What is conductance?

Conductance in batteries explained

What is conductance?

Conductance is a measurement of the batteries ability to produce current. To measure conductance the tester creates a small signal that is sent through the battery then measures a portion of the AC current response. Conductance is the measure of the plate surface available in the battery which determines how much power the battery can supply. As a battery ages the plate surface can sulfate or shed active material which adversely affects its ability to perform. In addition, conductance can be used to detect cell defects, shorts and open circuits which will reduce the ability of the battery to deliver current. Using conductance Midtronics testers are able to determine the battery’s true state of health.

Why use conductance when testing a battery?

  • No discharge of the battery during the test
  • Ability to test discharged batteries without the need to charge a battery first
  • Quick, simple and repeatable tests.
  • Safe testing in the vehicle without any risk of damaging in0-board systems.
  • Portable and light-weight testing.
