How Old Or New Are Your Deep-Cycle Batteries?

Used and refurbished battery-powered equipment are abundant and are often found at great prices. Although the vehicle may be in good working order, it’s important to determine how old the deep-cycle batteries are. In most cases, battery manufacturers stamp or etch a date code on the battery indicating the month, year, and location of manufacture.

U.S. Battery uses a stamped code on the terminals of its flooded lead-acid batteries. The top left letter stamped on the terminal correlates to the month it was manufactured (A-L refers to January to December). In this example, the letter “K” is the 11th month indicating the battery was manufactured in November. The number indicates the year 2014, and the bottom letter specifies the U.S. Battery plant where it was produced.

Increasing Your RV Battery’s Capacity and Overall Runtime

On Overlanding adventures where primitive campsites don’t have power hookups, your house battery may not be large enough to provide the power you need for the length of your stay.  On these occasions, one definitely does not want to run out of power for lights, cooking, or charging mobile devices. So if you’re venturing out into areas without power to plug into, it’s easy to add more battery power and run time if you have space.

Deep-Cycle Batteries and Amp-Hour Ratings

Many RVs come with a single 12-volt battery dedicated to the unit’s house power. To increase the capacity, you first need to make sure the battery is a deep-cycle model. Some RVs are outfitted with a typical automotive starter battery which works fine to provide lots of initial power to start an engine, but not for maintaining power over several hours for lights and other electrical accessories. Switching to one 12-volt deep-cycle battery is a start. It will provide power for a longer period of time, indicated in amp-hours (usually the 20 hour capacity in Ah).

Amp-hour ratings are shown on the battery label and will help you figure out how many discharge amps the battery can provide for however many hours you need to supply.  Here’s an example. The most common rating is the 20 hour capacity in Ah or rate in amps.  The capacity in amp-hours is found by multiplying the discharge time (20 hours) by the discharge rate.  The discharge rate is found by dividing the rated amp-hour capacity by the discharge time (20 hours).  For example, a battery that is rated at 100 amp-hours at the 20-hour rate would have a continuous discharge rate of 5 amps for 20 hours.  Similarly, a battery with a rating of 100 amp-hours at the 5-hour rate would have a continuous discharge rate of 20 amps for 5 hours, but its 20-hour capacity would be much higher than 100 amp-hours (probably closer to 130 Ah at C20).  When selecting a battery for a given application, it is important to use the rating that is closest to the average runtime needed between recharges in the application.  That, combined with knowing the total amperage your electrical accessories in your RV will draw, will help to determine how much battery capacity you will need.

Two-Batteries Are Better Than One

If you switched your house power to a deep-cycle battery with a greater amp-hour rating but find you still need more capacity, you can add another battery in parallel if you have space. Adding a second deep-cycle 12-volt 100 amp-hour battery connected in parallel, for example, will keep the voltage the same at 12 volts but will increase the capacity to 200 amp-hours.  This can double the discharge rate (10 amps for 20 hours) or simply run the system for a longer time between recharges.

If you have a large enough space in your RV to add more batteries, you can add a third 12 volt – 100 Ah battery connected in parallel.  However, it is not recommended to make more than three parallel connections.  If even more capacity is needed without increasing system voltage, another method is to connect 6-volt batteries in a series/parallel circuit.  Six-volt golf car deep-cycle batteries are designed with much higher capacity per battery. (200 – 250 Ah each).

Two six-volt batteries can be connected in series for 12 volts and then another set of two connected in parallel for 400-500 Ah or a third set in parallel for 600-750 Ah at 12 volts.

The difference in wiring batteries in series and parallel can be seen here. If you plan on attempting this upgrade, make sure to use high-quality large-gauge wiring and connectors, and talk to an RV electrician for any help in setting up a multi-battery bank system. Some systems like this need to be separate from the RV’s charging and electrical system. It will also require you to use a good-quality battery charger specifically for large capacity deep-cycle batteries. If Overlanding is a long-term lifestyle, many have also considered adding solar panels to the top of their RV to keep deep-cycle house batteries charged and provide consistent power when they need it.

While upgrading to more batteries is more expensive, the larger battery bank will lower your depth of discharge (DOD) on each battery to the recommended 50% or less. This will ultimately enable the pack to last much longer than constantly draining a single battery.

Is It Cost Effective To Go Green With Lead-Acid Deep Cycle Batteries?

For many business owners making an effort to go “green” can be an expensive process, requiring investments in new equipment and infrastructure. But if a company decides to be more environmentally conscious by investing in battery-powered machines and vehicles, it may also prove to be a cost-effective choice. While switching to battery power reduces the need for plug-in electricity and combustible fuels for power, there’s also the added benefit of lower overall operating costs.

Deep-cycle lead-acid batteries are the most cost-effective form of power for these types of machinery and vehicles. According to Fred Wehmeyer, Senior VP of Engineering at U.S. Battery, lead-acid batteries provide more energy per cycle at a lower cost per kilowatt-hour than any other type of battery chemistry. That means that the use of lead batteries can translate to lower operating costs over time. It gives companies using them a greater incentive, knowing that the operating costs would absorb any up-front expenses.

In addition to lower costs, there are other environmental advantages. Perhaps the most important is that deep-cycle lead-acid batteries are a sustainable source of energy. The U.S. Environmental Protection Agency recognizes lead batteries as the most recycled consumer product in the nation. The foundation for this has been the lead-acid battery industry’s ability to create a model recycling program, one in which essentially 100 percent of them are recycled. It prevents millions of used lead-acid batteries from reaching landfills, as it is a problem currently happening with other battery chemistries.

So the question that commonly arises is, if switching to battery power is environmentally better and more cost-effective, how can various industries and rental companies make the most out of their battery-powered machines and vehicles? The answer, according to Wehmeyer, is to make sure you start with a battery that is rated for the optimum power requirements of the application and the type of cleaning machine. Selecting the correct battery further minimizes the upfront costs of going “green” in this manner and helps to extend service life for continued low operational costs.

Batteries come with various capacity ratings, so Wehmeyer recommends starting with one that matches the duty cycle of the vehicle or machinery will require. Purchasing a battery with too little capacity will shorten overall battery life and increase annual operating costs because you will have to replace them more often. On the other hand, selecting a battery with more capacity than needed will add to the initial purchase cost without necessarily increasing battery life.  Also, Wehmeyer reminds us that deep-cycle battery cycle-life ratings are not always compared using the same basis by different manufacturers.  Typically, cycle life comparisons are based on the depth of discharge (%DOD) using the C20 capacity as a baseline.

To truly take advantage of the benefits of going “green” with deep-cycle battery power, it’s also essential to perform a routine maintenance schedule. This routine should include checking water levels and filling as necessary, performing a monthly equalization charge, and minimizing the total DOD to 50 percent or less during each use. Doing these things will dramatically increase battery life and ultimately lower operational costs that will make your investment pay off in the end.

Looking at how batteries play an integral part in being environmentally friendly, it’s easy to see why many industries have continued to utilize flooded lead-acid batteries to power everything from fleets of golf cars and floor cleaning machines to aerial lifts and more. In addition to reducing annual operating costs, industries and individuals embracing battery power are also doing their part to help the economy and the environment.

Join U.S. Battery Manufacturing In Celebrating Earth Day

Join U.S. Battery Manufacturing in celebrating the 51st Earth Day. The company recognizes this day as a continued reminder of its commitment to producing environmentally responsible energy storage products. Within the battery power industry, the focus has been to develop a cost-effective means of power while also creating a sustainable source of energy. To date, this has been done on many fronts. The most successful has been the recycling rate of lead batteries. The U.S. Environmental Protection Agency continually recognizes lead batteries as the most recycled consumer product in the nation.  It is a product that delivers a sustainable energy source that powers a variety of industries such as aerial lifts and cranes, maintenance, golf car and electric vehicles, the RV and marine industries, as well as renewable energy power and backup power systems.

The recycling process means new life for old batteries. When a lead battery is recycled, virtually every part of it is broken down and reused. This process starts with the polypropylene outer case, which is broken down into small pellets to be reused for other plastic products. The lead components of the battery are melted down to make new batteries. The sulfuric acid in the battery’s electrolyte can be neutralized and purified into water or converted into sodium sulfate, a compound commonly used in laundry detergent, glass, and textiles.

With a continued push towards advancements in batteries, the future of the environment looks brighter. The investments made now into this technology will help keep the Earth safer for the future.  For more information on Earth Day or to find an Earth Day event near you, visit www.earthday.org.

Celebrating Global Recycling Day

Today, March 18th is Global Recycling day. As part of the Advancing Lead Batteries Communications Initiative (ALBCI) U.S. Battery Manufacturing and the Battery Council International urge everyone to recycle their used batteries.  The battery industry is committed to its on-going recycling efforts, which you can read more about on the BCI’s Essential Energy Everyday website.

The recycling process breaks down the outer polypropylene casings; they are then washed, melted, and extruded into small pellets. Manufacturers use these pellets to produce new battery cases as well as other plastic products. The lead oxide and lead grids of the battery’s interior are melted in a smelting furnace to form lead ingots to make new battery components. The sulfuric acid in the battery’s electrolyte is neutralized and purified into water that meets EPA clean water standards before being recirculated. The acid can also be converted into sodium sulfate during the recycling process, a compound commonly used in laundry detergent, glass, and other textiles. The process creates a sustainable energy source that is the model of recycling in the United States.
