How Many Batteries Does A Golf Cart Take? Get Answers!

Most golf carts use 4, 6, or 8 batteries. The exact number depends on the golf cart’s total power system, usually 36-volt, 48-volt, or 72-volt. For example, a 36-volt golf cart might use six 6-volt batteries, and a 48-volt cart might use six 8-volt batteries or four 12-volt batteries. This guide will help you learn all about your golf cart’s power needs.

Why The Number of Batteries Matters

The number of batteries in a golf cart directly affects its power and how far it can go. More batteries, or batteries with higher individual voltage, mean more overall power. This power gives your cart speed and range.

Think of it this way:
* More power helps your cart go up hills easily.
* More power means it can carry more weight.
* More power helps it go faster.
* More range means you can drive it for longer before needing to charge it.

Knowing how many batteries your cart needs helps you keep it running well. It also helps you buy the right parts when it’s time for new ones.

Making Sense of Golf Cart Battery Voltage

Every golf cart runs on a certain total voltage. This total voltage comes from adding up the voltage of each battery in the cart. Batteries are connected in a special way called “series.” When batteries are in series, their voltages add up.

For example:
* If you have six 6-volt batteries, they add up to 36 volts (6 batteries x 6 volts/battery = 36 volts).
* If you have six 8-volt batteries, they add up to 48 volts (6 batteries x 8 volts/battery = 48 volts).
* If you have four 12-volt batteries, they also add up to 48 volts (4 batteries x 12 volts/battery = 48 volts).

This total golf cart battery voltage tells you how powerful your cart is. It is important to know your cart’s total voltage. This helps you get the right batteries for golf cart battery replacement when needed.

Different Battery Voltages

Individual golf cart batteries come in a few common voltages:

6 volt golf cart batteries: These are very common. They are used in many 36-volt and 48-volt systems.
8 volt golf cart batteries: These are also popular, especially in 48-volt systems.
12 volt golf cart batteries: You might find these in some 36-volt or 48-volt carts. They are less common for golf carts but still used.

Your cart will use one type of these batteries. You will have multiple of them to reach the total system voltage.

Common Golf Cart Battery Setups

Most golf carts use either a 36-volt or 48-volt system. Some newer, more powerful carts, or those used in tougher conditions, might use a 72-volt system.

36 Volt Golf Cart Batteries

A 36-volt golf cart is often a good choice for flat courses or basic neighborhood driving. They are usually less expensive than 48-volt carts.

To reach 36 volts, golf carts typically use:
* Six 6-volt golf cart batteries. This is the most common setup for 36 volt golf cart batteries.
* Example: EZ-GO TXT models often use this setup.

48 Volt Golf Cart Batteries

48 volt golf cart batteries are becoming the most popular choice. They offer more power and range than 36-volt carts. This makes them better for hilly areas or longer trips.

To reach 48 volts, golf carts can use different battery setups:
* Eight 6-volt golf cart batteries. This is a very common setup.
* Example: Many Club Car and Yamaha models use this.
* Six 8-volt golf cart batteries. This setup is also very common.
* Example: Many newer Club Car and EZ-GO models use this.
* Four 12-volt golf cart batteries. This setup is less common but still used.
* Example: Some older or custom carts might use this.

72 Volt Golf Cart Batteries

Some carts, especially powerful models or those for specific tasks, use 72 volts. These carts have even more speed and power.

To reach 72 volts, a cart might use:
* Twelve 6-volt golf cart batteries.
* Nine 8-volt golf cart batteries.
* Six 12-volt golf cart batteries.

These higher voltage systems are often found in new, high-performance golf carts. They also appear in utility vehicles.

How To Find Your Golf Cart’s Voltage

It is easy to find out your golf cart’s total voltage and how many batteries it uses.

Open the battery compartment: This is usually under the seat.
Count the batteries: See how many individual battery units are there.
Check the voltage on each battery: Look for a label on each battery. It will say “6V,” “8V,” or “12V.”
Multiply: Multiply the number of batteries by the voltage of one battery.
- Example: If you see six batteries, and each says “6V,” then you have a 36-volt golf cart (6 x 6 = 36).
- Example: If you see eight batteries, and each says “6V,” then you have a 48-volt golf cart (8 x 6 = 48).
- Example: If you see six batteries, and each says “8V,” then you have a 48-volt golf cart (6 x 8 = 48).

Different Golf Cart Battery Types

When we talk about golf cart battery types, we mostly mean two main kinds: lead-acid batteries and lithium-ion batteries. Each type has its own pros and cons.

Lead-Acid Batteries

Lead-acid batteries have been the standard for golf carts for a long time. They are known as deep cycle golf cart batteries. This means they are made to give power over a long time. They can be drained deeply and then recharged many times. This is different from car batteries, which give a quick burst of power to start an engine.

There are a few types of lead-acid batteries:

Flooded Lead-Acid (Wet Cell):
- How they work: These batteries have liquid inside them (water and acid). They need regular care.
- Pros:
  - They cost less to buy.
  - They have a long history of use.
- Cons:
  - They need regular checks and refills of distilled water.
  - They can let out gases. This means you need good airflow where you charge them.
  - They are heavy.
  - They charge slower.
  - Their power can drop as they lose charge.
- Best for: People who want to save money upfront and don’t mind doing some upkeep.
Absorbed Glass Mat (AGM):
- How they work: The acid is held in special glass mats, not as a liquid.
- Pros:
  - They do not need water refills.
  - They do not let out much gas.
  - They can be placed in different positions.
  - They are less likely to leak.
- Cons:
  - They cost more than flooded batteries.
  - They can be damaged if you drain them too much.
- Best for: People who want less maintenance but are willing to pay a bit more.
Gel Cell:
- How they work: The acid is mixed with a gel.
- Pros:
  - They do not need water refills.
  - They do not let out gas.
  - They are good in extreme heat.
- Cons:
  - They cost more than AGM batteries.
  - They charge slowly.
  - They can be damaged if you overcharge them.
- Best for: Very specific uses where high heat or no venting is a must. Less common for golf carts than flooded or AGM.

Lithium-Ion Batteries

Lithium-ion batteries are a newer option for golf carts. They are becoming more popular. They work very differently from lead-acid batteries.

How they work: They use lithium compounds to store and release energy.
Pros:
- Lightweight: They weigh much less than lead-acid batteries. This makes the cart lighter and more efficient.
- Longer Life: They can last 2-3 times longer than lead-acid batteries.
- No Maintenance: They do not need water refills or cleaning.
- Faster Charging: They charge much quicker.
- Consistent Power: Their power does not drop as they lose charge. You get full power until they are almost empty.
- Safe: Modern lithium golf cart batteries have built-in safety systems.
Cons:
- Higher Initial Cost: They cost more to buy at first.
- Specific Chargers: They often need a special charger.
Best for: People who want top performance, no maintenance, and a longer lifespan, and are ready to pay more upfront. The higher cost often pays off over time.

Here is a quick comparison of common deep cycle golf cart batteries:

Feature	Flooded Lead-Acid	Lithium-Ion
Initial Cost	Low	High
Lifespan (Cycles)	500-1000	2000-5000+
Maintenance	Regular water refills, cleaning	None
Weight	Very Heavy	Much Lighter
Charging Time	8-10 hours	2-4 hours
Power Output	Drops as charge lowers	Consistent until nearly empty
Energy Efficiency	~80%	~99%
Installation	Multiple heavy units	Fewer, lighter units, often drop-in
Safety Concerns	Gas release, acid spills (rare)	Very safe with built-in protections

Golf Cart Battery Arrangement: Connecting Them Right

When you have multiple batteries in a golf cart, they must be connected correctly. This connection is called golf cart battery configuration. For golf carts, batteries are almost always wired in “series.”

How Series Wiring Works

When batteries are wired in series:
* The positive (+) terminal of one battery connects to the negative (-) terminal of the next battery.
* You use special cables to link them up.
* The total voltage adds up. For example, six 6-volt batteries make 36 volts.

This setup helps the cart get the total voltage it needs to run. It’s like a chain. If one link is weak, the whole chain is weak. This is why all batteries in your cart should be the same age and type.

Why All Batteries Must Match

It is very important that all batteries in your golf cart are:
* The same voltage: For example, all 6V or all 8V.
* The same type: All flooded lead-acid, or all lithium. Do not mix them.
* The same age: Using old and new batteries together can harm the new ones. The older batteries will weaken the new ones.

If you are doing a golf cart battery replacement, change all of them at once. Do not just change one or two.

Taking Care of Your Golf Cart Batteries

Proper care makes your batteries last longer. This applies to both lead-acid and lithium types, though the care steps differ.

Care for Lead-Acid Batteries

Lead-acid batteries need more attention than lithium ones.

Check Water Levels Often:
- This is key for flooded lead-acid batteries.
- Check levels every 2-4 weeks, more often in hot weather.
- The water should cover the plates inside the battery.
- Use only distilled water. Tap water has minerals that can damage batteries.
- Fill cells after charging, unless plates are exposed before charging. Do not overfill.
Keep Them Clean:
- Clean the tops of batteries. Acid can build up.
- Use a mix of baking soda and water to clean away corrosion.
- Dry the tops well after cleaning.
Check Connections:
- Make sure battery cables are tight. Loose cables can cause problems.
- Check for corrosion on terminals. Clean it off if you see any.
Charge Them Right:
- Always charge after each use, even short trips.
- Avoid letting batteries run fully flat. This can harm them.
- Use a charger designed for your battery type and voltage.
- Do not overcharge. Modern chargers usually stop when full.
Store Them Well in Winter:
- If you store your cart for a long time, charge the batteries fully first.
- Store them in a cool, dry place.
- Check the charge every month and top it up if needed.

Care for Lithium-Ion Batteries

Lithium-ion batteries are much easier to care for.

No Water Needed: They are sealed units. You never add water.
No Cleaning: They don’t have acid spills or corrosion issues.
Charge as Needed: Charge them when you want. You don’t have to charge after every use if you don’t want to.
Use The Right Charger: Always use the charger made for your specific lithium battery.
Store Them: If storing for a long time, charge them to about 50-70%. Store in a cool, dry place.

When To Consider Golf Cart Battery Replacement

Even with good care, batteries don’t last forever. How long they last depends on:
* Battery type
* How often you use the cart
* How well you care for them
* The weather

Most lead-acid golf cart batteries last about 3 to 6 years. Lithium-ion batteries can last 8 to 10 years or more.

Signs You Need New Batteries

Watch for these signs that your batteries are getting old:
* Less Power: Your cart feels slower, especially uphill.
* Shorter Range: Your cart does not go as far on a full charge.
* Longer Charging Times: It takes much longer to charge fully.
* Quick Power Drop: The battery meter drops quickly after charging.
* Bulging Batteries: The sides of your batteries look swollen. This is a serious sign.
* Leaking Batteries: You see acid or liquid around the battery tops.
* Old Age: If your batteries are over 5-6 years old, they are likely nearing the end of their life.

When you notice these signs, it’s time to plan for golf cart battery replacement. Replacing them all at once will give your cart its full power back.

Getting New Golf Cart Batteries

When you replace your batteries, you have choices to make.

Stick With What You Have

If you were happy with your old batteries and don’t want to spend too much, replace them with the same kind.
* Make sure the voltage (6V, 8V, 12V) and type (flooded, AGM) are the same.
* Buy all new batteries at once. Do not mix old and new.

Think About Upgrading to Lithium

If you want better performance, less maintenance, and a longer battery life, consider switching to lithium-ion batteries.

Things to think about when upgrading:
* Cost: Lithium batteries cost more at first. But they last longer, so they can save money over time.
* Charger: You will need a new charger made for lithium batteries.
* Installation: Some lithium batteries are “drop-in” replacements, meaning they fit easily. Others might need small changes.
* Weight Savings: Enjoy a lighter cart. This can make it faster and go further.
* No Maintenance: Forget about watering or cleaning.

Steps for Golf Cart Battery Replacement:

Safety First: Turn off the cart. Take off the key. Wear gloves and eye protection.
Disconnect: Disconnect the main negative cable first, then the main positive cable. Take photos of how the cables are connected. This helps you hook up the new ones correctly.
Remove Old Batteries: Carefully lift out the old, heavy batteries.
Clean Tray: Clean the battery tray. Remove any dirt or corrosion.
Install New Batteries: Place the new batteries into the tray.
Connect Cables: Connect the cables in the reverse order of how you took them off. Connect the individual battery cables first (positive to negative for series connections). Then connect the main positive cable, then the main negative cable last. Double-check your golf cart battery configuration.
Charge: Charge the new batteries fully before using the cart.

If you are not sure how to do this, ask a pro. It is important to do it right for safety and good performance.
