When it comes to maximizing the performance and longevity of your golf cart, one crucial aspect is properly wiring a golf cart battery. Efficient wiring ensures a steady flow of power, optimal battery charging, and smooth operation of your golf cart.

In a golf course, golf carts are the silent workhorses, powered by a battery bank designed to sustain their propulsion throughout a golfing day. Golf cart battery wiring, however, differs from automobiles due to their installation in a battery bank.

In this guide, we’ll take you through a step-by-step process of wiring a golf cart battery. whether you’re replacing them or removing them for cleaning.

Maximizing Golf Cart Performance: Best Practices for Battery Wiring

For maximum efficiency, follow these guidelines:

  • Select the Correct Wire Type: Golf cart batteries require heavy-duty wire capable of handling high current flow. Choose a minimum of 6 AWG gauge wire with insulation rated for at least 105 degrees Fahrenheit.
  • Wire Connection Order: Connect the positive (+) terminal of one battery to the negative (-) terminal of the next, continuing the pattern. The final positive terminal should link to the charger’s positive terminal.
  • Use High-Quality Connectors: The connectors should be corrosion-resistant and designed for high-current applications. Crimp-on connectors are a good option, but solder connections are even better.
  • Ensure Secure Connections: Loose connections can cause arcing and heat, potentially damaging the batteries. Tighten connections with a wrench until snug.
  • Insulate Connections: Use heat-shrink tubing or electrical tape to insulate connections, preventing arcing and corrosion.
  • Disconnect Batteries Before Maintenance: This will prevent accidental sparks or short circuits.

Understanding Types of Golf Cart Batteries

Deep Cycle Batteries: These are designed to provide a steady flow of power over an extended period, making them ideal for golf carts.

Flooded Lead-Acid Batteries: The most common type used in golf carts, known for their affordability and reliability.

AGM Batteries: Absorbent Glass Mat batteries are maintenance-free and offer excellent performance.

Step-by-Step Instructions to Wire a Golf Cart Battery

  • Accessing the Battery Compartment: The first step is to open the battery compartment of your golf cart. This is usually located beneath the seat, it can be easily lifted out.
  • Disconnect Cables: Start by removing the black negative cable from the first battery in the bank, followed by the subsequent positive wire. Repeat this process for each battery in the bank, moving from forward to rear.
  • Remove Batteries: Lift out the batteries, some of which may require a wrench to remove the securing nut and washer from the bracket.
  • Installing New Batteries: Position the new batteries as per the removed ones and secure the brackets.
  • Reconnecting the Battery Cables: Reconnect the battery cables to the batteries in the bank. The main positive lead for the battery bank, coming from the frame of the cart, will connect to the positive terminal of the first battery in the bank. Then, connect a cable from the negative terminal of the first battery to the positive terminal of the subsequent battery in the bank. Continue this pattern until all batteries are connected. The last battery in the bank will have a connection from its negative terminal to the frame or golf cart controls.
  • Connect Reverse Positive Cable: This is the extra positive cable that you disconnected when removing the batteries. This cable powers the engine when the cart moves in reverse.

Golf Cart Battery Maintenance: Disconnecting Batteries

If you need to disconnect your golf cart batteries for cleaning or maintenance, follow these steps:

Here are the steps to do so:

  • Ensure Safety First: Put on your acid-resistant work gloves before starting the battery removal process.
  • Disconnect Battery Bank: Disconnect the battery bank positive lead from the positive golf cart body main power connection with a wrench.

After the positive lead is disconnected, disconnect the battery bank’s ground wire from the primary golf cart body connection.

  • Disconnecting the Batteries: Remove the connection from the first battery in the bank’s positive terminal that is connected to the subsequent battery’s negative terminal.

Then, move to the next battery and follow the same steps until all of the batteries in the bank are disconnected from each other.

  • Removing the Batteries: Lift the batteries from the bank one at a time and place them on a level surface away from the golf cart.

Making your Golf Cart Battery last longer

  • Charge the batteries regularly. The batteries should be fully charged after each use.
  • Use a quality charger. A good charger will help to prolong the life of the batteries.
  • Keep the batteries clean and dry. Corrosion can damage the batteries, so it is important to keep them clean and dry.
  • Avoid over-discharging the batteries. Over-discharging can damage the batteries, so it is important to avoid running them down too low.
  • Store the batteries properly. The batteries should be stored in a cool, dry place.


Can I mix different battery types in my golf cart?

Mixing different battery types can lead to uneven charging and performance issues.

How often should I water my golf cart batteries?

Check water levels every 15-30 days, depending on usage, for flooded lead-acid batteries.

Can I use automotive batteries in my golf cart?

Golf carts require deep cycle batteries designed for continuous discharge, unlike automotive batteries.

What gauge wire should I use for my golf cart battery?

The wire gauge depends on the distance between the batteries and the controller. Consult your golf cart’s manual for the appropriate gauge.

Do I need to disconnect the batteries during the winter season?

If storing your golf cart during winter, it’s recommended to disconnect the batteries and store them in a cool, dry place.


The wiring of your golf cart battery significantly impacts its performance and lifespan. Following this guide, you can optimize your golf cart’s operation. Remember, safety precautions and regular maintenance are paramount for a trouble-free golf cart experience. For complex wiring issues, professional assistance is recommended.
