Pros & Cons of Lead‑Acid Golf Cart Batteries

Power - by Joe Weber - updated on 7/7/2025

When it comes to powering your golf cart, lead‑acid batteries have long been a go-to choice. But are they still the best option in 2025? Let's explore the advantages and drawbacks, particularly in the context of golf cart use.

What Are Lead‑Acid Batteries?

Lead-acid batteries are one of the most widely used rechargeable battery types, known for their durability, affordability, and ability to deliver high power over short bursts, and superior deep cycle capabilities. They've been powering vehicles and equipment for over a century, and they remain a top choice for golf carts today.

These batteries work by using lead plates submerged in a sulfuric acid electrolyte to create an electrochemical reaction. As the battery discharges and recharges, lead sulfate, lead dioxide, and sponge lead alternate across the plates, generating electricity.

There are two main types of lead-acid batteries used in golf carts:

• Flooded (or Wet Cell): These require routine maintenance, including adding distilled water and cleaning terminals. They're cost-effective and ideal for users comfortable with regular upkeep.
• Sealed Lead-Acid (SLA): This includes AGM (Absorbent Glass Mat) and gel batteries, which are spill-proof, maintenance-free, and designed to perform in a wide range of temperatures and conditions.

Thanks to their deep-cycle capabilities—meaning they can deliver a steady amount of power over a longer period—lead-acid batteries are ideal for golf carts and other electric vehicles that require long runtimes rather than quick bursts of energy.

Pros of Lead‑Acid Golf Cart Batteries

1. Low Upfront Cost

Lead‑acid batteries are affordable compared to lithium options—perfect for courses managing large fleets.

2. High Surge Power

They deliver strong bursts of current—ideal for climbing hills or pulling heavy loads. 

3. Proven Reliability

Works well across various weather and usage conditions—courses rely on its durability.

4. Widespread Availability & Recycling

Flooded and AGM types are easy to find, and lead‑acid batteries have one of the highest recycling rates of all the batteries.

Cons of Lead‑Acid Golf Cart Batteries

1. Heavy & Bulky

Lead‑acid packs are significantly heavier than lithium, impacting cart efficiency and handling.

2. Limited Deep‑Cycle Life

Flooded lead‑acid typically lasts 300–500 deep cycles; AGMs may reach 500–1,000, but still less than lithium.

3. Slow Charging

It can take 8–16 hours to fully recharge, limiting cart turnaround time.

4. Maintenance

Flooded batteries require watering and terminal cleaning. AGM/gel batteries are lower-maintenance but still require the occasional checkup to make sure the battery is in good condition. 

5. Environmental & Safety Concerns

Lead acid carries the risk of acid spills, hydrogen venting, and lead contamination. Ventilation and protective gear are essential. Lead-acid batteries must always be recycled properly.

Flooded vs AGM vs Gel: What's Best for Golf Carts?

AGM often hits the best balance for golf carts—sealed, no watering, and mid-price with decent cycle life

Golf Carts Do More Than Cruise the Course

Golf carts aren't just for the fairway anymore. Today, they're widely used in a variety of environments:

• Resorts and hotels for guest transportation
• College campuses and corporate parks for quick commutes or security staff
• Industrial facilities and warehouses for on-site mobility
• Farms and ranches for light-duty hauling
• Gated communities and retirement neighborhoods for everyday travel
• Event venues and stadiums for staff and vendor transport

For all of these uses, lead-acid batteries are a solid, cost-effective choice, especially for vehicles with predictable routes and access to charging stations. They offer the power needed for short- to mid-range trips, are easy to maintain (especially in fleet setups), and cost far less than lithium upfront. When reliability and affordability matter most, lead-acid is still a go-to solution.

Best Practices for Golf Cart Battery Care

• Charge daily—avoid deep discharge (below 50% State Of Charge).
• Equalize flooded batteries monthly to prevent stratification.
• Use the correct charger and profile for the battery type.
• Keep terminals clean and the environment ventilated.
• Cycle test VRLA batteries annually to gauge health.

Alternatives: Is Lithium Worth Considering?

While lead‑acid remains cost-effective, lithium‑iron-phosphate (LiFePO4) batteries, while harder to find, offer:

• 3–5 × more usable capacity
• 5–10 × longer lifespan (2,000+ cycles)
• 2–3 × faster charging
• ~30–50% weight reduction

Higher initial cost may be offset by lower maintenance and longer life, but budget, course size, and availability matter.

Are Lead-Acid Batteries Still Relevant?

Yes, especially for budget-conscious operations seeking reliability and proven tech. Flooded packs are inexpensive upfront; AGM adds convenience. But if low maintenance, light weight, and long lifespan are priorities—and budget allows—lithium is becoming increasingly compelling.

Frequently Asked Questions About Lead-Acid Golf Cart Batteries

Q: What type of battery is best for a golf cart?

A: It depends on your priorities. Flooded lead-acid batteries are budget-friendly but require regular maintenance. AGM offers a balance of performance and convenience, while lithium provides the longest lifespan, fastest charging, and lowest maintenance, at a higher upfront cost.

Q: What is battery equalization, and do I need to do it?

A: Battery equalization is a controlled overcharge used on flooded lead-acid golf cart batteries to prevent acid stratification. It helps mix the electrolyte, extend battery life, and maintain performance. Only flooded batteries need this—AGM and gel batteries do not. Always follow your battery or charger manufacturer's guidelines.

Q: Are golf cart batteries used in floor scrubbers?

A: Yes! Many commercial floor scrubbers and sweepers use the same deep-cycle lead-acid batteries found in golf carts. These batteries provide the sustained power needed for extended cleaning runs. If you see a battery labeled as a "golf cart battery," it often works just as well in industrial cleaning equipment—just make sure the voltage and size match your machine's requirements.

Q: How long do lead-acid golf cart batteries last?

A: On average, flooded batteries last 3–5 years with proper care. AGM and gel batteries can last slightly longer, depending on usage and charging habits.

Q: Do lead-acid golf cart batteries need maintenance?

A: Yes—flooded lead-acid batteries require regular watering, cleaning, and equalizing charges. AGM and gel batteries are maintenance-free but still need proper charging to maximize lifespan.

Q: How often should I charge my golf cart battery?

A: Charge your batteries after every use. Avoid letting them sit in a discharged state, as this can shorten their lifespan. Even if not in use, top them off every few weeks.
