corrosion of internal components.

Cold Environments: Extremely cold temperatures can impede the chemical reactions necessary for optimal battery function. Cold weather causes a decrease in battery efficiency, slowing down the chemical processes needed to produce energy.

Pro Tip: Store golf carts in environments with moderate temperatures whenever possible. Enclosed spaces, such as garages or storage areas, can shield the carts from extreme weather conditions.

Upkeep and Replacement

As batteries age, their efficiency diminishes. Keep an eye on performance indicators such as decreased range or slower acceleration. 

Indicators of Declining Battery Performance:

Reduced Range: Noticeably decreased mileage or range per charge is a common indicator of aging batteries. If your cart covers shorter distances on a full charge compared to its previous performance, it might signal declining battery health.

Slower Acceleration: As batteries age, they might struggle to deliver sufficient power for quick acceleration. If you notice a sluggish response or a gradual decline in the cart’s acceleration, it could be a sign of deteriorating battery efficiency.

Longer Charging Times: Batteries nearing the end of their lifespan might require extended charging times to reach full capacity. If charging times significantly increase, it could indicate reduced battery efficiency.

When these signs become apparent, you might be able to rejuvenate your golf cart battery on your own. In case none of the techniques prove helpful, consider replacing the batteries to maintain optimal cart performance.

How Long Do Golf Cart Batteries Last? – It Depends

Golf cart battery life depends on the type, usage, charging, maintenance, and environment in which the golf cart is stored. Fortunately, it is within your power to extend the battery’s life and preserve its value to avoid costly repairs or replacements. To make your golf cart batteries last longer, follow maintenance routines, manufacturer guidelines, and pay attention to how you charge them. Remember, a well-cared-for battery ensures a smoother and more enjoyable ride!
