If you’re in search of the perfect round, start with a battery built to go the distance. In this guide, we’ll take a closer look at golf cart batteries — what they are, how to choose the right ones, and how to care for them properly for a full season of on-course fun.
What Are Golf Cart Batteries?
Golf cart batteries (also referred to as low-speed EV batteries) are specially designed to power small, lightweight electric vehicles — like golf carts.
While these batteries do provide power for electric vehicles, they aren’t interchangeable with EV batteries found in an electric car like a Tesla or Prius; EV Automotive batteries are built for high-performance and high-voltage applications. Those designed for golf carts and lightweight EV applications provide sustained power over extended periods. Key characteristics include:
- Deep-cycle design for consistent performance. Golf cart batteries deliver steady power over long periods, making them ideal for continuous low-speed applications.
- Available in multiple chemistries. Flooded Lead Acid batteries remain popular and cost-effective. AGM and Lithium Ion versions offer a maintenance-free option, longer life cycle and faster charging.
- Configured for 36V or 48V systems. Golf cart batteries are commonly installed in a series to meet the cart’s voltage requirements.
Types of Golf Cart Batteries: Chemistry
Golf cart batteries come in a variety of chemical compositions, each offering advantages depending on performance needs, maintenance preferences and budget. The most common golf cart batteries are flooded Lead Acid (FLA), AGM and Lithium.
Flooded Lead Acid (FLA). While they may require maintenance, FLA batteries are readily available and typically the least expensive of the golf cart battery options. They can also spill or leak acid and are somewhat less efficient than AGM or lithium batteries.
Absorbed Glass Mat (AGM). A member of the Lead Acid battery family, AGMs are sealed, maintenance-free and resistant to vibration. Their slightly higher energy density means they can hold more energy in a smaller space, making them ideal for compact battery compartments or higher-demand golf cart applications. They are more expensive than FLAs but have a longer lifespan.
Lithium-ion (Li-Ion). Lead batteries are less expensive upfront, but nothing can beat lithium when it comes to longevity. Lithium golf cart batteries can last through 5,000 charging cycles — more than 20 times that of a standard lead golf cart battery. They are also lightweight, making them a popular choice for small EVs.

Types of Golf Cart Batteries: Voltage & Configuration
Golf cart batteries come in 6-volt, 8-volt and 12-volt capacities, and are sold in groups by voltage (24, 36 or 48). A cart’s voltage and capacity requirements vary depending on the cart manufacturer or the aftermarket installations. There are carts that can support 36–, 42– or 72–volt packs, but the average golf cart requires 48 volts of battery power to operate.
For example, if your cart requires 48V, you can typically purchase a pack of eight 6V batteries or four 12V batteries. While both configurations give you the required 48 volts, there are some slight differences in how they power your cart.
The Lithium All-In-One Battery Pack
While the majority of golf cart batteries are sold in packs composed of individual cells, the Lithium all-in-one battery packs deliver a simplified, single-unit solution. Designed to replace multi-battery configurations, the pack comes integrated with 24 or 48 volts. The compact system minimizes maintenance and offers consistent, high-efficiency performance.
How to Choose the Best Golf Cart Battery: AGM, Lithium and More
The first consideration when it comes to choosing a golf cart battery is the requirements of your cart. Consult your manual to understand the voltage and amperage specifications. Always match the battery voltage to your cart’s system — under or over-volting can damage components and void warranties.
Beyond the base requirements, your usage patterns can help you choose the best battery for golf carts.
Ask yourself:
How often and how far do you drive?
Frequent (daily) use or longer range is best suited to 6V batteries or Lithium. Both of these have higher capacity and longer runtimes.
What is your maintenance preference?
If you’re looking for maintenance-free, choose Lithium or AGM. FLA will require some checking and topping off.
What’s your budget?
FLA is the most affordable option upfront, while Lithium costs significantly more but offers a longer lifespan. AGMs sit between cost and longevity.
What are your driving conditions like?
For extreme heat or rugged terrain, AGM or lithium batteries may perform best because they are vibration resistant.
How to Maintain Your Golf Cart Batteries
Even maintenance-free batteries require some care to ensure the longest possible life. Here are some tips for making sure your batteries are in top shape during the season and in the off-season.
Before Golf Season
As you’re bringing your cart or carts out of storage and readying them for the golf season ahead, make sure your batteries are ready to go, too.
- Inspect batteries for signs of wear. This can include bulges or cracks in the cases. If you spot any external damage, the battery should not be used.
- If there is noticeable dirt or corrosion, clean it with a wire brush and baking soda solution (for lead batteries only).
- Make sure all terminal connections and vent caps are secure.
- Test the battery’s voltage with a multimeter to ensure it's holding a full charge.
- If your battery is reaching the end of its predicted lifespan, consider replacing it.
During Golf Season
For rental carts that make multiple rounds daily (or frequently used personal carts):
- Charge golf cart batteries fully after each use. Use a battery charger that matches your battery pack, and let it complete a full charge cycle according to the manufacturer's instructions.
- Never run your battery down to zero charge, as this can shorten its lifespan.
- Visually inspect batteries for signs of damage or signs of corrosion and clean them as needed.
- Store the cart out of direct sunlight and heat to prolong battery life.
- Don’t overload your cart. The average golf cart is designed to tow between 500 and 1,200 pounds, depending on the number of seats. Exceeding this limit will put stress on the cart and the battery.
At the End of the Season
When it’s time to store your golf cart for the off-season, it’s important not to overlook battery care.
- Remove the batteries from the carts, and clean the terminals and cable connections to prevent corrosion.
- Store batteries in a cool, dry location and cover them to protect against dust and moisture. (Avoid areas with freezing temperatures or heat sources such as space heaters or radiators.)
- To preserve battery life, recharge them every three months during storage. Consider using a battery maintainer with a storage mode feature that automatically keeps batteries charged and ready for next season.
Replacing Your Golf Cart Batteries
When it’s time to swap out your golf cart battery, remember to check the manufacturer specifications for the right voltage and amperage. You can search for replacement golf cart batteries at ContinentalBattery.com or visit a retail location near you.
Don’t Forget to Recycle!
Lead Acid batteries are one of the most recycled consumer items on the market. You can drop off your dead batteries at any Continental Battery Systems retailer to ensure they are properly recycled and do not end up in the landfill.
Lithium batteries are also recyclable and require specialized processing. Learn more about how to handle and recycle lithium batteries.
