Replacement Batteries For Nilfisk Floor Cleaning Machines

Choosing the right deep-cycle batteries for Nilfisk Retriever and SRModel Ride-On-Top floor cleaning machines

Nilfisk is one of the leading manufacturers of battery-powered floor cleaning machines that last a long time. Many older models are still in use with maintenance crews that utilize these vehicles on a full-time basis. With proper maintenance, the deep-cycle batteries can last several years but eventually will need to be replaced. Here are some of the best replacement batteries with some options for SR and Retriever sit-on-top models.

The Nilfisk Retriever 4000B and 4600B model cleaning machines, as well as the Nilfisk SR1100B machines, require a 24-Volt battery pack that fits a Group Size 902 deep-cycle battery.  U.S. Battery manufactures a US 305XC2 deep-cycle battery that is a direct replacement that provides 310 amp-hours at a 20-hour rate. If the vehicle will be under severe working conditions requiring longer operating times between charges, U.S. Battery also has a High Capacity battery for these vehicles, a US 305HCXC2, which provides 340 amp-hours at a 20-hour rate.

There are several models of the Nilfisk SR ride-on-top floor cleaning machines that require different size batteries because of the size and shape of the unit. For Nilfisk SR1000B and SR1005B models that require a 24-volt battery pack with a group size 31 battery, U.S. Battery offers it’s US 31DSXC2 deep-cycle battery that provides 130 amp-hours at a 20-hour rate.

Nilfisk SR100ECO models utilize a group size 24 battery and operate with a 12-volt system requiring two 12-volt batteries. U.S. Battery’s US 24DCXC2 is an optimum choice for a replacement with an 85 amp-hour rating at a 20-hour rate. Larger Nilfisk SR1300B models also have a 24-volt system but can operate with longer runtimes with four 6-volt batteries in the 903 group size platform. U.S. Battery’s US L16XC2 deep-cycle batteries are a popular choice, providing 385 amp-hours at a 20-hour rate. Greater capacity can be achieved with U.S. Battery’s US L16HCXC2 high-capacity batteries that are rated at 420 amp-hours at a 20-hour rate.

The Nilfisk SR1300ECO floor cleaning machine utilizes a 24-volt system requiring two 12-volt deep-cycle batteries in a group size 27. U.S. Battery’s US 27DCXC2 makes a great replacement, providing 105 amp-hours at a 20-hour rate.

Group 27 & 31 Batteries and Floor Cleaning Machines

Group 27 & 31 Batteries Designed for Floor Your Cleaning Machines

Maintaining clean facilities has become more critical than ever. To reduce the spread of the COVID-19 outbreak, reliable power for floor cleaning machines is playing an essential role in a Facility Manager’s cleaning regimen.

Many battery-operated floor cleaning. machines utilize BCI group 27 & 31 batteries. Typically, group size 27 and 31 batteries are referred to as “Hybrid.” This is due to the way they are constructed (generally designed for lighter cycling duties such as marine and RV applications). While “hybrid” type batteries are designed to have more deep cycle capability, than Starting batteries, they do not perform as well over time. “Hybrid” type batteries cannot cycle at the same performance levels and are unable to produce as many cycle lives as a true deep cycle battery.

The US Battery team, in consultation with some of our industry partners, came to the conclusion that if we were going to be a player in this market that we needed to have batteries that could provide our customers with a quality product that is also a better value. So, we set out to build a better option. We worked from the ground up and developed our “DC” line of batteries, which includes the US 27DC XC2, and the US 31DC XC2 specifically for use in high-energy consuming cleaning equipment.

When comparing to the “Hybrid” types available on the market, hybrids generally can provide approximately 150-170 cycles when discharged down to 1.75 volts per cell. Our DC line, by comparison, typically supplies about 500 cycles. This is a considerable improvement, and while slightly more expensive than a hybrid, the value to the end-user is substantially improved.

Today our DC line of batteries are used in many floor cleaning machines; because of their reliability and long life. Operators of Nilfisk, Minuteman International, and Power-Flite floor machines often find them powering their equipment.

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.

8V batteries with watering kit

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, which 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 Terminals And Cable Maintenance Tips

When battery-powered vehicles and equipment suffer from intermittent performance issues, one of the most common reasons for this is poor battery cable connections. Ironically, loose connections can be caused by both under-tightening and over-tightening of the battery terminal connectors, as well as corrosion that can occur over time. Deep-cycle battery terminals are made from lead, which is a soft metal that creeps over time. The result is that they must be retightened regularly to maintain proper torque levels. If too much torque is applied when attaching cables to battery terminals, however, it can cause damage to the lead terminals preventing them from making a proper connection.  Battery manufacturers recommend terminal torque specifications that vary with the different types of terminals used for deep-cycle batteries.

Deep cycle batteries can come with UTL, UT, large and small L, Offset S, and SAE tapered post terminals, among others.  For UTL and UT battery terminals with threaded studs, the recommended torque is 95 – 105 in-lb (7.9 – 8.8 ft-lb).  For bolt-thru terminals such as large and small L and Offset S, the recommended torque is 100-120 in-lb (8.3 – 10 ft-lb).  SAE terminals have a recommended terminal torque of 50-70 in-lb (4.2 to 5.8 ft-lb). For other terminal types, consult the battery manufacturer’s recommendations. When measuring terminal torque, use a torque wrench with settings or readings in the 0 – 200 in-lb (0 – 16 ft-lb) range. Larger torque wrenches can inadvertently exceed the recommended settings or readings.

It is also important to consult the battery manufacturer’s recommendations for the proper type and assembly of the terminal hardware. Most manufacturers provide stainless steel nuts and lock washers or plated bolts, nuts, and lock washers with the batteries depending on the type of terminal used. The correct method is to position a lock washer between the nut and the connector (never between the connector and the lead terminal) and apply the recommended torque to completely compress the lock washer without deforming the lead terminal.

Clean terminals will maintain the best connection, so if corrosion is observed on the battery terminals and connectors, they should be cleaned with a wire brush and a solution of baking soda and water to neutralize any electrolyte that may be on the surfaces. To reduce the formation of corrosion on the terminals, battery manufacturers recommend using a corrosion inhibitor after making proper connections. Never apply grease or other lubricants between the terminals and connectors since they can interfere with the connection.

Check the cables to determine if they are corroded and need to be replaced.  Corrosion can extend under the cable insulation but is often not visible. A good ‘tug’ on the cables can expose weak connections. If new cables or connectors were added during the life of the vehicle, make sure the wire connectors are properly crimped and soldered to the cable ends.  Studies have shown that wire cables with crimped connectors that are not soldered to the cable ends can corrode faster and create a high resistance connection between the wire cable and crimped connector. This high resistance can cause excessive heating during discharge and melt the lead terminal, causing a loss of connection and permanent damage to the battery.  If any of the cables show signs of melted insulation, corrosion under the insulation, or have bare wire showing replace the cables and connectors.

While faulty connections are often the cause of battery terminal meltdowns resulting in poor performance, using appropriately sized wires with properly crimped and soldered connectors and the proper torque settings will reduce the chances that poor connections will adversely affect battery performance.

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.

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/
