A golf cart battery is a little different from the 12-volt battery that you find in your car. It’s a collection of individual units linked together as opposed to the single-housing unit that cars use. When you want to test them, two of the most effective ways are using a voltmeter or a hydrometer.
How many volts is a 12 volt golf cart battery?
Average 12 volt golf cart batteries are 150Ah…. 8 volt battery will need to maintain 7 volts for 15 seconds at the advertised 20hr Ah rating, and then the 12 volt battery will need to maintain 11 volts for 15 seconds at the advertised 20hr Ah rating.
How to test golf cart batteries?
How To Test Golf Cart Batteries With Load Testing. A load tester will give you more insight as to the health of your battery. By putting a dummy load on the battery, you can see how the battery performs when actually being used. The load tester hooks to the terminals of the battery and displays the voltage.
What types of batteries are used in golf carts?

A fresh battery will plop down without bouncing. It may roll over onto its side, but won't bounce back up. An older battery will bounce up several times before falling over. Use the battery's behavior to tell if this is a fresh or old battery.
What should a 12 volt battery read fully charged?
A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
How do I test 12V power with a multimeter?
You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you've measuring a 12V battery, use the 20V setting.

Why is my golf cart battery undercharging?
Undercharging: Undercharging caused by using a cheap golf cart battery charging system ( One that does not apply enough amperage in the charging cycle) can cause lead sulfate to gradually build up and crystallize on the plates greatly reducing the. battery’s capacity and ability to be recharged.
What is the specific gravity of a battery?
If the specific gravity measures between 1.100 and 1.220, the battery must be. recharged. If the specific gravity is between 1.225 and 1.265, the battery is ok to test. If the hydrometer has a temperature correction chart, be sure to adjust the reading for the battery’s temperature.
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.
How to keep golf cart batteries from arcing?
1. Stay safe by putting on protective eyewear, gloves, and clearing your area. Golf cart batteries can arc, spark, or emit dangerous gasses while you’re testing them. Stay safe by putting on protective eyewear and wearing gloves to keep any gases from condensing on your skin.
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 do hydrometers work?
Inside, there are separate cells filled with water that cover a plate, which uses the electrolytes in the water as a conduit. Pop the top off of each cell and get a hydrometer that will fit in the opening for each cell.
Is it safe to load test a battery?
It doesn’t matter if the pressure is good if the hole is too small to let water out! Warning: Load testing a battery is actually kind of dangerous. The high level of current will generate a lot of heat in the load tester and battery. Only test a battery on a concrete or heat-resistant surface that won’t burn.
Can you smoke golf cart batteries?
Always attach the correct probe on your multimeter or voltmeter to the proper terminal or you may create a spark. Warning: Never smoke when you’re working around golf cart batteries and keep the area clear from any open flames. The hydrogen and oxygen in golf cart batteries can explode if they’re ignited.
What causes a battery to fail?
Batteries are subject to all manner of wear and tear, and any of the following things can cause them to fail: 1 Battery Age: This one is obvious; the older the battery is, then the more likely the failure is due to normal wearing from long-term use. 2 Overcharge : When people swap out chargers for more powerful units or just use another more convenient charger, the result can be heat and water loss. 3 Undercharge : Conversely, if someone has replaced the proper charging equipment with a cheaper lower-power alternative, then this causes problems. Specifically, you get a buildup of lead sulfate that crystallizes on the plates and reduces recharging capacity. 4 Overtaxing : Do you make heavy use of your golf cart’s additional electronic features? These might include radio, headlights, and other things. If you are using the golf car onboard electronics a lot, you will tax the battery more. 5 Corrosion : When the electrolytic fluid gets low, corrosion can occur on the battery connections. This easily and quickly reduces the battery’s life. 6 Incorrect Battery : Your golf cart will come with a recommended configuration of battery units. For example, it may require six 6-volt units. Some attempt to circumvent this by using three 12-volt units. The math works, but the performance ratings do not.
Is it safe to use a voltmeter or a hydrometer?
Batteries use a lot of hazardous ingredients and components, especially when you put the wrong things together. Using a voltmeter is arguably safer than using a hydrometer, but there are things you should do as a precaution in any event.
How To Test A Golf Cart Battery In The Most Efficient And Effective Way
