Understanding Golf Cart Batteries

To pick the best golf cart battery, it is important to first learn the basics. Here are the most common questions and answers about battery life span for electric golf cart batteries, how to test batteries, how to determine their duration, and more.

What Are Golf Cart Batteries and Their Advantages?

Golf cart batteries are different from car starter batteries. They are deep-cycle batteries that can be deeply discharged when powering electric golf cart batteries for several miles. Some outstanding golf cart deep-cycle battery manufacturers are Trojan, Lifeline, Amstron, Ampere Time, and Expert Power.

These batteries have several advantages when compared with other models. They have longer life spans, great capacities, resistant casings, and even have the proper terminals for this electric vehicle.

What Are the Main Golf Cart Battery Types?

There are different battery types like the Flooded, Gel, AGM, and Lithium golf cart batteries. Lithium-ion golf cart batteries have high capacities but also come at a high price. Sealed lead-acid (SLA) Gel and AGM golf cart batteries have a good capacity, amperage, and performance for only a fraction of the price. Flooded batteries have a low price, but they have low depths of discharge and require regular maintenance. The AGM battery is one of the best options available for golf carts.

How Do Golf Cart Batteries Operate?

Golf cart batteries operate similar to other batteries. They use chemicals like lithium salts or sulfuric acid for the electrolyte and have plates that work as the anode and cathode. When discharged, the battery goes through a chemical reaction that generates an electrical current that powers the load. Meanwhile, the opposite reaction occurs when the battery is being charged.

How Long Do Golf Cart Batteries Last?

Some of the best golf cart batteries have warranties of 4–5 years. With proper usage by discharging it to the recommended 50% depth of discharge (DOD) and charging it with the parameters set by the manufacturer, a golf cart battery can last for 6 years or more.

How to Test Golf Cart Batteries?

The simplest way to test a golf cart battery is using a voltmeter. The voltage reading will indicate if the battery is properly working. Some golf carts require 6- or 8-volt golf cart batteries, while others requiring 36V or 48 volt golf cart batteries might have several 6V or 12V golf cart batteries in series.

Each battery should read a voltage close to or superior to its nominal voltage. Six-volt golf cart batteries read 6.2–6.3V. You can use this to calculate the voltage for your battery. For instance, 36-volt golf cart batteries are the same as 6 x 6V batteries, and they should read 37.2–37.8V.

How Long Do Golf Cart Batteries Last on One Charge?

The distance a golf cart can ride with a single charge depends on the cart consumption and battery capacity. 12V Golf carts consuming 56 amps at 12 mph might run for 102 minutes or 54 holes with 100Ah 12-volt golf cart batteries. 8V golf carts with 56 amps consumption at 12 mph might ride for 23.4 miles or nearly 60 holes with 115 Ah 8v golf cart batteries installed.

How Would You Know When Golf Cart Batteries Are Dying?

The best way to know if your golf cart battery is dying is to test it with a voltmeter. Each battery should give a reading equal to or superior to its nominal voltage. 6V batteries should read 6.2–6.3 volts. If the battery reads 4V, it means the battery is dead. For instance, 48-volt golf cart batteries are the same as 8 x 6V batteries, and they should read 49.2–49.8 volts. If it reads 32V or less, the battery is probably dead.

Buyer’s Guide

Now that you know some of the best 6V and 12V golf cart batteries, it is important to know how to pick the best option for you from the list. Here, we show you some important criteria that you should consider.

What Is the Proper Voltage for Your Battery?

The voltage you need is defined by the requirements of the golf cart motor. The user manual for the motor of your golf cart might state this. If your cart requires 8V golf cart batteries, there might not be any other way than just getting that battery type. Given the case that you need 48V, 36V, or 12V golf cart batteries, you can just connect quality 6V or 12V batteries and install them in series.

How Many Amp-Hours Does Your Cart Need?

If your motor states the power in Watts (W), you can multiply that power by the number of hours that you are expecting to use the golf cart on a single charge. This will give you a reference of the capacity needed in Wh. Then, you must divide this value by the voltage that the manufacturer states for the battery. This will give you the resulting capacity needed in Ah.

Once you find that out, you can compare with the available battery model’s capacity (Ah). Remember that DOD affects the number of cycles that the battery can last. Therefore, it is recommended to compare the Ah that you need with the 50% DOD capacity (Ah) of the batteries under consideration. Moreover, you also need to consider the C-rate at which the battery will be working to estimate the number of hours that the battery will be able to run. This will depend on the electrical current (A) demand of your motor.

It is important to know, however, that the motor demands different electrical currents at different speeds. Although the plate should state at which speed the motor is rated for the nominal power, it is recommended to oversize your needed battery capacity a bit (by 20% ideally) to account for these variations in speed and acceleration.

What Is the Best Battery Type (Technology) for You?

While the motor of your golf cart might require a certain voltage and amperage to properly function, choosing the battery technology is up to you.

  • Lead-acid flooded batteries provide a medium capacity, but they usually have a maximum 50% DOD.
  • Sealed lead-acid Gel and AGM batteries have similar capacities to flooded ones, but with the possibility to reach an 80% maximum DOD, you get more efficiency for a really good price.
  • Lithium batteries have a higher capacity and DOD, but they have a much higher price.

Flooded batteries are usually the cheapest options, while the best ones considering specifications and cost are the sealed lead-acid AGM golf cart batteries.

How Much Do Golf Cart Batteries Cost?

Golf cart batteries have several price ranges depending on capacity, technology, and other specifications. Cheap golf cart batteries go as low as $50–$99, but they have very small capacities. Mid-end batteries range from $101 to $499, have higher capacities, and can ride for several miles. High-capacity batteries go for $500, but they provide the longest rides for this electric vehicle.

What Is the Warranty for a Golf Cart Battery?

The warranty of a golf cart battery usually depends on the technology. Lithium golf cart batteries have longer warranties, while AGM and Gel-sealed batteries can have up to 5-years warranties, and average flooded batteries usually have a 1-year warranty. As with any product, having a long-term warranty is a reference to quality and performance over time.

To extend the lifespan of your battery you should take proper care of it. You can do this by discharging the batteries to the recommended 50% DOD and charging them back up with a charger that allows the charging parameters set by the manufacturer.

What Size and Weight Should Your Battery Have?

Golf cart batteries usually have standard dimensions suitable for most golf carts. The weight does vary depending on capacity, technology, and design. Heavier batteries weighing 60 lbs or more tend to be more stable and provide smaller chances of falling out of the golf cart, making them much safer options.

Conclusion

With the proper golf cart battery, you can ride for hours and enjoy your favorite activities, be it golfing, riding around green areas at the country club, or anything else. This is why it is important to choose a battery with the proper voltage and a high capacity that will take you for longer distances.
