Frequently Asked Questions About ICON Golf Carts

AGM Batteries: All AGM batteries that come in your new ICON EV will be covered for a period of 2 years.

Lithium Batteries: All ECO Lithium Batteries will be covered for 8 years (3 years full replacement value, and 5 years prorated.)*

Lead Acid: While ICON EV does not currently install Lead Acid Batteries, we have included information on maintenance in our FAQ’s for older models.

Exclusions for coverage would include the following:

• Lack of maintenance 

• Undercharging the cart battery regularly

• Battery failure due to a third party outside electrical source or wiring issue 

• Tampering with the charger or charger algorithms.

PLEASE NOTE ICON’s proprietary ECO battery is the ONLY authorized Lithium battery to be installed on an ICON EV. Any other Lithium battery, including ECO, from any other supplier will void the ICON Warranty.

Park your car within the length of the supplied charging cable to an outlet. 

Try to utilize an outlet that is on its own circuit, or has extremely limited draw from other items on the same circuit. For instance, you will not be able to charge your car on the same circuit as your refrigerator or other high amp appliances. 

Once the cord is plugged into your outlet, you may now plug into your cars charge receptacle. You will notice that you have a charge indicator on the body. That charge indicator will always light up red once the charger kicks on. The charge indicator will go from red to yellow to green depending on the state of charge. 

Do not interrupt the charge cycle until the charge indicator is green. 

You can leave the charge cord plugged in at all times as the charger has a built in shut-off feature once it achieves a full state of charge. However, the charger does not act as a trickle charger and once it is off it will not turn back on unless it is unplugged from the car and plugged back in to the car.

Yes. New batteries are initially about 75% of their full strength. The following procedure will ensure they reach their full potential. The first 10 to 20 complete charge/discharge cycles are critical to ensure they reach 100%. 

New batteries should be charged before use and thereafter as follows:

1. Plug the vehicle in and leave until the charger shuts off by itself 

2. Drive to discharge the batteries to 75% of battery pack capacity (see chart for voltage readings or use 9 holes of golf as a reference point) 

3. Plug the vehicle back in and repeat the charge cycle. It is very important you let it charge until it is completely done. 

4. Repeat this for the first 10 – 20 cycles. By the 12th cycle you will notice an increase in power, speed, and run-time.  

Most importantly: 

– NEVER run the battery pack down below 50% of capacity throughout their entire life. 

– Never leave the batteries in a state of discharge for extended periods of time. – Recharge the pack every 2 weeks if the car is sitting idle or in storage, and when in doubt, recharge it.

Yes. All batteries, regardless of their chemistry, self-discharge. The rate of self-discharge depends on the type of battery, the age of the battery, and the storage temperature the batteries are exposed to. As an estimate, AGM and flooded lead acid batteries self-discharge approximately 4% per week at 80F.

Yes, batteries can freeze if they are left in a state of partial or complete discharge. As the state of charge in a battery decreases, the electrolyte becomes more like water and the freezing point increases. The freezing temperature of the electrolyte in a fully charged battery is -92F. At a 40% state of charge, electrolyte will freeze if the temperature reaches approximately 16F.

Yes, proper care of your batteries can maintain a longer life.

Here are some tips:

• Recharging slowly and keeping your battery well maintained are the best ways to extend the life of your battery.

• Recharge a deep cycle battery as soon as possible after each use to prevent sulfation.

• In warmer climates, and during the summer, watering is required more often.  Check the electrolyte levels and add distilled water, if required.  Never add electrolyte to a battery that is not fully charged,just add distilled water and do not overfill.  The plates must be covered at all times.

• High ambient temperatures (above 80F) will shorten battery life because it increases positive grid corrosion and growth.

• Deeper depth of discharge (DoD) will shorten the life of the batteries. For example, a battery with an average of 50% DoD will last twice as long or more as an 80% DoD; a 20% DoD battery will last five times longer than a 50% DoD.  For example, golf cart batteries will average 225 cycles at 80% DoD and increase to 750 cycles at 50% DoD.

• Loss of electrolyte due to heat or overcharging

• Lead sulfation from extended storage

• Undercharging

• Excessive vibration

• Freezing or high temperatures

• Using tap water which causes calcium sulfation. Use distilled water only!

• Positive grid corrosion or growth due to high temperatures.

AGM batteries are a great option to be used in golf carts. There are numerous reasons and advantages for this. However, there are a few disadvantages as well.

A few of the advantages include:

• The AGM battery is capable of charging slightly faster

• It provides a depth-of-discharge of 80%

• The batteries are spill-proof thanks to its acid encapsulation

• AGM batteries are resistant to vibrations

• They are less likely to have sulfation build up

• It has fewer electrolytes

• This battery works well in cold temperatures

A few of the disadvantages are:

• They can be sensitive to overcharging

• It must be stored in a fully charged condition

• Reduced life-span in hotter climates

Overall AGM batteries are a great option for use in golf carts. They offer high currents and are also spill-proof. You don’t have to worry about the buildup of sulfation and you also do not have to worry about watering the batteries. For most people, watering lead acid batteries on a monthly basis is a hated task. In addition, so many individuals improperly maintain their water level in the batteries which will destroy the batteries.

VERY IMPORTANT – If your vehicle wasn’t originally equipped with AGM batteries and you decide to make the switch. make sure to have your dealer update the chargers algorithm for proper charging.

Serviceable Batteries Only

Water is lost during charging. Therefore, the best time to water your batteries is always at the end of the charge cycle. However, if the electrolyte level is extremely low or the plates are exposed to air, add some water to cover the plates before starting the charge cycle. Distilled water only.

The amount of water (electrolyte) in a wet-cell battery should be 1/8″-1/4” below the bottom of the fill tubes that extend down from the opening of each battery. Only distilled water should be used to fill low water levels.

If you overfill the battery and no overflow is on top, the best thing to do is to stop filling and let it be. If there was overflow on top of the battery, remember that the overflow is acidic. DO NOT let it touch your skin or clothing.

Clean the overflow with a rag or paper towel by wiping directionally away from the ports. Do not let the rag or paper towel get wet enough to drip on other parts of the car. Dispose of rag or paper towel. Wear protective gloves and don’t get the substance on your hands.
