Load Banks

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. They display the voltage, current, and Ah removed during the test. Our 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.
