What is Conductance?
Conductance is a unique electrical measurement that determines the ability of a battery to transmit current through its internal structure. As such, it gives a direct relationship to battery power. Internal conductive battery components include battery grids, active material and connectors that conduct electronic current as well as sulfuric acid electrolyte that conducts ionic current between and within the plates and plate separators. Conductance is measured by probing the battery with a small AC current ripple that generates a small AC voltage response. Conductance is the relative ratio of the variation in current with the variation in voltage. It is a powerful tool for providing rapid and pertinent battery information without the need of discharging the battery with high currents that can be dangerous and leave the battery in a depleted condition. As a battery ages, its internal components gradually wear out through corrosion, disintegration and shedding. When this happens, its cond
