Golf Cart Battery Voltage

Golf carts typically use either 12-volt, 8-volt, or 6-volt batteries. In this guide, we will focus on 6-volt batteries. Most golf carts require four to six 6-volt batteries to function properly, so it is crucial to ensure that you purchase batteries with the correct voltage.

To determine the proper voltage for your golf cart, refer to your owner’s manual. If you cannot find the manual, you can usually find a digital copy online.

Alternatively, you can calculate the voltage manually using the following steps:

  1. Count the number of acid holes on one of your existing 6-volt batteries.
  2. Multiply this number by 2.
  3. Multiply the result by the number of batteries required to operate your golf cart.

For example, if your cart needs four batteries to operate and each battery has three acid holes, the calculation would be as follows: 3 (acid holes) x 2 = 6 volts (single battery voltage) x 4 (number of batteries) = 24 volts (required voltage for your cart).

Once you know the required voltage, you can proceed to purchase the appropriate replacement batteries for your golf cart.

Depth of Discharge

The depth of discharge (DoD) refers to the percentage of a golf cart battery’s capacity that can be utilized before requiring recharging. A battery with a high DoD can be discharged to a greater extent before needing to be replenished. If you anticipate using your cart frequently, it is advisable to opt for a battery with a high DoD.

For instance, let’s consider a golf cart equipped with a 48-volt battery that has been discharged by 50%. In this case, there would be 24 amps of power remaining. It is important to recharge the battery either after utilizing 50% of its capacity or when the voltage drops too low.

If your golf cart is used infrequently, the depth of discharge may not be a significant concern since you won’t be consuming as much power. Nevertheless, it is still an important factor to consider when selecting a golf cart battery.

Golf Cart Amperage

Think of amperage in relation to the fuel efficiency rating of your golf cart. Just as you want to know how many miles you can travel on a gallon of gas, it’s important to understand how long your 6V battery will last on a single charge.

Similar to the advantages of driving a more fuel-efficient cart, opting for a higher amperage battery comes with its own benefits. A battery with higher amperage provides greater power output.

A useful metric for determining battery efficiency is amp-hours (Ah). This measurement indicates the amount of amperage the battery can deliver over the course of an hour. In general, a higher Ah rating indicates better efficiency.

By considering amp-hours (Ah), you can gauge the battery’s ability to produce a specific amount of amperage over an hour. This information helps you assess the battery’s overall efficiency.

Golf Cart Deep Cycle Batteries

Many people are not familiar with the distinctions between car batteries and golf cart batteries. In reality, there are significant differences between the two.

Golf cart batteries, specifically deep cycle batteries, are designed to deliver sustained power over an extended period and reliably operate until they are 80% discharged or more.

There are two main types of deep cycle batteries: Flooded Lead Acid (FLA) and Non-Spillable (VRLA).

FLA batteries are filled with a mixture of acid and water, making them heavier compared to other battery types. They require regular maintenance, such as adding water to the cells, and if not properly cared for, they can leak. FLA batteries also generate hydrogen gas during operation, so it is crucial to use them in well-ventilated areas.

On the other hand, VRLA batteries belong to the non-spillable category of lead batteries. They are sealed and maintenance-free, eliminating the need for adding water. VRLA batteries do not produce gas, allowing them to be used in enclosed spaces, which makes them suitable for golf carts and RVs. However, VRLA batteries tend to be more expensive than FLA batteries.

Lithium Golf Cart Batteries

Lithium golf cart batteries represent the latest advancement in golf cart battery technology. These batteries offer numerous advantages compared to traditional lead-acid batteries, including extended lifespan, lighter weight, and higher energy density.

Due to these benefits, lithium batteries are rapidly becoming the preferred choice among golf cart owners.

When selecting a lithium golf cart battery, there are a few key considerations, such as voltage and capacity. However, the most important factor to keep in mind is the price. As lithium batteries are still relatively new, they tend to be more expensive than lead-acid batteries.

If you’re looking for affordable lithium golf cart batteries, it’s recommended to conduct thorough research to find the best deal that aligns with your budget and requirements. Additionally, prioritizing batteries with extended warranty periods can ensure that you maximize your investment.

Furthermore, it’s crucial to dedicate time to researching and reading reviews before making a purchase decision for lithium batteries.

The benefits of lithium golf cart batteries include:

  • 40% lighter weight compared to lead-acid batteries
