The lifespan of a golf cart battery can vary depending on several factors, such as its usage frequency, maintenance routine, and environmental conditions. Generally, a well-maintained battery for an electric golf cart can last around four to five years. However, signs of a deteriorating battery can start earlier, such as a decrease in driving range, slower acceleration, and longer charging time. It is recommended to regularly check the battery voltage, water levels, and charging circuit to ensure optimal performance and prevent premature failure. The battery replacement process should be done when the capacity drops below 80%, as it may affect the cart’s performance and pose safety hazards. Ultimately, replacing your golf cart battery can prolong the cart’s lifespan, improve its efficiency and power, and enhance overall driving experience.
