Flooded Lead-Acid (FLA)

Flooded lead-acid batteries are the most common type in traditional golf carts. They are affordable and widely available, but they require regular maintenance, including checking water levels and cleaning terminals. With proper care, a quality flooded lead-acid battery typically lasts 3 to 6 years. Without maintenance, that lifespan can drop quickly.

AGM Lead-Acid

Absorbent Glass Mat (AGM) batteries are sealed lead-acid batteries that require less maintenance than flooded types. They have slightly better vibration resistance and no need for watering. A good AGM battery in a golf cart can last 4 to 7 years when properly charged and stored. However, they still share some limitations of lead-acid technology, such as lower cycle life compared to lithium.

Lithium-Ion (LiFePO₄)

Lithium golf cart batteries are rapidly gaining popularity because they offer 8 to 12 years of service life, often delivering 3,000 to 5,000 charge cycles. Unlike lead-acid, lithium batteries can be discharged much deeper without damage, have a longer lifespan, and require almost no maintenance. While the upfront cost is higher, their long life and performance make them a cost-effective choice in the long run.

2. Factors That Affect Battery Life

Even the best battery won’t last if it’s poorly treated. Here are the main factors that influence how long your golf cart battery will last:

• Charging Habits – Batteries last longer when charged after each use rather than being left partially discharged.
• Depth of Discharge (DoD) – Avoid draining lead-acid batteries below 50% capacity; lithium batteries can handle 80–100% DoD, but shallow cycles still extend their life.
• Maintenance – Flooded lead-acid batteries need regular watering and terminal cleaning. Neglect can shorten life dramatically.
• Storage Conditions – Store in a cool, dry place. Excessive heat accelerates chemical degradation.
• Usage Patterns – Frequent heavy loads, hilly terrain, or high-speed use will put more strain on batteries.

3. How to Make Golf Cart Batteries Last Longer

1. Charge Properly – Use a smart charger compatible with your battery type to avoid overcharging or undercharging.
2. Avoid Full Drains – Lead-acid batteries especially dislike being fully drained; charge before they drop below 50%.
3. Maintain Lead-Acid Batteries – Check water levels monthly, and only top up with distilled water after charging.
4. Keep Batteries Clean – Corrosion on terminals increases resistance and reduces performance.
5. Follow Manufacturer Guidelines – Each battery model may have specific care recommendations.

4. Lead-Acid vs. Lithium: Which Lasts Longer?

If your priority is longevity, lithium batteries clearly outperform lead-acid. A lithium golf cart battery may last twice as long as a lead-acid battery, while delivering consistent power output until nearly empty. Additionally, lithium batteries are lighter, charge faster, and require virtually no maintenance—making them ideal for both recreational and commercial carts.

For golf courses, resorts, and fleet operators, the reduced downtime and maintenance costs can make lithium an even more attractive investment.
