Testing Internal Resistance of VRLA Batteries

White Paper: Benefits of Testing Internal Resistance of VRLA Batteries

Thumbnail photo of white paper covering IR testing for 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
