Golf carts rely on batteries for power. To keep it running smoothly and ensure it lasts a long time, it’s important to regularly check and maintain its batteries. In this blog, we will provide you with step-by-step instructions on how to check golf cart batteries, allowing you to identify any issues and take necessary measures.
How to Check Golf Cart Batteries
There are several methods available for checking or testing golf cart batteries. To ensure better health and performance, the simplified ways to test golf cart batteries are given below.
1. Hydrometer Testing
This method is used to measure the specific gravity of the electrolyte solution within each battery cell. By checking the specific gravity of the water in the battery, this test can help you detect issues with terminals, cells, or the battery itself in terms of charge processing and retention. The technique of how to check golf cart batteries with a hydrometer is stated in the following pointers:
- Using a hydrometer, extract a sample of the electrolyte solution from each cell.
- The float of the hydrometer will show the specific gravity, which should exist in a certain range for a fully charged battery.
- If the specific gravity readings come between 1.100 and 1.220, you will have to start recharging, while if it ranges from 1.225 to 1.265, the battery should be ready for testing.
- If the readings of specific gravity come around 1.280, it indicates the conditions of a good battery.
- If you observe a deviation of more than 50 points from 1.225, the reading indicates that the batteries are in poor condition and need to be replaced.
Take temperature corrections into account and note that discharged batteries usually do not show significant differences in specific gravity.
2. Load Testing
The load testing method tests the battery’s capacity to handle high levels of amperage. By connecting a load tester to the battery terminals, a substantial amount of current is applied to assess its performance. This test checks golf cart batteries and determines if you rely on their performance or not.
- Use a load tester, which consists of a basic DC heating coil connected to the measuring instrument called a voltmeter.
- Connect the load tester to the terminals of the battery and track the displayed voltage.
- Next, you can press the button on the tester to activate a resistor and apply a dummy load to the battery.
- Monitor the voltage range under this load to test the battery’s condition.
- A good battery should experience a voltage drop of 0.2 to 0.4 volts only, whereas a drop exceeding 5 volts suggests a defective battery.
However, for an 8-volt battery, it should sustain a voltage of 7 volts for a duration of 15 seconds, aligning with the advertised Ah (ampere-hour) rating. So, this is how you can check 8-volt golf cart batteries.

3. Individual Battery Testing
Here you can use a voltmeter to measure the voltage of the battery. Before starting to test golf cart batteries, make sure that the battery is fully charged.
- If accessible, test each battery separately using a voltmeter.
- This step is crucial because one bad battery can seriously affect the entire performance.
- After connecting the voltmeter to the battery terminals, if you are getting a reading of around 50-52 volts, it indicates the battery is in good condition.
- It is advisable to replace the batteries that show signs of failure.
Note that replacing the entire set of batteries could be a more cost-effective and practical choice in the long term.
4. Discharge Machine Testing
Among all the ways to test golf cart batteries, this technique is less common and requires expensive discharge machines. The method is discussed in the following key points.
- The discharge machine applies a 75-amp load to all the batteries simultaneously.
- It measures the time required for the batteries to reach a 75% depth of discharge.
- This test gives you an idea about the expected time of how long the golf cart will run under typical load conditions.
So, regular testing and maintenance of golf cart batteries are crucial for preventing issues, detecting damage or corrosion, and ensuring optimal performance. Following these guidelines will help ensure the efficient performance of your golf cart batteries. However, it’s advisable to seek professional assistance or contact the manufacturer for guidance on how to test your golf cart battery.
How to Check Golf Cart Batteries for Water
Maintaining the correct water level in your golf cart battery is essential for its long-term performance. Keep the water level in each cell above the lead element and about an inch from the top. It is important to avoid overfilling the battery and keep it approximately ¼ to ½ inches above the plates.
When it comes to refilling your golf cart battery, there are some additional considerations to keep in mind.
1. Firstly, avoid refilling water to a battery when it is discharged, as it can cause overflow and lead to acid leakage and corrosion.
2. To refill your golf cart battery, start by checking the water levels when the battery is completely charged. Only refill the battery when it is charged.
3. Additionally, use distilled water instead of regular water (tap water). It is because tap water may contain minerals and harmful chemicals that can disturb the battery’s chemical processes, while distilled water is pure and free of contaminants.
4. Ensure that the battery plates are adequately covered and not exposed. If the plates are exposed, it is time to add water. You can use a funnel or a battery water filler to make the refilling process easier.
5. Allowing the water level in your battery to drop too low can have serious consequences. It can cause the plates to dry out and flake off, making the battery unable to recharge. This may lead to the need for battery replacement and can pose risks of overheating or fire.
In this way, regularly inspecting and maintaining it will help to extend the lifespan of your golf cart batteries. So, how often to check water in golf cart batteries? Well, the frequency of refilling your golf cart battery depends on your usage.
- If you are an average user who operates their golf cart a few times per week, it is recommended to check the water levels and refill them on a monthly basis.
- However, if you use your golf cart daily, monitor the water levels two or three times per month.
How do I Know if My Golf Cart Batteries are Bad?
To determine if your golf cart batteries are in good or poor condition, there are signs you can look out for. So, how to check if golf cart batteries are good? By observing these signs, you can tell whether it’s time to change the batteries or seek professional guidance.
1. Incorrect Voltage Readings
Check the voltage of your fully charged batteries using a voltmeter. If the reading is below 48 or 50 volts, it could be a sign that your batteries need replacement.
2. Visible Battery Issues
Look for visible signs of battery deterioration. The most usual signs include acid leaks around the terminals, bulging, or any other deformations that require immediate battery replacement. Moreover, take precautions to prevent any contact with battery acid as it can pose potential hazards.
3. Loose Connections
Loose connections can hinder effective charging. So, ensure that all battery terminal connections and links between the batteries are securely fastened.

4. Longer Charging Time
If your batteries take longer time than usual to get fully charged, i.e., more than 12 hours, it indicates degradation in battery health. For better understanding, track the charging duration over a certain period.
5. Quick Power Loss
If your golf cart experience decreased power output and loses power faster than before, it is a strong indication of degrading batteries. This results in a shorter driving time between charges.
6. Decreased Acceleration
If you notice a decline in your golf cart’s acceleration and it feels less responsive, it could be due to its weak batteries. Over time, these batteries may experience difficulties in providing sufficient energy for rapid acceleration, which can have a negative impact on performance and handling.
So, regularly checking and replacing batteries can help you to check if golf cart batteries are good or bad. If you observe any of these above-mentioned signs, it is recommended to consult with a golf cart battery specialist to confirm the condition of your batteries. Moreover, note that after changing batteries, proper disposal of old golf cart batteries is crucial to avoid harm to the environment.
