Does a golf cart battery need to be recharged?
In this regard, a higher voltage (although more powerful) often comes at a cost. That cost is that it can burn through more amps faster, draining the golf cart battery quicker, and requiring you to recharge more frequently.
How to test golf cart battery?
To test the quality and power of a golf cart battery, you’ll need a voltmeter, a load tester, and a hydrometer. The voltmeter will connect to the terminals at the top of the battery to read its voltage. The load tester uses the same terminals to pump the battery full of current and assess how the it handles high levels of amperage.
How many volts does a golf cart battery use?
If it still doesn’t work, you need to replace the battery. Almost every golf cart uses multiple smaller batteries to achieve a total power of 36 or 48 volts. You probably have a series of 4 volt, 8 volt, or 12 volt batteries that combine to reach 36-48 volts. Test each battery separately.

What is load tester in golf cart?
A load tester assesses how the voltage in a battery is effected when there’s a lot of current running through the battery. It’s possible that your golf cart battery’s voltage is fine when it’s not being used but has a ton of resistance or struggles to handle high currents, causing the battery to die.
How to tell if battery is capable of achieving voltage?
A drop between 1-2 volts is to be expected when performing a load test. If the voltage drops more than 3-4 volts though, it’s a sign that the battery is capable of achieving the necessary voltage but won’t maintain that voltage when a current is passing through it. If this is the case, replace your battery.
What is the CCA of a battery?
CCA refers to the battery’s maximum power output when it’s 0 °F (−18 °C) outside. It’s a universal measurement for calculating the power of a battery.

The Basics
First, all batteries are not the same. So, for this purpose, we will stick to flooded cell lead acid batteries commonly used in golf carts. Testing other batteries such as AGM, Lithium, Gel or other battery chemistries may require specialized procedures which differ than those outlined here for lead acid varieties.
Symptoms
Possible symptoms of a failing battery or batteries could include the following:
Hydrometer
The first method of testing is to use a hydrometer, which measures the density of the electrolyte. This is accomplished through a specific gravity reading. Specific gravity is always compared to a baseline density of water, which is 1.000.
Load Tester
The second method of testing a golf cart battery would be to use a load tester . With more than 35 years of experience at our local shop, we have found that this testing method will often provide a more accurate result in a shorter amount of time. A battery load tester is a simple DC heating coil which is connected to a volt meter.
Discharge Machine
The last method of testing a golf cart battery would be to use a discharge machine . They are often expensive and not practical for home use, but most dealers have one.
How many volts are in a golf cart battery?
Now that we understand the differences between Amperage and Voltage, we can begin to break this down so we can locate the differences between various battery packs. For standard golf carts, we will typically see a Six Eight Volt Battery System. This can be visually determined by locating six batteries with 8 cells per battery. A cell is distinguished by a battery cap that is used for watering the batteries. With batteries used in Golf Carts, each cell will represent 2 Volts. Let’s take a look at the 5 most common battery packs we see in the market:

How powerful is a golf cart battery?
Let’s take a close look at Voltage in a battery pack. For comparison, we like to take a look at cars since we are familiar with horsepower and miles per gallon (MPG). Therefore, voltage in a battery pack inside of an electric golf cart has to do with power. It does not have to do with fuel. Therefore, voltage in a battery pack within a golf cart will be comparable to the horsepower in a car. With this knowledge in place, we can determine a 72 volt system can be more powerful than a 48 volt system, and a 48 volt system can be more powerful than a 36 volt system. If you took notice, we said that it “can” be more powerful. The reason for this is due large in part to the controller inside the vehicle. A controller determines how much amperage is delivered from the batteries to the controller.
How to tell if a golf cart battery is 6 volts?
A 6 volt golf cart battery can be identified by seeing batteries with 3 cell caps on top of the battery indicating 2 volts per cell. Generally speaking, a single 6 volt battery will have the highest amperage capacity and will allow for the greatest range in an 8-6 volt battery system.
How much are batteries for a golf cart?
Pricing varies from pack to pack. The general consensus for golf cart battery replacement ranges from $600 on the low end to $1600 on the high end. If you are buying batteries in the lower end of the price range, then they are most likely cheap golf cart batteries that will not last as long (you really do get what you pay for when it comes to batteries). Some packs cost as much as $2500 when you start dealing with 72 Volt systems and sealed for lithium batteries. But, for the typical lead acid battery pack, $900 to $1500 is about the norm. This price range is assuming you are working with a local golf cart dealer.

A 12 volt battery can be identified by seeing batteries with 6 cell caps on top of the battery indicating 2 volts per cell. A single 12 volt golf cart battery will have the least amperage capacity and is commonly used in 72 volt battery systems which are not terribly common among golf carts. EZGO golf cart batteries are known to be use 4-12 volt battery systems in some of their golf cart models.
Why are golf cart batteries so expensive?
Simply put, Golf Cart Batteries are expensive because you aren’t visiting the gas station every week. When you purchase them, you are essentially pre-paying for fuel. Yes, you still have to charge the vehicle, however the electricity cost usually breaks down to pennies per mile. In some studies, it was shown a golf cart costs less than $.02 per mile to operate in terms of electricity cost. Buying higher quality batteries versus cheaper ones will be better in the long run and will actually cost you less since you are replacing them less frequently.
