What Size Battery for E-Z-GO Gas Golf Cart? A Complete Guide

If you’re a golf cart owner or looking to purchase a new battery for your E-Z-GO gas golf cart, understanding the correct battery size is crucial. While gas-powered golf carts don’t rely solely on batteries for propulsion, they still need a reliable battery to power essential systems like lights, the ignition, and the dashboard. In this guide, we’ll break down the battery size options, factors to consider, and how to ensure you choose the right battery for your E-Z-GO gas golf cart.

Why Do E-Z-GO Gas Golf Carts Need a Battery?

Before diving into the specifics of battery size, it’s important to understand why a gas-powered golf cart needs a battery at all. In E-Z-GO gas models, the battery is used primarily for:

Starting the engine: The battery provides the necessary power to start the engine, much like a car battery. Powering electrical accessories: Items like headlights, tail lights, the horn, and the dashboard are powered by the battery. Ignition system: The battery is integral to the ignition system of the golf cart, ensuring that the engine starts reliably.

Because of these roles, the battery size and type must be compatible with your E-Z-GO gas golf cart’s requirements.

What Size Battery Do You Need for an E-Z-GO Gas Golf Cart?

The size of the battery for an E-Z-GO gas golf cart depends on several factors, including the model year, the specific golf cart type, and the battery’s capacity. However, there are some general guidelines you can follow when choosing the right battery for your needs.

Common Battery Sizes for E-Z-GO Gas Golf Carts

E-Z-GO gas golf carts typically use a 12-volt battery, which is standard for powering the electrical systems in gas models. However, the size and amp-hour (Ah) rating of the battery can vary. Here are the most common types:

1. Group U1 12-Volt Battery Size: 7.8″ x 5.1″ x 7.5″ (L x W x H) Capacity: Typically 35–45 Ah Usage: Suitable for most E-Z-GO gas golf carts built from 1995 to present. 2. Group 24 12-Volt Battery Size: 10.3″ x 6.8″ x 8.6″ (L x W x H) Capacity: Typically 50–75 Ah Usage: Ideal for older E-Z-GO gas models or carts with higher power demands.

Amp-Hour Rating: What Does It Mean?

When choosing a battery, the amp-hour (Ah) rating is an important consideration. This number indicates the capacity of the battery and how long it can supply power before needing a recharge. A higher Ah rating generally means a longer runtime for the accessories and systems powered by the battery, but it also usually means a larger, more expensive battery.

Example:

A 35 Ah battery may run the electrical systems of your golf cart for around 35 hours under a 1-amp load, while a 75 Ah battery would run for about 75 hours.

How to Choose the Right Battery for Your E-Z-GO Gas Golf Cart

Choosing the right battery isn’t just about size. Several other factors should be considered to ensure a good fit for your specific needs.

1. Check Your Golf Cart’s Battery Compartment

Make sure the battery you choose fits comfortably within the designated space in your golf cart. Measure the dimensions of the battery compartment before making a purchase, as some golf carts have limited space that may not accommodate a larger battery.

2. Consider Battery Life and Maintenance

Batteries vary in terms of lifespan and maintenance requirements. AGM (Absorbent Glass Mat) batteries are maintenance-free and offer a longer lifespan, but they tend to be more expensive than flooded lead-acid batteries. The latter requires periodic water maintenance but is more affordable upfront.

3. Match the Voltage Requirements

It’s important to choose a 12-volt battery that matches the voltage needs of your cart’s electrical system. For most E-Z-GO gas golf carts, this means opting for a 12-volt battery, but always refer to the user manual for confirmation.

4. Understand the CCA Rating

The Cold Cranking Amps (CCA) rating indicates how well a battery performs in cold temperatures. If you live in an area with harsh winters, a battery with a higher CCA rating is recommended to ensure reliable starting in low temperatures.

Top Battery Brands for E-Z-GO Gas Golf Carts

How to Maintain Your Battery for Longer Life

Proper maintenance is key to getting the most out of your golf cart battery. Here are some tips to help you maintain a healthy battery for your E-Z-GO gas golf cart:

1. Regular Charging

Always charge your battery after use, especially if you’ve been using your cart for long periods. Avoid letting the battery run down completely to prevent damage.

2. Check Battery Terminals

Clean the battery terminals regularly and ensure they are free from corrosion. Use a solution of baking soda and water to remove any buildup.

3. Watering (For Flooded Batteries)

If you’re using a flooded lead-acid battery, regularly check the water levels and top them off with distilled water as necessary. Avoid overfilling or underfilling.

4. Store in a Cool, Dry Place

If you’re storing your golf cart for the off-season, remove the battery and store it in a cool, dry place. Ensure that the battery is fully charged before storage to prevent it from losing charge over time.

Choosing the correct battery for your E-Z-GO gas golf cart is essential for maintaining its performance and reliability. Be sure to check the size, voltage, amp-hour rating, and battery type before making a purchase. Regular maintenance and using high-quality brands can ensure a long-lasting and trouble-free experience. Whether you choose a Group U1 or Group 24 battery, ensuring the right fit and specifications will help your golf cart perform at its best.
