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 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.
Can I use a 48 volt battery in a golf cart?
Using a 48 volt Club Car for example you can play a round of golf with a new set of fully charged batteries and after round is complete the cart will still be above the 48 volt threshold on the battery banks capacity.
How much should you discharge a golf cart battery?
Use your golf cart and batteries often…avoid long periods of storage. 50% (or less) discharges are recommended. 80% discharge is the maximum safe discharge. Do not fully discharge lead-acid batteries (80% or more). This will damage (or kill) the battery.

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.

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.
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.
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 to test golf cart battery charger?

How many volts does a battery charger need?
Did you know that most modern battery chargers will not even begin to charge batteries if the batteries original charge is not high enough? The automatic battery charger needs a minimal amount of voltage in the batteries to even begin working, say somewhere around 20 to 35 volts total.
How long does it take for a battery charger to turn on?
With an automatic battery charger, the batteries must be hooked up before the charger will even turn on. allow 3 to 4 seconds for the time delay And if there is no click and a transformer hum, then we need to make sure that there is a proper connection between the battery charger and the batteries.
What to do if your car battery is too low?
If the batteries are too low, charge them individually with a regular old car battery charger, usually the12-volt variety. 12-Volt Automotive Battery Charger. You can either charge them to full capacity or just high enough to meet the minimum voltage required.
How to test a diode?
Test the diodes. Diodes are a one-way gate and will pass dc voltage in one direction. Connect your continuity tester leads on 1 and 3 shown in the illustration above…then reverse the leads. You should get continuity one way but not the other. Repeat this procedure on 2 and 3.
How to keep golf cart batteries charged?
Another good thing to have for your golf cart batteries is a watering system. Make sure you check the water level in your golf cart batteries monthly to make sure they are still saturated. ( always do this after your batteries are fully charged because if you check them and fill them before you charge them 100% you could over fill them and acid will leak out the top of the batteries while they charge and get all over your cart and in the garage or where ever you store the golf cart. Which is not good because battery acid will eat away at your concrete floor in the garage. Checkout Pete’s great deals on a new One point golf cart watering system to avoid over filling them and making a mess or getting battery acid on your cart, clothes or garage floor and do it with ease. ( In minutes – not an hour or more… weekends are meant to be spent with the family or watching the game not in the garage filling batteries… so get yours today!)
What to do if your golf cart battery hasn't taken a full charge?
If the battery has taken a charge, replace the cell caps and use your golf cart for a long ride and see how long the charge lasts.
