The most important maintenance on an electric golf cart is battery care.

One way of thinking  about your battery pack is to think of it as a fuel tank. Proper use and care when charging golf cart batteries can easily influence how much service you get from your batteries and, to prolong their life your lead acid, deep cycle batteries require maintenance.

Before golf cart battery charging you will need to check a few things….

  • You should turn the ignition key to the “off” position. Even though there is no draw on the cart battery pack, it’s a good safe practice.
  •  Examine the outside appearance of the battery and ensure that the tops of the batteries and terminal connections are clean, free of dirt and corrosion, and dry.
  •  If fluids are on the top of a flooded/wet battery this may mean that the battery is being over-watered. If fluid is on the top of a gel or AGM battery this means that the battery is being overcharged and the performance and life will be reduced.
  •  During normal operation and lead acid battery charging, the batteries “gas”. The result is that acid will accumulate on the battery tops. This will cause corroded terminal connections and eventually frame damage.
  •  Clean the top of the battery, terminals and connections with a cloth or brush and a solution of baking soda and water. Do not allow the cleaning solution to get inside the battery. Rinse with water and dry with a clean cloth. It is highly recommended you use a 50/50 solution of baking soda and water to neutralize and clean the acid from the battery compartment. Once a month is recommended.
  •  Make sure that you check the battery cables and connections to ensure they are tight, clean, and free of corrosion. If the terminal connection is corroded it may cause a voltage drop between batteries and less golf cart battery life. It may also cause the cable to eventually fail due to heat caused by high resistance. Replace badly corroded cables with new ones. Make sure you apply a good coating of terminal protector after cleaning and before charging.
  •  Make sure that all the vent caps are secured properly on the battery.
  •  Apply a thin coat of petroleum jelly or battery terminal protector  Keep the area around batteries clean and dry.
  •  Proper deep cycle battery maintenance is imperative to maximize battery performance. Both under – or over-charging batteries can significantly reduce golf cart battery life. For proper golf cart battery charging, refer to the instructions that came with your equipment. Most chargers are automatic and pre-programmed.

 

Battery Cell Electrolyte Levels:

Before golf cart battery charging make sure each cell has the proper electrolyte level. Never charge a deep cycle battery if the electrolyte level is below the tops of the battery plates. Always keep the water at ¼” to ½” above the lead metal plates and only use distilled water. Never use Tap water, it has chemicals that can hurt the batteries. This will cause irreversible damage to the battery and shorten the capacity and life expectancy. If you discover this condition, simply add enough water to cover the plates before charging. Also, always check for proper electrolyte levels after charging your lead acid batteries.

During the charge process the electrolyte levels rise and, if you add too much it will be forced out of the cap vents causing a real mess on your golf cart floor and possibly cause corrosion in the battery tray. Battery manufacturers recommend distilled water or you may use your tap water if it tests below 200 parts per million of total dissolved solids.

Golf Cart Battery Charging:

Once you have the correct battery cell fluid levels and battery cables are clean and tight, its time to undertake your golf cart battery charging. Charge the batteries completely allowing the golf cart charger to shut off once full charge is met to enable good golf cart battery life.

The Battery Charger is designed to fully charge your battery set. If the batteries are severely deep cycled, some automatic battery chargers contain an electronic module that may not activate and the battery
charger will not function. Automatic chargers will determine the correct duration of the charge of the battery set and will shut off when the battery set is fully charged.

Never discharge a cart’s deep cycle batteries to the point that the vehicle will no longer run. This will shorten the life cycle of the batteries considerably, and may permanently damage the batteries. It is possible that the batteries will not accept a recharge if they are completely discharged. The deeper the discharge, the harder it is on the batteries.

Some golf cart owners believe that when it comes to golf cart battery charging you should not charge your batteries all the time, This is wrong..

You should start your golf cart battery charging even if the batteries have been used for only a short period (9 holes of golf or 10 Minutes). The golf cart charger is automatic and will turn off when batteries are fully charged. If the charger does not seem to operate properly, of if the batteries seem weak, seek a service professional. It is important to keep your batteries charged. A golf cart that has seen extended use (batteries used to half charge) and then left to sit for weeks or months with out re-charging can permanently damage your batteries as lead acid batteries will self discharge. Lead Acid batteries discharge even faster in cold weather during the winter months so it’s important when golf cart battery charging to keep your cart on the charger during the winter.

When Parked keep it Plugged-In: Do not leave your cart off of the charger for long periods. For example if you cart is fully charged, and you drive to the supermarket and back, plug it right back in when you get home. Keep in mind the more discharged your batteries are, the longer they will take to charge. Do not be surprised if they are charging for several hours (up to 16hrs). All charges should automatically shut off, if it does not then there is a problem that needs to be serviced.

 Golf cart battery charging Do’s and Don’ts:

  • Always disconnect the charger cord from the golf car after the car has been fully charged and the charger has shut off.
  •  Do not leave a cart unattended with the charger still plugged in for any extended period of time. Do not add acid to a cell. Trying to add acid to a battery with water in the cells is dangerous. Pouring sulfuric acid into a wet cell is not wise and can cause serious injury.
  •  Hot summer weather causes golf cart batteries to self-discharge at a much higher rate than in cold weather. For example, a healthy, fully charged set of batteries will go from 100% capacity to 50% capacity in just 9 weeks if left sitting idle at a temperature of 86 degrees. Imagine what happens at 95 or 100 degrees. Batteries are most vulnerable to sulfation when they are sitting idle and partially discharged.
  • Do not buy auto parts store brand batteries or you’ll be quickly disappointed. These are car batteries which are made differently and will not perform the same as deep-cycle batteries that are specifically designed for golf cars.

 

 Golf Cart Battery Charging Safety Precautions:

Always wear safety glasses and a face shield when working on or near batteries, particularly when golf cart battery charging.
All batteries generate explosive hydrogen gas. Keep sparks, flames and cigarettes away from batteries at all times.

Do not connect or disconnect “live” circuits. To avoid creating sparks, always turn charging and testing equipment off before attaching or removing clamps.
Perform all work in a well ventilated area. Never lean directly over a battery while boosting, testing or charging it.Batteries contain corrosive sulfuric acid that can destroy clothing and burn the skin. Neutralize any golf cart battery charging acid spills with paste made of baking soda and water or large quantities of water.

How to test a golf cart battery charger is a very common question

How to test a golf cart battery charger is a question that troubles many golf cart owners. Often golf cart owners say that their battery charger does not work, or that it will not kick on and is showing no signs of life.

The first question to ask yourself is how long has it been since you’ve charged your batteries ?  It’s possible that the batteries may not have enough voltage in them for the charger to start working. 

An automatic golf cart battery charger needs a minimal amount of voltage in the batteries to even start working. They need somewhere in the range of 20-35 volts in the batteries to allow the chargers to know that they are connected up to batteries and to kick on. To find out for sure whether your batteries are the culprit, you’ll need a Digital Voltage Tester to test each individual battery. You’ll want to completely charge your golf cart before testing.

The Electric Golf Cart Battery Guide at $19.99 is very worthwhile having

Very often it’s a battery problem. What’s the easiest way to determine whether you have a charger problem ? Test your charger on another cart, or test another cart’s charger on your cart.

Knowing how to test a golf cart battery charger is fairly simple

.You should check the amount of power your battery charger generates by connecting a voltmeter to the positive and negative clamps of the charger.

The needle on the voltmeter will move from left to right to show the amps available.

The extreme left means the battery has no power or amps while the extreme right indicates maximum amperage.

A golf cart battery charger can register as many as 36 amps on a voltmeter.

Don’t forget to look at the cables on the battery charger. Turn the ignition to auxiliary. If the golf cart battery charger doesn’t turn on then there is a problem with the connection between the charger and the battery.

Check the battery charger transformer by listening for a humming sound. Also ensure that the AC power cord is plugged in to a working outlet.

If the battery is getting electrical current then you should hear the transformer humming.

Track the wiring circuitry of the battery charger. In the owner’s manual there is a wiring diagram for the golf cart. There needs to be a continuous connection from the battery charger to the battery for power to run continuously.

Look for any frayed wires, cut wires and corrosion on the terminals of the battery.

Search for the grounding wire from the battery charger. It will be a single wire that comes from the charger and attaches to the metal frame of the golf cart inside the engine housing.

A disconnected ground wire stops the battery charger from charging the battery.

Find the charger fuses in the service panel on the back fender of the golf cart. If the battery charger fuse is blown the battery won’t get a charge.

Pull the caps off the battery terminals. If the liquid is gray or brown then the battery needs replacing and won’t charge.

Feel the battery charger. Overheating cause it to malfunction. Make sure that the battery charger is clean of grime and debris as any type of corrosion can cause overheating.

Make sure you wipe down the battery charger after it rains.

Warning when testing a golf cart battery charger

You must think safety when you’re working around, and with, batteries. Remove all jewelry. You should use gloves that do not conduct electricity when checking the wiring circuitry.

As batteries age, their maintenance requirements change. This means longer charging time and/or higher finish rate (higher amperage at the end of the charge).

Usually older batteries need to be watered more often. And, their capacity decreases while the self-discharge rate increases.

If your electric golf cart experiences “shuttering”, you can take it to mean that it has low voltage. “Shuttering” could also be an indication that your charger is not functioning properly.

Do not assume that you need to buy a new charger just because your golf cart battery charger does not work. However, if you know that the batteries need charging and the ammeter will NOT go above 15 amps, then you probably have a faulty charger and it must be repaired.

If the battery pack voltage is too low the charger WILL NOT come on! This usually leads one to think the charger is bad.

Chargers are fairly simple devices but there are several common failures that can be inexpensively and easily fixed. Other failures, such as a burned up transformer, or a bad circuit board can get rather expensive.

Common failures in golf cart battery chargers: 

Timer units, diodes and bad DC charger plugs are the most common failures in golf cart battery chargers.

Be sure to disconnect your charger from the house AC and from the golf car if severe electrical storms are nearby. Also disconnect the charger if you are leaving for an extended stay away. Batteries in good charged condition will keep most of that charge for several months.

Most modern “automatic” battery chargers require a minimum voltage be present in the battery bank prior to the charger powering up and recharging.

Finally, keep in mind that even under the best of conditions, most lead acid batteries only last 5-6 years. If they’ve been sitting for 10 years, we suggest that you don’t even bother trying to resurrect them.

How much does it cost to repair a golf cart battery charger?

Obviously this depends. In general, with the cost of parts and service, a good estimate is somewhere in the range of $150 to $250.
