The only way to know your stationary batteries will perform to specification is to test them regularly.

NERC standard PRC-005-2 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 SBS constant current load banks are an affordable way to perform easy and accurate 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 also does not have to constantly adjust the current during the test like many other load banks.

These 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.
