If there is one thing that can be overlooked when looking at an electric Golf Carts batteries then it would have to do with determining voltage and amperage in golf cart batteries essentially the difference between 36 Volt on up to 48 Volt systems. If the hydrometer has a temperature correction chart be sure to adjust the reading for the batterys temperature.
Check the battery pack voltage when the cart is at rest and after 12 hours when it was last charged.
Checking 36 volt golf cart batteries. Batteries for a 36 Volt Golf Cart 6V Batteries. To best protect your batteries make an effort to wipe down golf cart batteries every month or so. Each holecell is equal to 2 volts.
For example a 48 volt system will have 51 to 52 volts after a full charge. 3 holes X 2 volts 6 volt battery. So for example a 36 volt battery charger would require approx.
Dispose of your battery carefully as lead-acid batteries can be an environmental hazard. Take a measurement from the positive of the first battery in the bank and the negative in the last battery as seen in image above. I use it in a paved rv resort park and so the seems to be a problem.
After fully charging the carts battery rack use the multimeter Set it to 200v DCacross the posts of each individual battery. Turn the key to the forward position and note the dip in voltage with the meter still connected. Is there something that would keep the car with low power when the battery are fully charged.
For 48v carts if any battery reads below 93v and is not within 05v OF ANY OTHER BATTERY in the set. If the specific gravity is between 1225 and 1265 the battery is ok to test. The first thing to check is the timing mechanism.
If the specific gravity measures between 1100 and 1220 the battery must be. I reviewing the install process of a 36 Volt Golf Cart. How To Test Golf Cart Batteries Four Methods.
If you have a controller golf cart check the throttle potentiometer to see if it reads 0 Ohms at rest not more than 10 Ohms when the solenoid is activated and rises to 5000-5500 Ohms at full throttle. The Two Different Methods of Testing Golf Cart Batteries When it comes to testing golf cart batteries there two methods that you can use. Well a 36 volt battery bank is measured two ways to get the full charge reading for your EZGO golf cart.
How To Test Golf Cart Batteries With A Multimeter. Going over how 6 volt batteries are tied into series that creates a 36 Volt system. Get a brush for cleaning off corrosion and rags for wiping off leaking acid.
You can do this without disconnecting the batteries from each other as long as you test across one batterys posts. Your golf cart battery charger will either have a manual mechanical timer or an automatic electric timer. Typically a charged battery pack will have 2-3 volts higher on a charger than its rated voltage.
If it is a manual timer its pretty easy to test. 25-30 volts to activate whereas a 48 volt charger would require 30-35 or even 40 volts present to activate. Now for 36v carts if any battery reads below 70v and is not within 05v OF ANY OTHER BATTERY in the set.
I have used carts before on the course and there was no problem with the cart. If you see leaking acid remove the battery immediately and replace it. We can test this by using a Volt.
You can take a multimeter and set it to measure voltage. One is by using a hydrometer and the other is by using a multimeter or a voltmeter. For 48v carts with six 8v batteries were looking for at least 93v on each battery.
Always test fully charged batteries at room temperature. What to Know About Voltage and Amperage in Golf Cart Batteries. Jack up the golf cart and check if the hubs are out of alignment.
3 Multiply the number of holes by 2 to determine the golf cart battery voltage. Turn the timer on and check for power coming from the timer. Both of these methods are very accurate and provide accurate results.
Remove the white and black wires connected to the controller to do the check. 4 Multiply the golf cart battery voltage by the total number of golf cart batteries. I have a used 4 wheel ezgo 36 volt golf cart Marathon with new battery and i find it sluggish when not pulling much of a hill.
Most older style golf cart battery chargers require approx 75 of the chargers operating voltage present to activate. Also check each battery voltage individually using a digital voltmeter. Replace the battery if its faulty.
Another way to see how your batteries are holding up is to test the voltage of the golf cart batteries. Others require a little less.
