SBS-2206S: Battery Capacity Tester

Constant Current DC Load Bank
250 Vdc 0–60 Amp

The only way to know your stationary batteries will perform to specification is to test the batteries’ capacity with a DC load tester.


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-2206S constant current load banks are an easy and affordable way to perform 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.


Built-in Protection:

  • Audible alarm
  • Warning on LED screen
  • High temperature shutdown
  • High voltage shutdown
  • Over load protection



  • Constant current load bank holds the current set throughout the test
  • LED screen displays real time voltage, discharge current and Ah removed
  • Units can be paralleled with the SBS-8400 if data acquisition/individual cell monitoring is required
  • Easily adjust settings electronically

3 adjustable stop points:
• End system voltage
• Discharge time
• Discharge capacity (Ah)
