Choosing the right battery for your golf cart is crucial for performance, longevity, and overall cost-effectiveness. Golf carts primarily run on either lead-acid (electric) batteries or lithium-ion batteries, and each has its own advantages and disadvantages. If you're looking at which battery to choose for your golf cart understanding the differences can help you make the best decision.


1. Understanding the Basics

  • Lead-Acid Batteries: These have been the standard power source for golf carts for decades. They are affordable but require regular maintenance and have a shorter lifespan.

  • Lithium-Ion Batteries: A more recent innovation in golf carts, lithium batteries offer better performance, efficiency, and longevity with zero maintenance.

The batteries on the top are lead acid and the battery on the bottom is lithium.

2. Key Differences Between Lithium and Lead-Acid Batteries


A. Weight & Efficiency

  • Lead-acid batteries are heavier, which can reduce a golf cart’s speed and efficiency.

  • Lithium batteries are lightweight, leading to better acceleration, smoother rides, and improved energy efficiency.

B. Charging Time & Maintenance

  • Lead-acid batteries take 6-8 hours to charge and require regular maintenance, such as watering and terminal cleaning.

  • Lithium batteries charge in 2-4 hours, require zero maintenance, and handle partial charging without damaging the battery.

C. Longevity & Lifespan

  • Lead-acid batteries typically last 3-5 years with proper maintenance.

  • Lithium batteries last 8-10+ years, making them a better long-term investment.

D. Performance, Speed, & Mileage

  • Lead-acid batteries experience voltage drop as they discharge, causing carts to slow down over time.

  • Lithium batteries provide consistent power output, meaning the cart maintains peak performance throughout the charge cycle.

  • Lithium-powered carts generally have a higher top speed, often reaching 2-5 mph faster than their lead-acid counterparts.

  • A fully charged lithium battery can offer 40-60 miles per charge, whereas lead-acid batteries typically provide 15-30 miles per charge, depending on terrain and load.

E. Cost & Value

  • Lead-acid batteries are cheaper upfront but have higher long-term costs due to frequent replacements and maintenance.

  • Lithium batteries have a higher initial cost but offer greater value over time due to their longevity and efficiency.


3. EZGO’s Samsung Lithium Battery: The Best Lithium Option?

EZGO golf carts come equipped with Samsung SDI lithium batteries, which are considered among the best in the industry. Here’s why they stand out:
