Battery Impedance Tester Battery Impedance Testers read and record Voltage, Internal Resistance, Capacitance, and Temperature of all types of batteries. Measuring of a battery cells internal resistance value and comparison to a reference value of the cell when it was new has become the newest diagnostic trend in detecting a problem with a battery cell long before it fails. Data Storage and logging features capture data for incorporation into reports that can be transmitted and stored electronically.
New generation diagnostic testers give on screen Pass/Warning/Fail indication at the time of testing allowing further investigation of potential problems while still on site and eliminating return trips to remote locations to figure out what is wrong later on.
