Golf cart batteries are the main component of electric golf carts, which is the power source that enables the vehicle to move around the course. Proper golf cart battery maintenance is the key to the perfect performance, prolonging the battery life and preventing the need of expensive replacements. This article will be about golf cart battery maintenance, where we will share 10 important tips to help you maintain your batteries for a long time.
Whatever your role is, be it a golf course manager, a golf cart dealer, or a battery distributor, you should know the best practices for maintaining golf cart batteries in order to get the most out of your investment. Thus, let’s begin and delve into the details of golf cart battery care.
Tip 1: Carry out Periodic Inspections
Regular inspections are the basis of effective golf cart battery maintenance. At least once a month, make it a habit to check your batteries for any signs of trouble.
Check battery case: Look for any indication of physical damage, for example, cracks or leaks. The batteries that have been damaged must be replaced as soon as possible to prevent the occurrence of other problems.
Examine terminal connections: Make sure that the battery terminals are clean, the connection is tight, and corrosion is absent, which can affect the performance. A wire brush is used to remove the corrosion that is found on the metal.
Inspect battery cables: Look for the cable connections and see if battery cables are damaged, worn, or frayed. Broken cables may lead to electrical problems and thus, they should be replaced immediately.
Tip 2: Charge Batteries Correctly
Good charging is vital for the health and the life span of your golf cart batteries. Overcharging can lead to excessive gassing and water loss, while undercharging can result in sulfation and premature failure. Follow these guidelines for optimal charging:
Use the right battery charger: Make sure you are using a charger that is made for the type of battery of your golf cart and the voltage of it, whether it is lead-acid or lithium-ion. The usage of an incompatible charger can be the reason for the damage of the batteries.
For lead acid Batteries: Carry out an equalizing charge every month or according to the manufacturer’s advice. This leads to the equal distribution of the charge across all the cells and thus, the electrolyte is not stratified.
For lithium Batteries: Lithium batteries can be highly vulnerable to the extreme temperatures. Do not charge them in very hot or cold environments because it can affect the charging process and damage the batteries.
Do not stop the charging process in the middle of the cycle if you can, because this may lead to undercharging and thus, decrease the battery efficiency. The interruption is allowed when the battery is at least half full.
Tip 3: Keep the Water Levels Right
The water level in the flooded lead-acid batteries is the key factor for the proper functioning of the golf carts. The most suitable time to check the water level is once a month and if needed, top it up to the correct level depending on the local climate. Tap water has minerals that can be a cause of electrolyte contamination and thus the corrosion is fast. At all times, use distilled water or deionized water to top the batteries.
The water level in each battery cell should be full enough to cover the battery’s plates but not overflow into the vent caps. The plates can be left too exposed to air if there is not enough water, which will result in their drying up and deterioration. The excess of water can trigger the electrolyte to spill out during charging, thus, causing corrosion and the decrease of the battery performance. If you own sealed lead-acid or lithium-ion batteries, you don’t have to be concerned about the water levels, because these types of batteries are maintenance-free in this aspect.
Tip 4: Avoid Deep Discharges
Deep discharges are cases where a battery is emptied to a very low level of charge, usually below 20% of its capacity. This can be the case if you don’t recharge your golf cart after prolonged use or if you leave it unused for a long time, thus self-discharging the batteries.
Deep discharges are harmful for your golf cart battery health, especially for lead-acid batteries. When the battery is deeply discharged, the lead sulfate crystals that form on the plates during discharge become larger and harder to convert back into active material during recharging. Sulfation is a condition that may develop over time and it shortens the battery lifespan as well as reduces its capacity.
To prevent deep discharges, recharge your batteries as soon as you can after use, ideally within 24 hours. If you realize that you won’t be using your golf cart for a long time, such as during the off-season, make sure that you fully charge the batteries before storage and then recharge them from time to time to keep them in a healthy state of charge.
Moreover, Lithium-ion batteries are less vulnerable to damage caused by deep discharge, which means they are a good option for golf cart owners who often experience deep discharge situations.
If you do happen to let your batteries get down to the deep discharge level, don’t worry. You can do this by using a low-current charger like a trickle charger to slowly recharge them. This can help in disintegrating the large lead sulfate crystals and thus restore some of the battery capacity. On the other hand, remember that deep discharges beyond a certain level can cause irreparable damage, so try to avoid them as much as you can.
Tip 5: Use a Battery Monitoring System
A battery monitoring system (BMS) is a priceless tool for golf cart owners who want to enhance their battery’s performance and lifespan. It gives the real-time information on the state of charge, voltage, and temperature of every battery in the battery pack.
With the help of the state of charge, you can prevent the overcharging or deep discharging of your batteries, which can be the reason of the damage over time.
A BMS can also give you a warning about the possible problems like a weak or a faulty cell before they turn into the total battery failure. This means that you can take the necessary measures, like replacing the damaged cell or battery, before it causes any more harm or leaves you stuck on the course.
Although a BMS can be a great way to keep golf cart batteries in good condition, it is not a replacement for regular checks and proper maintenance. Consider it as a supplementary layer of security and supervision that will help you to make the most of your batteries.
Tip 6: Store Batteries Properly
The proper storage is very important for the health and the long life of your batteries, especially during periods of inactivity, such as the off-season.
In the case of battery storage, it is important to keep them in a cool, dry place, away from direct exposure to the heat or sunlight. The batteries can lose their performance faster and even get completely failed due to the extreme temperatures.
Ideally, batteries should be stored at room temperature, which is about 60-70°F (15-21°C). If you live in a cold climate, do not keep your batteries in a heated garage or shed, because the freezing temperatures can damage them irreversibly. If it is indispensable, a battery heater or the batteries should be moved to a warmer place.
Before the storage of your batteries, you have to fully charge them. This is the way to avoid self-discharge and at the same time, keep the batteries in good condition. If you intend to keep your batteries for a long time (more than a few months), it’s better to recharge them periodically, about once every 3-4 months, to maintain their charge and avoid sulfation.
While storing lead-acid batteries, ensure that the vent caps are tightly secured to avoid the entrance of debris or other foreign matter into the cells. If you are storing lithium-ion batteries, you should adhere to the manufacturer’s instructions on the proper voltage and temperature for storage.
In the end, do not store your batteries directly on the concrete floor, as this can lead to them discharging faster because of the cold. Rather than putting them on a concrete floor, they should be placed on a wooden pallet or shelf so that they can be insulated and the moisture can be prevented.
Tip 7: Make Your Golf Cart Usage A Regular Thing
Though it may appear to be the opposite, the regular usage of your golf cart can be an advantage to the life span of its batteries. Batteries that are left idle for long periods of time are more likely to get sulfated, a process where lead sulfate crystals accumulate and thus the capacity of the battery is reduced, which eventually leads to the battery failure.
If you reside in a climate where you can golf all year round, at least once a week try to take your cart out for a ride around the neighborhood even if it is just for a short ride. This will ensure your batteries always function well and be in good shape.
If your golf cart will be stored for a long time, you should periodically check the batteries by taking the cart for a short run or using a battery load tester to discharge and recharge the batteries.
When you do leave your cart out for a ride, you should use it for at least 20-30 minutes at a time. This lets the batteries to go through a healthy range of charge and discharge, which can in turn, make them have a better capacity and lifespan.
Nevertheless, be careful not to overdo it. Continuously draining your batteries to a very low state of charge can result in deep discharge damage, which is explained in Tip 4. Attempt to recharge your batteries before they reach the 50% level to ensure that your health is in the best condition.
Tip 8: Know When to Replace Your Batteries
Despite the regular maintenance, golf cart batteries will still eventually be at the end of their service life and hence need to be replaced. The knowledge of when to change your batteries is the main thing to be considered in order to prevent unexpected failure and to make sure the performance on the course is at its best.
The duration of golf cart batteries is determined by the kind of battery, the way they are used, and the way they are maintained. In general, lead-acid batteries last between 4-6 years, whereas lithium-ion batteries can last up to 10 years or more with the proper care.
Some signs that your batteries may be nearing the end of their life include:
| Reduced range | If you find that your golf cart is not going as far on a single charge as it used to, it could be a sign that your batteries are losing capacity. |
| Slow charging | If your batteries take more time to charge than they used to, or if they never reach a full charge, it can be a sign that they are wearing out. |
| Visible damage | If you see cracks, leaks, or too much corrosion on your battery casings or terminals, it’s a good idea to have them checked by a professional and possibly replaced. |
| Age | When your batteries are close to or over their period of use, it is time to start planning for a new set, even if they are still working properly. |
If you are not sure whether your batteries need to be replaced, you should ask a professional golf cart technician or a battery supplier for advice. They can do the load testing and other diagnostics to check the state of your batteries and give you a hint when to replace them.
Tip 9: Purchase the Best Quality Batteries
The initial investment in good quality batteries will be a time and money saver and will also save you from headaches in the future. Although premium batteries are more expensive to buy, they usually provide better performance, longer lifespan and easier maintenance than the cheaper, low-quality ones. Search for batteries that have higher reserve capacity, deeper depth of discharge capabilities, and longer cycle life ratings from reputable manufacturers that have a proven track record in the golf cart industry.
Besides the conventional lead-acid batteries, think of the advantages of lithium-ion batteries for your golf cart. Although they are more costly at the beginning, lithium-ion batteries have a lot of benefits, such as longer life, fast charging, and low maintenance. Through the combination of high-quality batteries with the correct care and maintenance, you can be sure that your golf cart will be always available to face the course with the reliable, efficient power.
