The batteries will gradually age over time after being made. As the battery electrode plate surface age and produces sulfides, the batteries can not undergo the chemical reactions effectively, this is the main reason the most batteries cannot continue to be used. At this time, the internal resistance of the batteries increases. The older batteries, the greater the internal resistance. By accurately measuring the value of internal resistance, you can determine the aged of the batteries. Currently, conductance method is the most advanced method to measure the internal resistance of the batteries.2. It has a proven result of electric conductance testand 1/2 CCA discharging measurement test can be identical. Given result fully shows the accuracy of this tester. During operation, avoiding large current to discharge the battery can protect the battery from possible damages and heat generation. This allow the machine operator perform tests several times within a short time period. In recent years, the conductance method to measure the internal resistance of a battery is being widely used around the
