Visit U.S. Battery at the ISSA/Interclean 2016 Trade Show Booth #442

 

Corona, CA – U.S. Battery is attending the International Sanitary Supply Association (ISSA/INTERCLEAN) show in Chicago, IL October 26th-28th. Attendees are invited to visit U.S Battery’s booth #442 to learn how U.S. Battery deep-cycle flooded lead-acid , and AGM batteries can help exceed performance capabilities in commercial floor cleaning applications.

The ISSA/INTERCLEAN Show allows U.S. Battery to meet with, and provide support for national and global representatives within the cleaning industry. The company’s products are available in both six and twelve -volt configurations, and feature extra heavy duty connector lugs, a durable polypropylene exterior case, and the company’s  SpeedCap® positive locking venting system for easy maintenance.

Using Runtime Ratings To Compare Golf Car Batteries

 

When it comes time to purchase a new set of batteries for your golf car or complete fleet, it makes sense to compare products and shop for the best value.  Because there are so many batteries available for a single type of vehicle, it’s important to make sure you’re comparing batteries with the same internal construction (Flooded vs AGM vs Gel), voltage output, and capacity ratings.  This is where it can get confusing for many golf car owners and fleet managers.

The information on the labels can sometimes be confusing as manufacturers don’t always list the same testing criteria, making comparisons difficult. An example of this is when trying to compare two similar batteries that show different battery cycle life ratings. Battery cycle life ratings are often based on selective data from the manufacturer.

Comparing Depth Of Discharge

Typically, cycle life ratings are determined based on the depth of discharge (DOD), the percentage of amp-hour (AH) capacity discharged from the battery on each discharge. Most battery manufacturers recommend a 50 percent DOD for optimum cycle life vs runtime. The problem is that cycle life can be quoted at a wide variety of DOD ratings which can result in what appears to show a longer cycle life for one battery type over another. This makes for a comparison that is not accurate. When comparing cycle life ratings, make sure they are rated using the same DOD.

Comparing Amp-Hour Ratings

Amp-hour ratings are often used to compare similar lead-acid batteries and can also be misleading. As an example, a 6-volt battery may list its amp-hour (Ah) rating as 200 Ah at the “20hr rate”. This means that the battery will provide 10 amps of current for 20 hours until the battery is fully discharged or “spent”.  A common mistake is assuming that a battery with a 200 amp-hour rating will provide 200 Ah at all discharge rates. Enter Peukert’s law. This states that battery capacity decreases as the rate of discharge increases.  If the same 200 Ah battery is fully discharged at a higher rate over five hours, the battery will deliver only about 150 Ah at 30 amps.  Also, the relationship between battery capacity and the rate of discharge is not linear, so it is important to find the rated capacity at the discharge rate for the application in which you plan to use the battery.  Most battery manufacturers publish tables of ratings vs discharge rate or discharge time for each battery type.

Look At Runtime Ratings

Even though manufacturers list various amp-hour ratings, it’s often difficult to know which ones to use in order to make the right comparison for your application. It may be more accurate to use the runtime ratings in minutes that can typically be found on the battery manufacturer’s spec sheets and websites.  As an example, U.S. Battery publishes ratings that show how many minutes a battery can provide at 25, 56, and 75 amp-draws. By comparing the rated runtime in minutes, you’ll get a better idea of the performance you can expect when comparing two similar batteries. These runtime ratings are based on the actual discharge currents seen in typical applications and may be more applicable than the amp-hour ratings. For example, RV and marine discharge rates usually fall into the 25 amp range while most golf car discharge rates fall into the 56–75 amp range (56 amps for 48-volt cars and 75 amps for 36-volt cars).

Key things to remember when comparing batteries:

  1. Cycle life comparisons should be made at the same depth of discharge (DOD).
  2. Amp-hour ratings should be compared using the same discharge time and/or discharge current that will be used in the application.
  3. Run-time ratings may be the most accurate comparisons when selecting a battery for a given application.

Dutt Electronics Found U.S. Battery Products Provided Optimum Performance For Its New Energy Save OE Power System

Dutt Electronics, a manufacturer of alternate energy inverters for the OE market, found that U.S. Battery products were the best choice for energy storage for its new Energy Save power system, which has been nominated for the 2016 EnerTIC Award in the category of Smart Industry.

“We conducted a detailed study of existing storage technologies,” said Ramon Ugarte of Dutt Electronics. “Our Energy Save application required a mature technology and low cost. Initially, Lithium-Ion batteries would have worked, but for a quick return on investment and low cost for our customers, deep-cycle flooded lead-acid batteries were the best choice.”

The Save Energy system uses 36 U.S. Battery 185E batteries with XC2™ formulation and Diamond Plate Technology® which deliver more watt-hours per liter and watt-hours per kilogram than any other flooded lead-acid battery on the market. “There are plenty of battery brands available,” said Ugarte. “But we wanted to use U.S. Battery products because their technical characteristics were the best fit, and they offer the support of a solid company with more than 90-years of history.”

The Dutt Energy Save system is an integrated unit that combines a bi-directional inverter, monitoring system, and battery pack all in one unit. With autonomous operation, it balances power output between stored energy consumption and battery charging during peak energy hours to reduce overall energy costs.
