Customer ServiceCross-Sectional Area: If the cross-section of a material is large, it can allow more current to pass through it. Similarly, a thin cross-section restricts current flow. Length of the Conductor: A short conductor allows current to flow at a higher rate than a long conductor. It''s a bit like trying to move a lot of people through a hallway.
Customer ServiceConductivity meters, which use a battery as their power source, provide an AC voltage to their sensor electrodes by converting DC to AC. Let us consider resistance R (Ω) once again. As might be expected from the river analogy, resistance R is proportional to the length of the conductor—such as an electric wire—and inversely proportional to its cross-sectional area.

Battery conductance is measured by evaluating the voltage response to a small, select frequency AC current signal briefly impressed on the battery. The resultant conductance measurement provides pertinent battery information without the need of bringing the battery to full discharge.
The resultant conductance measurement provides pertinent battery information without the need of bringing the battery to full discharge. As a battery discharges, its conductance and capacity are reduced with a simultaneous drop in power in a predictable manner due to the depletion of conductive active materials.
Initial conductance value for the most batteries can be provided by the battery manufacturer. If the batteries conductance value is not available it can be reasonably established by using the average of 20 to 30 measured conductance values provided they are the same type of battery, date code and state of charge.
If the batteries conductance value is not available it can be reasonably established by using the average of 20 to 30 measured conductance values provided they are the same type of battery, date code and state of charge. Measure and record the initial conductance value after battery installation and with one to six months of float service.
The resistance and conductance of a battery are two parameters used to determine the health of battery strings and identify failed cells.
Conductance test measurements can reliably track and predict the rate of battery degradation. Battery capacity (rated ampere hours) is the ability of the battery to deliver a given current for a given period of time (Ah = I x t). At present, the only way to determine a battery’s actual capacity is by performing a true long duration load test.
