The battery can be tested at any timewithout waiting for charging, and it will not pose any safety risksto the system. Conductance testing can also be performed to meeton-site inspection or position verification requirements, includingdetecting the connection resistance values between batteries. Min:Conductivity testing technology, along with resistance andimpedance technology, belong to the Ohm testing method and are bothinternationally recognized methods for testing individualbatteries. There is not much difference between these testingmethods when testing smaller capacity batteries, but when testinglarger capacity batteries, the conductivity testing method has agreater advantage over the internal resistance method, which canquickly and accurately test and detect failed batteries and triggeralarms. Because the internal resistance value of a large capacitybattery is already very small, the rate of change in its internalresistance is extremely small when the battery capacity decays. Itis difficult for the collector to detect this change, but itsconductivity value is in kiloohms (the reciprocal of ohms) orSiemens. When the capacity decays, the change in its conductivityvalue is significant and easy to detect. Therefore, conductivitytesting technology is more sensitive.
