DC Load Banks / Battery Capacity Testers

Exponential Power Battery Constant Current Capacity Testers

The only way to be certain that your stationary batteries will perform to specification is to test the batteries’ capacity with a DC load bank / portable battery discharge tester.

NERC standard PRC-005 requires that Vented Lead-Acid and Nickel Cadmium systems be discharge tested every six years and Valve Regulated Lead-Acid (VRLA) batteries be tested every three years. IEEE recommends load testing stationary flooded / vented lead-acid and Ni-Cad stationary batteries every 5 years and VRLA batteries every 12-18 months.

The Exponential Power constant current load banks are an easy and affordable way to perform accurate constant current IEEE450 (Vented Lead-Acid), IEEE1106 (Ni-Cad) and IEEE1188 (VRLA) load tests. These units are quick and easy to set up. They display the voltage, current and Ah removed during the test. Since this is a constant current load bank, the user does not have to constantly adjust the current during the test, unlike many other battery load banks.

All Exponential Power Battery Test Equipment DC load banks come standard with multiple auto-stop settings and built-in protection to ensure that the batteries are never damaged due to over-discharge.

The SBS-8400, SBS-200CT, and SBS-4815 load banks have the added feature of a built-in data monitoring/acquisition system complete with wireless modules and software. The wireless modules are easy to hook up and eliminate hundreds of feet of signal wire to untangle before every use. Each module can record the real-time voltage of up to four individual cells or multi-cell blocks.
