Replacement Batteries For Club Car Golf Carts

Club Car golf carts have been around for nearly 60-years, producing a variety of battery-powered golf cars, utility, and personal use vehicles. As most owners of these vehicles know, proper battery maintenance is key to longevity and reliability, but eventually, the batteries will need to be replaced. 

 

When it comes time to get a new set of deep-cycle batteries for your Club Car, it’s important to make sure you select the right ones for your particular application, and most importantly, the type of use it will see. Club Car’s battery specifications are different for the various model vehicles they produce. Most utilize a 48-volt electric engine but depending on the model, have different amperage and power requirements.

 

As an example, Club Car DS and Precedent models (2in1, 2Plus2, Cargo, Professional), XF (2in1, 2Plus2) and XF Cargo models take six BCI Group Size GC8 eight-volt batteries. Choosing the right one depends on if you use the vehicle daily or if it says in storage at your vacation home. For each of these types of scenarios, there are different battery ratings to choose from that might better match your usage needs. U.S. Battery’s US 8VGC XC2 (with a 20-hour rate of 170) is a great choice for those who want a longer-lasting battery for this application. The US 8VGCE XC2 (with a 20-hour rate of 155) offers less overall runtime for applications where the vehicle won’t be used daily, offering a more cost-effective solution.

 

Club Car Precedent Champion models also use a 48-volt system but utilize four BCI Group Size GC12, 12-volt batteries. U.S. Battery’s 12VRX XC2 (20-hour rate of 155) provides a great compromise between daily and occasional use. 

 

Proper Maintenance Makes The Difference 

 

To get the most performance from your new battery, you must develop a regular maintenance schedule that consists of:

 

1. Checking and replenishing the electrolyte levels. Installing a BWT or Flow-Rite single-point-watering kit can make this an easy and quick process.

2. Performing an equalization charge

3. Checking and Cleaning battery terminals and connections

4. Performing an opportunity charge when possible

SpeedCaps™ For Your Deep-Cycle Battery

U.S. Battery SpeedCaps™ Go Beyond Venting Deep-Cycle Battery Cells

The vent caps used on deep cycle batteries are designed to allow the escape of gases formed inside the battery when it is being charged and to limit the escape of electrolyte in normal operation. The vent caps are also designed for easy removal to visually check the electrolyte level in the battery and to add water as necessary.   They also allow for the insertion of a hydrometer to check the battery’s state of charge.  During regular maintenance that requires removing and reinstalling the vent caps, there is a possibility that the vent caps may not be properly reinstalled.  This could allow electrolyte to spill over onto the battery and cause corrosion on terminals and surrounding areas.

To improve on the standard battery vent cap, U.S. Battery SpeedCaps™ are designed with a cantilever-style closure that is attached to three or four battery cell caps. This design allows all the caps to be easily removed with a single twist. The design not only makes the removal of the battery caps easier, but it also ensures that they are properly seated when being replaced. The locking ramp on top self-adjusts to maintain compression between the sealing gasket and vent well surface for the life of the battery. SpeedCaps™ are designed to make your job of battery maintenance as hassle-free as possible while also maintaining a proper seal and gas venting during use.CAD drawing of U.S. Battery SpeedCaps

Proper venting is critical during charging when gas is being generated within the electrolyte and bubbles to the surface helping to mix the electrolyte. To prevent electrolyte from escaping past the vent caps, U.S. Battery SpeedCaps™ feature 0.750-inch diameter porous discs that assure proper venting while maintaining flame retardance to prevent gas ignition inside the battery. They also have four separate vent holes that decrease backpressure and prevent internal pressure buildup.

Since vent caps are removed and replaced frequently during regular battery maintenance, U.S. Battery SpeedCaps™ are designed with a larger diameter flange. The enlarged flange ensures even pressure on the surface of the sealing gasket while maintaining a tight fit between the barrel and cylinder to eliminate side-to-side movement and the chance for misalignment of the gasket onto the sealing surface.

To prevent spilling of the electrolyte during vehicle movement in golf carts, aerial platform lifts, RVs, boats, etc., the SpeedCap™ design also features a double-sided internal baffle with multi-directional channels and a sloped center hole return drain, all designed to route battery electrolyte back into the cell.

With all these safeguards in place, U.S. Battery SpeedCaps™ are an example of one of the many details the company adds to its products to ensure they provide optimum performance and cycle life compared to other deep-cycle batteries on the market.

5 Benefits To Using A Single Point Watering System

Anyone using deep-cycle flooded lead-acid batteries in their electric vehicle or other equipment knows the importance of routinely watering the batteries. During charging, the water content of the electrolyte will decrease due to the electrolysis of water into hydrogen and oxygen gases. If left unchecked, the electrodes inside each cell can become exposed, resulting in a loss of battery performance. Regular watering is essential to the continued life and performance of any flooded deep cycle battery.

Electric vehicles and other equipment using deep cycle batteries typically have from four to eight individual batteries – each with multiple cells. Watering each cell can take a significant amount of time, especially if you are maintaining a fleet of vehicles. Battery packs are often located in areas that are not easily accessible, increasing the time required for watering.U.S. Battery offers two single-point watering systems (SPWS), Battery Watering Technologies and Flow-Rite, that can make battery maintenance quick and easy while offering several other benefits.

  1. You Can Fill All Your Batteries At Once                                                                                                                                                                                                                                              A SPWS connects to all of the cells in each of the batteries within the pack allowing you to fill them with water from a single point.
  2. Save Time During Regular Maintenance                                                                                                                                                                                                                                         On a single battery-powered vehicle, you can water all of the batteries in about a minute, versus what would normally take 45-60 minutes per vehicle.
  3. No Chance Of Over Watering                                                                                                                                                                                                                                                            With an SPWS, the battery cells fill up to the proper level and shut off to prevent overfilling.
  4. Monitoring Systems Can Tell You When To Water                                                                                                                                                                                                                        Some SPWS offer a sensor that can monitor water levels in the battery and indicate when they need watering.
  5. Extended Battery Life                                                                                                                                                                                                                                                                    Frequent maintenance extends the life of your batteries which in turn lowers your annual operating costs.

AGM and Flooded Deep-Cycle Batteries

Understanding the Differences Between AGM And Flooded Deep-Cycle Batteries

When it comes to powering electric vehicles like golf carts, deep-cycle lead-acid batteries are the industry standard. The reason is that they are designed to provide the most cost-effective energy storage and delivery over the life of the battery.

Over the years, there have been two main types of deep-cycle lead-acid batteries that many golf car owners and fleets have used, the Flooded Lead-Acid (FLA) battery and the Absorbed Glass Mat (AGM) battery. While both provide optimum performance in a wide variety of applications, their design difference can offer various advantages depending on the application.

Engineering

The main design difference between FLA and AGM batteries is how the electrolyte is managed. In FLA batteries, the battery plates are submerged in the liquid electrolyte. During use, water in the electrolyte is broken down into oxygen and hydrogen gases and water is lost. This requires regular additions of water to be replaced to keep the battery plates fully submerged in the electrolyte.

In AGM batteries, the electrolyte is absorbed in special glass mat separators that retain all the electrolyte needed for the life of the battery.  Since there is no free electrolyte, the oxygen generated on a charge is recombined at the negative plate.  In normal operation, hydrogen is not generated and no water is lost.  This eliminates the need to add water and also allows the battery to be sealed with a one-way valve that prevents leakage of the electrolyte.

Performance Differences

FLA batteries have been used in a wide variety of applications for well over 150 years. Their popularity comes from their safety, reliability, and cost-effectiveness when compared with other types of rechargeable batteries.   According to Fred Wehmeyer, U.S. Battery Senior VP of Engineering, FLA batteries deliver the lowest cost per watt-hour both in acquisition cost and in overall cost per charge/discharge cycle.  “This is why they are the best choice for fleets of vehicles or equipment that are used heavily on a daily basis,” says Wehmeyer. “Also, both FLA and AGM batteries offer an environmental advantage over other types of batteries because they are essentially 100 percent recyclable and enjoy the highest recycling rate of any commercial product.”

AGM batteries offer the advantage of being maintenance-free. This can be significant in applications where regular maintenance is difficult or costly, such as when the batteries are located in remote or hard to access locations. Even though AGM batteries cost more per watt-hour, the elimination of maintenance costs reduces the overall battery operational costs.  Also, since the battery is sealed and does not emit gases in normal use, it can be used in sensitive areas such as food or pharmaceutical storage facilities.

Selecting between FLA or AGM deep cycle batteries ultimately depends on the type of use and the capability to provide regular maintenance in the application.

AGM = No Maintenance + Higher Cost + Susceptible to abuse like overcharging

FLA = Requires Watering + Lower Cost + Susceptible to abuse from poor maintenance

No matter what type of battery you use, it is always best to target the depth of discharge to 50 percent or less for both FLA or AGM battery types. This will optimize battery life cycle cost vs acquisition cost over the life of the battery system.

Deep-Cycle Battery Tune-Up Tips

Aside from routinely adding water and charging your deep-cycle batteries, battery manufacturers recommend giving your batteries a tune-up. Simply put, this consists of a few methods to check the condition of the deep-cycle batteries and the associated components so that everything can continue to run perfectly.

Battery Terminals and Wires

1) Safety first. Always perform battery maintenance in a well ventilated area and wear eye protection and gloves.

2) Open the battery compartment of your deep-cycle battery-powered vehicle and check the wires and terminals connected to the battery. If corroded, clean them with a mixture of baking soda and water to neutralize acid corrosion (easily done with a spray bottle). Remove the cables from the battery terminals and, using a wire brush with a plastic or wooden handle to prevent shorting, clean the terminals and wire connections down to the bright metal. Replace any wires that are frayed or broken.

3) Reconnect the cables to the battery terminals. The recommended terminal torque is 100-inch pounds or 15-18 pounds on the end of a six-inch wrench. Avoid using larger wrenches or power tools.  Lead terminals can easily be damaged by over-tightening.  The goal is to fully compress the split-ring lock washer but no more. Use insulated tools to prevent arching.

4) Once the terminals and cables are clean and connections are secure, use silicone spray or a corrosion inhibitor to prevent additional corrosion from forming.

Condition of the Batteries

1) Remove the vent caps on each of the deep-cycle batteries and check the electrolyte level in each cell. If some are low, refill with distilled water so that the plates are covered with at least ¼ inch of electrolyte before charging.  After charging top up to within a ¼ inch of split-ring level indicator.

2) Use a hydrometer to determine the state of charge for each battery. During winter storage, all of the batteries should have been stored in a fully charged state. Check the battery manufacturer’s recommendation for the fully charged specific gravity for each type of battery.

3) If the batteries are fully charged, the vehicle is ready to start service. If the batteries are not fully charged, connect the charger and let it run through a full charge cycle. After charging recheck the electrolyte level and use a hydrometer to verify the batteries are at full charge.

4) After the first 30-days of use, perform an equalization charge to balance the cells and to mix the electrolyte to  prevent stratification.

Once you’ve completed these steps, your deep-cycle batteries in your golf cart, aerial work platform, forklift or even your RV and boat, should be ready to go back to work. With regular maintenance, they will continue to run at optimum performance and last longer with lower annual operating costs.

Consistent Battery Maintenance Is Key To Longevity And Performance

There’s something to be said about due diligence, especially when it comes to your golf car’s batteries. While many individuals and golf courses are content with simply charging batteries overnight, and checking water levels whenever they get around to it, others conform to a strict maintenance schedule that ultimately prevents numerous conditions that can lead to poor performance and ultimately, battery failure.

Run It Till It Dies

The downtime while your batteries are charging is often inconvenient and some golf car owners run the car until it’s nearly out of power or dead altogether. Batteries that experience frequent deep discharges (discharges of more than 50-percent of a battery’s rated capacity) will have dramatically shorter life than batteries with lower depth of discharge (DOD). The use of ‘opportunity charging’ or charging at every opportunity instead of waiting to recharge until batteries are fully discharged will dramatically increase battery life. (This should not take the place of fully charging regularly.)  If you need longer runtime between charges, consider switching to batteries with higher amp-hour capacity.  This may require switching to a different type of battery with a lower voltage per monoblock but higher capacity.

For example, a golf car with a 48-volt battery pack can use four 12-volt batteries, six 8-volt batteries or eight 6-volt batteries (if space is available).  While all provide the same 48-volt pack voltage, the eight 6-volt batteries provide the highest capacity and runtime. According to Fred Wehmeyer, Senior VP of Engineering at U.S. Battery Manufacturing, a battery that is routinely discharged to 40% DOD will last about 2.2 times longer than a battery that is discharged to 80% DOD. The initial cost for eight 6-volt batteries is higher than four 12-volt batteries; but considering how much longer they will last, the return on investment is much greater.

Water Whenever

Failing to consistently check water levels and add water to your batteries can also result in low capacity and eventual battery failure if left unchecked. Watering flooded lead-acid batteries is one of the most basic and important maintenance procedures. During battery charging, gases evolved from the decomposition of water results in water loss. This lost water must be replaced by regular water addition.  The rate of water loss can be even higher at elevated temperature and water levels must be checked more frequently. If water is not replaced regularly, the tops of the battery plates in each cell can become exposed to air and damaged to the point that capacity is reduced and battery life is shortened.  Electrolyte levels should always be maintained above the top of the plates by adding water before charging and after charging to about 1/8-inch below the bottom of the vent wells.  Final watering should be done after charging to prevent electrolyte overflow.

If you really hate watering batteries, consider a Single Point Watering System and a battery watering monitor. These often come in kits that are pre-made for specific golf cars and/or battery packs. Monitors such as U.S. Battery’s Sense Smart Valve works with SPWS systems and indicates via a dash or battery mounted LED when the batteries need water.

Summer’s Over; Park It Till Next Year

Improper battery storage is, unfortunately,  a common practice with resorts and RV owners. Storing your golf car with the battery pack in a discharged condition for a long period of time can lead to sulfation (a condition that leads to the development of large lead sulfate crystals that reduce the battery’s available capacity). Over time, this sulfation can reduce both the full charge capacity and overall life of the battery.

The battery pack should always be fully charged before the vehicle is put into long-term storage. In winter months, this also prevents the batteries from freezing. Maintaining the batteries at full charge will keep your batteries in good condition until the next time you use them.

The Electric Golf Car Market Expected To Expand

Market Researchers See Continued Growth On Electric, Battery Powered Golf Cars Through 2026

According to a market analysis by consulting and marketing research firm, Future Market Insights, the golf car market is expected to be positive for the long-term, with electric golf cars having the highest anticipated compound annual growth rate of 6.4 percent through 2026. (Global Industry Analysis and Opportunity Assessment 2016-2026 ).

According to the research, the growth is due to the electric golf car as internal transportation for developing countries, as well as private clubs, golf-centric real estate developments, the travel tourism industry which is expected to include new construction of resorts and golf courses.

Golf Car Options Magazine also published the research, but they suspect that this expected growth of the global golf car market will be challenged with the maintenance of lead-acid batteries, claiming that they are also less efficient and require frequent charging. While battery maintenance is essential for optimum performance in electric golf cars, items such as single point watering systems, Sense Smart Valves and proper charging techniques, can dramatically reduce maintenance and extend battery life. In addition, flooded lead-acid batteries have the benefit of being recycled at a rate of 99 percent, with the recycled lead going back into new golf car batteries in a closed-loop system.

The report goes on to say that electric powered golf cars are expected to continue to dominate the market in terms of value over the forecast period.

U.S. Battery’s 12VRX XC2

US Battery’s 12VRX XC2 is a popular choice for 12-volt deep cycle batteries used in a variety of applications. Originally designed for the 48-volt EZGO RXV vehicles without watering systems, the 12VRX has become popular in many other 48-volt and 72-volt golf cars in addition to equipment in applications such as aerial work platforms, recreational vehicles, and floor cleaning machines.

US Battery developed the 12VRX as a substitute to the popular 12VXC battery in order to address the difficulty of manually watering the rear battery on RXV golf cars. The cell vents on the 12VRX are configured horizontally on the battery as opposed to the chevron or “V” shaped spacing of the 12VXC. This allows the battery to be manually watered in equipment where space is limited or where batteries are partially covered. In addition to being easier to water, the 12VRX also differs from the 12VXC in how it is lifted. The 12VRX contains lifting tabs on top of the battery that eliminates the need for the handles located on the ends of the 12VXC. This saves almost a full inch in length, allowing the 12VRX to be installed in tight compartments where the 12VXC does not fit.

While the 12VRX is only compatible with Battery Watering Technologies (BWT) watering systems, the 12VXC is compatible with both Flowrite and BWT watering systems. For RXV golf cars with existing watering systems, US Battery offers a third 12-volt deep cycle battery called the 12VXZ. This battery is designed to fit in the RXV vehicles and still be compatible with the OEM Flowrite watering kits. Of all three batteries, the 12VRX is the most universal in regards to fitment.

U.S. Battery’s 12VRX offers unique advantages for a variety of applications. Advantages include providing high capacity (155 Amp Hours at the 20-hour rate), the ability to reach peak capacity in fewer cycles than other batteries in its class, and the ability to provide the most total energy throughout the life of the battery. This premium battery is part of the company’s Endurance Plus™ line of batteries, designed to provide high value and optimum performance. U.S. Battery products are manufactured and assembled by hand in the U.S.A. See U.S. Battery’s full line of 12-volt deep cycle batteries here https://usbattery.com/products/12-volt-batteries/
