Testing Internal Resistance of VRLA Batteries

White Paper: Benefits of Testing Internal Resistance of VRLA Batteries

As battery cells age, internal resistance values in the cells increase, indicating a departure from healthy battery readings. One under-performing battery in a string can reduce the life of the other batteries, causing the entire system to fail or need replacement. Learn why regular IR testing of valve regulated lead-acid batteries can help you identify and address potential problematic cells before failures occur.

This article covers:

  • Introduction - Special testing considerations of VRLA batteries
  • Theory behind internal resistance (IR) testing and future performance
  • Maintenance how-to: establish reference readings and historical readings of IR for baseline
  • Battery analysis using IR to find potential failures
