How to Get the Most out of Your Golf Cart Batteries

Frequently replacing golf cart batteries can become rather expensive and time consuming. Many cart owners also find it frustrating when their batteries need to be charged again after a short time. Fortunately, there are a number of ways to make them last longer. It’s particularly important to maintain and charge your batteries properly.


Overcharging your golf cart batteries may damage them. It is best to use an automatic charger that turns itself off when a battery is fully charged. Some older models lack this important feature. If you must use a manual charger, don’t forget to turn it off. You can set an alarm clock or timer to remind you when the battery is ready.

If possible, charge your batteries every day that you use an electric golf cart. Do not drive the vehicle until the battery dies; lead-acid batteries won’t last as long if you completely discharge them. It is also advantageous to begin charging a golf cart battery when there’s enough time to fully charge it before your next trip.

To make your batteries last even longer, consider using a Dual Pro charger. This sophisticated, dependable charging system is completely automated. Unlike most units, it precisely delivers the maximum charge every time. This increases golf cart battery life by at least one-fifth. You won’t have to charge or replace the batteries as often.


Remember to clean your golf cart batteries and check the water level each month. It’s vital to prevent damage by removing corrosion from the battery terminals. When watering batteries, use distilled water and pay attention to the water level markings. You can automate this process by using a battery watering system.


If you leave it on for a long period of time, any light bulb or electronic device can harm your golf cart battery by fully discharging it. You may have to jump-start a gas-powered cart if this happens. Remember to switch off the lights, radio and other accessories when you finish using them. Always remove the key before leaving your golf cart.

Driving techniques also affect battery life on electric golf carts. To get the most out of your batteries, avoid steep hills and don’t bring unnecessary items. Your passengers should not exceed the vehicle’s recommended weight capacity. If you need to move the cart a long distance, consider using a truck or utility trailer to carry it.


If you follow all of these tips, your golf cart battery should last a minimum of five years. You will also gain the ability to travel longer distances between charges. When your cart’s battery stops working, be sure to recycle it and purchase a quality replacement. Units with high amp capacities usually last longer.

  • I bought new Trojan batteries recently they are a few months old now. My charger died and the cart has been sitting a couple of months with no charge in the batteries...when I buy a new charger will the batteries recharge? I heard they won't. Thanks

  • I recently bought a used ezgo cart and am having trouble with the batteries. It only travels 1 mile before they die and the cart is very slow.

    They are 5 years old, but I’ve tested each and they test as good. The water level is good.I have an external charger with auto shut off. I have no idea how good they were maintained before I bought it.

    Any suggestions would be appreciated.

    • David, The batteries may charge up and show a good voltage but that is only the first part of battery health. There may be a lot of sulfation that is not allowing the batteries to fully charge to capacity. I would do 3 things.

      Measure the Specific gravity of each cell of each battery using the directions at the link.
      Then equalize the batteries individually.
      Then measure the specific gravity again to see if there was a change and if they are now within an acceptable range. If not then its time to replace them.

      If its time to replace them then we can help with that. We have the best pricing. I would be interested to hear your results after you completed the steps. Be sure to let us know.

  • I have a club car with 48 volt batteries almost 4 years old with head and tail lights I run 20 to 25 minutes and the Eric charger recharge time is one hour. This seems fine to me for what I have. If the cart were driven 2 hours it would go 30 miles. At its average speed of 15mph. I have not done that yet so my question is does this seem like I am still fine with these batteries.And I try not to go to wide open throttle unless I have to thinking this save quite a bit of battery life and sacrifices little overall speed. Is this true. Thanks

    • Eric how far are you going on the 20-25 min trips. I would assume based on your information of 15mph you are doing about 5-6.5 miles in 20-25 minute span of driving. That being said you need to check the state of charge to see how far you depleted the battery and multiple it out. That would give you a rough estimate of the rough distance you could safely drive on a full single charge. I don't know the charger well enough to make a determination on how far the depth of discharge is based on a single hour charge. Does this make sense to you? To determine your State of Charge (SOC) use the table on Charging Deep Cycle Batteries under Section 6

  • My charger, after fully charging my batteries, always stays on. The needle that shows full charge on the charger will be down to 0 all the way left. But charger is still on, never turns off. Does this harm my batteries?

    • Im not sure what charger you have so I can not give a definitive answer. What I can say is that if you battery charger is also a battery tender, meaning that it is suppose to left on the batteries then you are okay. The needle being far left to 0 sounds like you have bad batteries though that are not taking a charge at all. Do you they still perform and hold a decent charge?

  • My charger is an auto charger on an older ezgo cart and it only charges for about an hour and half,, two max and seems to be gutless. Can't trust it to go too far before it dies. I've added water, brought each battery up on an automotive charger and seemed better but now back on the cart charger seems poor again. I've got at least one battery that's bulgy and one battery that has tell tale signs of boiling over. Any thoughts ? Or am I just looking for new batteries period?

  • I work in a golf course cart barn and during the summer we are closed. What is the best way to maintain the batteries

  • The water level in my batteries was low this spring. I filled them with distilled water, and charged them. After that, the first time I took the cart out, it only lasted 9 holes. The second time it lasted 15 holes. Will the batteries work up to 18+ holes, or do I need to replace them? Thanks!

  • Battery charger dont stop charging and batteries swollen and overheated.they are 4 years old and i wondered if it was the charger or i need new batteries

    • @Graham, The batteries definitely need to be replaced but I also would consider replacing battery charger with something better so that your investment in batteries last longer. The other benefit to having a better battery charger is that the batteries will perform better as they are properly charged and maintained by the charger. In other words, you will be able to go farther in between charges and operate gold cart longer on a charge.

  • I bought new golf cart batteries one year ago. I just got the cart out of winter hibernation and have had each battery cell tested and they are good. I live on the coast but am not getting the miles per full charge now that I was last summer when used the cart almost daily.. Actually about 50% less mileage. Will the batteries efficiency increase with more regular use now that warmer weather is here? I do charge the batteries after every use and routinely check the distilled water levels.

    • @Greg..

      Your batteries sitting for the winter time might have built up a little sulfating on the plates. This basically does not allow the batteries to reach full capacity. You more than likely will not see an improvement as you begin to use them again. You may need to find a local battery company that can desulfate the batteries. This practice has mixed reviews on its effectiveness but its a great step to take before having to replace them. The brand of your batteries also plays into the behavior of there performance. Not all batteries were created equally.

  • One year old golf with one year old batteries and have used golf cart every weekend for two months. I put distilled water in it twice since I've got it and left the charger on it at all times when not in use as is what I was told by the dealer. When I got golf cart out of storing it for about 6 months with charger on and checked water levels and added distilled water as needed. Batteries will now not keep charge after an hour of use. I carried cart to dealer and the said batteries were bad. Did I do something wrong?

    • @Wayne - Great Question! Quick and simple answer, NO you did nothing wrong! However, there are a couple unknowns that will help paint the picture. Did you replace the batteries a year ago or did you buy a cart a year ago with batteries in it? Do you know that the batteries were 100% brand new a year ago? If so you do not know that they were handled correctly previous to your ownership of them. What brand is the battery and group size. Not all batteries are created equal. If none of that applies then I would look to that charger. Alot of people in the Las Vegas community(big golf community) replace there standard charger that came with the cart with a specialized charger that gives better performance. The charger may have cooked the batteries over the 6 months if it does not monitor the battery very well.

      Last question... How long before putting the cart in storage did the cart last on a full charge?

  • The hills and ridges put a huge strain on my golf cart batteries. I find myself replacing my batteries more than expected. I liked your article because I was wondering what else I can do to make them last longer.

    • Neil.. I think that the number one thing that will help your batteries is proper charging. Unless you live in a hot area like Las Vegas or Pheonix then charging seems to be most peoples problem. Look into a better charging system. You may pay more upfront for the charger but the cost savings in having batteries that are more reliable, last longer on a single charge and dont have to be replaced as often out ways it in my opinion. Happy golfing!

  • I've seen the question asked "How long does it take to fully charge batteries on electric golfcart" from some viewers on our blog.

    The answer is that it varies with each golfcart, charger and how deep the batteries are discharged. Typically it should range between 2 - 8 hrs on the factors mentioned.

    I hope this helps.
