Golf carts are a great investment if you spend a lot of time on a golf course. If you decide to purchase an electric golf cart then one thing to consider is the battery, how often it needs replacing and what the best battery is!
Finding the best golf cart battery from day one means less time and money spent replacing it over time. So how do you find the best battery? In the following article, I’ve highlighted a few key things to consider before making your purchase as well as recommendations for the top-rated golf cart batteries available!
🏆 Quick Look at the Best Golf Cart Batteries 🏆
Before we dive in let’s quickly explore the difference between voltage and amperage. Understanding the voltage and amperage of your cart batteries is important as you can reduce the cost of replacing them more frequently. So let’s take a brief look at this information.
The voltage of a battery in a golf cart is directly related to power. A common misconception is that the higher the voltage the better, this isn’t always the case. We believe that a 72-volt system can be more powerful than a 48-volt and a 36-volt less powerful than a 48 volt. Realistically the power of the battery is determined by the amperage being delivered. The higher the voltage the higher the capacity for power.
Now that we understand voltage a little better we know that the real power lies in the total amperage. A good comparison of the amperage is like fuel in a car, you can have a powerful engine but without any fuel, you won’t be going anywhere. The more amperage you have in a battery pack the more distance you can cover before needing another charge.

When to Replace Golf Cart Batteries
Knowing when it’s time to replace the battery is a good skill to have, this means you will be able to get optimal use out of it. There are a few big signs that your cart will show when it’s time to replace the battery.
Increased Charge Time
If your golf cart now takes twice as long to charge compared with when you first got it then the battery needs replacing. The speed at which they charge is a great indication of the performance and capability.
Golf Cart Loses Power
A full charge should give you a minimum of 7 miles or more within your golf cart. This does vary depending on your cart so it can be a good idea to monitor the distance a full charge gets you from the start. If you struggle to get through 9 holes on a full charge then this is a very telling sign of a weak battery.
Everything is compared relative to when you first got your cart – the speed of acceleration is pretty quick with electric carts. If you notice the cart slowing, struggling to climb hills and small inclines then this is a very big sign of a bad battery. Especially if it was fully charged.
Physical Wear on the Battery
In very extreme cases or if you have ignored all the previous warning signs then the battery will show signs of wear. Generally, they will expand and have bulges on the casing of the battery and in some instances leak acid out the side.
Volt Meter Test
Just like with a car battery you can also have your golf cart battery read with a voltmeter. If your battery is a 48V then at full charge a voltmeter would read slightly higher at around 51-52 volts. Testing the power of your battery after some use is a great indication of the battery quality. Testing each battery individually is also a good idea, in the case of 1 faulty battery it is much cheaper to replace.
Battery Pack Power
Different batteries will offer different power and distances. In a standard golf cart, you can expect a size 8V battery system in use. Further breaking this down means there are six batteries with 8 cells per each battery.
A battery cell is distinguished by a cap that is actually used for watering them. A cell will typically be the equivalent of 2 volts in a golf cart.
The following table highlights the most common battery packs within the golf cart industry.
|Total Volts||Approx. Travel Distance|
6 x 6 Volts
4 x 12 Volts
6 x 8 Volts
8 x 6 Volts
|6 x 12 Volts||72 Volts||
A standard round of 18 holes will be roughly 5-7 miles. Using this simple chart you can see the kind of distances achievable for different battery packs.
If you only ever plan to do 9 or 18 holes then you can really choose any of the battery packs above. if you prefer not to charge your cart every other day then opt for an 8 x 6-volt battery system.
Other Considerations with Batteries
So, now you know the voltage and best system for your golf cart, what are the other things that need to be considered before making your purchase?
There are three basic types of golf cart batteries and they are all slightly different.
Flooded Lead-Acid Batteries
These are by far the most common type of battery, available in a number of sizes, are not sealed and are very versatile. These batteries have lead plates that are based on sulphuric acid.
Gel Lead-Acid Batteries
Completely sealed these batteries are great for those who always find them off the fairway and in rough terrains. There is a thickening agent within the battery that keeps the electrolyte still.
AGM Lead-Acid Batteries
A fiberglass separator is used to keep the electrolyte in place, these are a new design when it comes to batteries but are considered very durable. Spill-proof and resistant to any vibrations these batteries can withstand rough use.
Not all batteries will last the same amount of time. They are generally good for a certain amount of cycles which is the charging and discharging of electricity. This is unavoidable because every time you use it, drain it and recharge it you are chipping away at the life cycle. As a rule of thumb a battery can go through around 750 cycles which is considerable.
How to Clean Golf Cart Batteries
There are a few things one can do to prolong the life of the battery and they include.
Water the Battery
Using distilled water you can pour a small amount over the battery plates, when I say small I mean ¼ of an inch, any more and the unit will be prone to corrosion.
Clean the Connections and Terminals
Using a brush terminal cleaner specifically for the job or a wire brush, remove dust and dirt that can build up on the batteries. If there is acid present than use a small pinch of baking soda and clean it with water.
Charge as per the User Manual
Depending on your battery and cart directions you may need to charge it after every use or only once the battery is completely flat. Be sure to check your manual before use.
If you don’t use your golf cart all year round then be sure to store the batteries in the correct way when not in use. In winter, your fully charged battery needs to be stored in a warm place. Vice versa for summer.
