The SOCTESTER™ Series is exclusively offered by USEICORP

People trust the SOC
This sophisticated equipment allows the operator to exercise and explore the battery's internal profile, measure the battery's state of performance, and verify the battery's ampere-hour (AHR) rating. 

The information that the
SOCTESTER™ provides in 43 seconds has shown to be as reliable as the information provided by a standard 20 hour battery discharge test.  Compliance and maintenance testing through full discharge reduces the life of the battery under test. 

The possibility of battery damage occurring in the full discharge / recharge process is proven.  Testing with the SOCTESTER™ allows the user to remain within compliance guidelines for alternative load, eliminates the possibility of detrimental effects of full discharge / recharge to the battery under test, speeds up the testing cycle reducing time spent testing backup systems, and thus reduces labor costs while providing superior performance results.

This makes the
SOCTESTER™ perfect for testing batteries anywhere they are found, in inventory or in the field.  The SOCTESTER™ is also ideal for battery matching, wherever batteries are used in series. This allows you to optimize reliability, minimize down time, and maintain efficiency
in system operations by verifying your batteries ability to perform at any given time.

SOCTESTER™ battery analyzers were developed as fast and accurate field test instruments with the capability of determining the ability of sealed lead-acid (calcium) batteries to perform for specific periods of time.  The measurement developed determines the “True-State-of-Charge” (TSOC), by examining the battery’s internal profile characteristics.

SOCTESTER™ battery analyzers were developed to quickly and accurately determine the ability of vent regulated lead acid (VRLA) batteries to perform for specific periods of time, whether in inventory or in the field.  SOCTESTER™ battery analyzers scan the infrastructure of the battery and exercise it to measure its ampere hour capacity, its ability to supply relatively large currents, and whether it is fully charged.  SOCTESTER™ then determines the battery’s energy profile, quickly computes the battery’s characteristics, and displays the battery’s True SOC (State of Charge).  All in just 43 seconds.

Typically, systems operate at a rate lower than that of their weakest battery. Matching batteries by state of performance. manufacturer, and date manufacture assures optimum performance.  The SOCTESTER™ makes this process affordable and reliable.  More detailed information on battery matching can be found in the USEI Battery Tester Education Center or visually depicted on the SOCTESTER™ Battery Tester Demo Movie.

SOC testers are fast and accurate field test instruments used to determine the state-of-charge (battery capacity) of sealed lead-acid batteries housed in equipment or stored as inventory.  These patented instruments have been modified with the latest technology to accommodate the newer, more sophisticated batteries entering the market.

intuitive tester designWhile the SOC testers are not the first battery testers on the market, they are the only ones using an exclusive testing method that allows the operator to exercise and explore the battery’s internal profile - in less than 43 seconds - measuring the state-of-charge (SOC) and full rated capacity of the battery.  Because of this short, accurate testing period, SOC battery testers will assist an organization in reducing costs, thus increasing profit while providing ultimate reliability and safety for employees, customers and consumers alike.  Companies often overlook revenue lost due to a misunderstanding in the importance of battery maintenance.  98% of all ups systems failures are the result of faulty batteries and operator error.  Reductions in diagnostic test times, simplified operation, better inventory management and finding field faults with equipment already in service are just some of the ways SOC testers capture these lost revenues, thus ensuring a short pay-back period on the cost of the instrument. 

easy to follow testing instructionsThe expanded use of sealed lead-acid batteries in equipment such as fire/security alarms, emergency lighting and integrated security systems has given rise to the need for more accurate and faster testing methods in order to meet the regulations set up by federal, state and local government agencies regarding duration of power, storage, and transportation, such as the NFPA and other regulatory commissions.  SOC testers are designed to assist users in meeting these regulations, without the burden of increased maintenance costs or service call times.

A battery’s deterioration may be altered by many factors, but the most common causes of diminished stored energy capacity is self discharge and improper battery charging methods.  Typically, self discharge is a phenomenon where the rate increases with temperature.  Even a battery on float charge for long periods of time often deteriorates below its ability to work at full capacity.    It is essential, therefore, to periodically test batteries to determine their SOC, thus assuring required performance characteristics are intact.

simple to understand test procedureNewer type batteries require more sophisticated re-charging technology, which unless clearly understood during the product development process can result in poor operational performance of the equipment being powered.  This is significantly evident in the emergency and security equipment entering the market today. Improper re-charging contributes to battery failure, but misunderstanding of the handling of batteries contributes equally in battery failure rates.  Even the best battery made will not work properly if it is not treated correctly.

SOC testers assure the user that the battery has been tested to provide sufficient energy in emergency conditions.  These portable battery testers are ideal for all applications including field diagnostic, regulatory compliance testing, maintenance or installation and stored battery inventory management.  The SOC testers are perfectly suited for both on-site and laboratory needs and are available in their own ruggedized carrying case with the ability to test in excess of 450 batteries per internal battery charge.  The SOC140 will test 6 and 12 volt 3-140 ampere hour batteries using a 43 second test cycle furnishing an evaluation of the battery’s condition, while the SOC 255 will test up to 255 AHRs at 6 and 12 volts.  Custom voltage and AHR settings may also be available upon request.  Contact Battery tester support via email with your questions, or call 1.800.978.8058 and get a solution right now.
