Conductance is simply known as the measurement of the plate surface leftover in the battery. The both technician are correct.
Conductance often shows the amount of power (or current) the battery can be able to supply. It is known to be able to detect cell defects, shorts, and open circuits.
An example of an electronic conductance tester is the SAT-AC Battery Conductance Tester. It is known to have a lot of functions and it is known as a portable digital data storage measurement instrument used to test battery running condition and parameters quickly and on point.
Battery conductance testers work through the act of sending a small current through the battery, and thereafter measuring its electrical resistance.
