How to determine failure levels for your batteries, the internal resistance measurement level, and cut-off voltage. Also gives a quick overview on setting up the Hioki 3554 Battery HiTester to conduct tests.
Takes on-the-spot measurements of the internal resistance, voltage and temperature of lead-acid batteries, principally for UPS and similar applications, without needing to shut off the battery. Instantaneous results, on a three-rank scale of Pass, Warning, or Fail, using a composite decision based on the internal resistance and the voltage. Resolution of 1 µohm, necessary for high capacity batteries (of at least 500 Ah). Includes Hioki 9460 clip type temperature leads.
