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.

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/

 

 

 

Hate Watering Your Batteries? There’s An Easier Way

Single Point Watering Systems Make Watering Batteries Safe And Easy

Monitoring the level of electrolyte in your Flooded Lead Acid batteries is one of the necessary maintenance procedures to keep your batteries working properly, and extend their service life. While it sounds like a simple process, it can be very time consuming and cumbersome. Checking the water level in four or six batteries in a vehicle often requires removing the vent caps on each battery and visually inspecting the water level. In many cases, that can be difficult depending on where the batteries are located in the vehicle. If they’re difficult to reach, it can also add difficulty in adding the right amount of water, as overfilling can also cause problems, as well as not adding enough water too.

One of the ways to make the process much easier is investing in a Single Point Watering System (SPWS).  These systems allow you to add water to all of your vehicle’s batteries at one time, from a single water tube that is easily accessible. In addition, SPWS units also stop the flow of water, once it reaches the proper level within each of the battery cells. For battery powered vehicles with difficult access to the battery compartment, this makes battery maintenance much easier, and can ultimately extend the life of the batteries which can save you money in the long run.

Sense Smart ValveGoing one step further, SPWS manufacturers also have sensors available, that can be used with your watering system to monitor water levels in the battery pack and indicate when the batteries need watering. Manufacturers such as Flow-Rite and BWT have complete systems that are easy to install, and consist of valve caps that replace the factory units and allow water to be poured into each cell via a network of hoses. Most systems are also available pre-assembled for your particular application, and do-it-yourself systems are also available for custom applications.

It’s also good to point out that SPWS usually last a long time with proper care, and with constant monitoring, you’ll never need to spend too much time out of your weekend checking and watering your vehicle’s batteries again.

Battery Watering Technologies Visits U.S. Battery Manufacturing To Discuss New Designs And Continued Growth Of Single Point Watering Systems

Battery Watering Technologies, manufacturers of single point watering systems, visited U.S. Battery’s Corona, California plant to discuss the growth of its product line, and the use of SPWS in various industrial applications. Tyler Owen, Vice President Battery Watering Technologies, and Lee Pinkston, Western Regional Account Manager at Battery Watering Technologies (BWT) said that sales of SPWS in partnership with U.S. Battery Manufacturing, continues to maintain steady growth.
According to Dan Grigsby, Western States Regional Manager for U.S. Battery, the use of SWPS is increasing in a variety of industries such as golf car, aerial platform, fork-lifts, solar energy storage, and in the RV industry. “Proper watering with a SPWS can provide dramatic improvements to increase battery life, as well as reduce the time, effort, and annual costs involved in watering a fleet using FLA batteries,” said Grigsby.

Pinkston provided examples of BWT’s SPWS valves that feature internal spark arrestors, a three-piece z-lock hose-tee for added strength, and an indicator eye that allows the operator to see when the battery cell is properly filled. The company manufactures a float design unique to a variety of make and model batteries, to ensure proper electrolyte levels are reached with different battery case and cell cap designs. BWT’s gravity feed and direct flow valves that are used to water single or multiple batteries at once were also discussed, along with recommended tips for battery watering. “BWT offers a variety of fill systems that make it easy to water multiple batteries,” said Pinkston, “But there are important things to remember about watering batteries in this manner that can help prevent accidental siphoning and spills. The first is to never water before charging the battery and never leave a gravity feed system unattended. Only use only distilled or filtered water, and if you are using a direct fill system always make sure it has a pressure regulator attached to it to avoid accidental spills from over pressurizing the system.”

U.S. Battery Manufacturing has a four-year relationship with BWT and offers all of the company’s SPWS products with any of U.S. Battery’s Deep-Cycle batteries. New and exciting technology is in the works that will be available from both companies and will be announced later in the year.
