As an important transportation tool for golf courses, resorts, communities, and industrial areas, the power system of golf carts directly affects the user experience and operating costs. At present, golf cart batteries are mainly divided into lead-acid batteries and lithium batteries. There are significant differences between these two types of batteries in terms of cost, range, lifespan, maintenance, and environmental protection. The following content analyzes the differences between two types of batteries from multiple perspectives, helping industry practitioners make wiser choices.
Technology and Structure
Lead Acid Battery Golf Cart
Working Principle: Lead-acid batteries store and release electrical energy through the chemical reaction of lead (Pb) and lead dioxide (PbO₂) with sulfuric acid (H₂SO₄) electrolyte. During discharge, the lead and lead dioxide are converted into lead sulfate (PbSO₄), and this process is reversed during charging.
Common Types: Rich liquid lead-acid batteries and sealed lead-acid batteries
Battery Composition: A 36V, 48V, or 72V system is composed of 6V or 8V single cells connected in series, which is relatively heavy.
Lithium Battery Golf Cart
Working Principle: Lithium batteries rely on the movement of lithium ions (Li⁺) between the positive and negative electrodes (such as lithium iron phosphate LiFePO₄ or ternary lithium NMC) to store energy, and they have higher energy density.
Common Types: Lithium Iron Phosphate and Ternary Lithium Batteries
Battery Components: Utilizing a lightweight modular design, this battery is 30-50% lighter than lead-acid batteries.
Conclusion: Lithium batteries are superior to lead-acid batteries in energy density, weight, and efficiency. However, lead-acid battery technology is more mature and with lower initial costs.

Temperature Adaptability
Lead-Acid Batteries
- Low Temperatures (<0°C): Capacity drops by 30-50%, and charging may become impossible.
- High Temperatures (>40°C): Accelerates sulfation and shortens battery life.
Lithium Battery
- Low Temperature: Capacity drops by 10-20%
- High temperature: With small impact, but extreme high temperatures should be avoided.
Conclusion: Lithium batteries have significantly longer lifespan and are more suitable for extreme climate areas.

Conclusion
Lead-acid battery golf carts, due to their low cost and mature technology, remain a practical choice for budget-conscious users. However, they have shortcomings in battery life, maintenance, and lifespan. While lithium battery golf carts have a higher initial cost, they offer significant advantages in performance, long-term costs, and user experience. Their cost-effectiveness is rapidly improving, especially with declining lithium prices and mature recycling technologies.
From the perspective of industry trends, lithium batteries will become the mainstream development direction of electric golf carts. For individual users with limited budgets, lead-acid battery golf carts are a good option. Conversely, if the purchase budget is sufficient, lithium battery golf carts are more cost-effective.
