The only way to know if 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 (Ni-Cd) systems be discharge tested every six years and valve regulated lead acid (VRLA) batteries every three years. IEEE recommends load testing stationary flooded/vented lead acid and Ni-Cd stationary batteries every five years and VRLA batteries every 12–18 months.
The SBS-1230S constant current load banks are an easy and affordable way to perform accurate IEEE450 (Vented Lead-Acid), IEEE1106 (Ni-Cd) and IEEE1188 (VRLA) load tests.
These units are quick and easy to set up. They display the voltage, current and Ah removed from the string during the test. Since this is a constant current load bank, the user also does not have to adjust the current during the test.
These load banks come standard with multiple adjustable stop points and built-in protection to ensure that the batteries are never damaged due to over-discharge.
