Eagle Eye’s SLB-Series SMART Constant Current DC Load Banks are designed for acceptance testing, discharge testing, battery capacity testing, battery maintenance, engineering examination and other testing for DC power with load. The SMART technology allows a constant current discharge without the need for manual adjustment of current during the discharge test. Our SLB-Series load banks are portable, durable, economic, safe, easy-to-use and come complete with our DataView software, providing the user with a complete data management and analysis program.

The SLB-Series has over 35 standard models allowing it to meet your system's requirements in a variety of industries. Standard DC Voltages (nominal) include: 12, 24, 36, 48, 80, 125, 240, 380, 480 VDC. Current ranges are 0-600 Amp. Two load banks can connect in parallel for a larger discharge range. Custom solutions are also available. Supported industries include utilities, telecommunications, UPS, motive power, transportation, CATV, and many more.

Eagle Eye's SMART SLB-Series come standard with monitoring of the system during discharge - as well as four (4) conditions to automatically stop the test. Optional DAC package allows the voltage of EACH CELL to be wirelessly recorded and displayed during discharge. The DAC package allows the user to evaluate the health of each cell and replace only the cells that require replacement - saving time and money by significantly reducing labor hours and replacement costs.

The included DataView software allows the user to create customized reports with company name, contact, testing location, battery manufacturer, model number, number of cells, and more. DataView reports provide the test criteria, list of weakest cells, graph of weakest cells, string information, individual cell information, time stamping, discharging graphs and an area to add notes.

Discharge testing is an essential practice for all critical backup battery preventative maintenance programs. Utility, UPS, Telecommunication, CATV/Broadband, Motive Power and other industries ALL utilize this practice to determine the true health of critical backup batteries. Load testing is the only form of battery testing that will determine the actual capacity of the battery string. Eagle Eye load banks are designed to make discharge testing convenient and easy for any application.



Load testing is a fixture in IEEE (450), (1188), (1106) and NERC (PRC-005-2) battery maintenance standards, and is critical for preventative maintenance across many industries. The financial risks that can occur due to plant downtime, personnel safety, and serious equipment damage are too severe to ignore load testing. Utilities have been load testing where preventative maintenance is required for NERC standard PRC-005-2. Every six calendar years it is required by PRC-005-2 to complete a capacity test of the battery bank for Vented Lead Acid (VLA) and NiCad batteries, and every three years for Valve-Regulated Lead-Acid (VRLA) batteries.

Load testing is increasingly popular in the motive power field to evaluate forklift batteries and to see how the batteries behave on a charge. Many forklift batteries go through an industry standard 6-hour discharge test. Eagle Eye's SLB-Series portable load banks make forklift battery testing easy and accessible.
