Precautions for using lithium battery tester

Precautions for using lithium battery detectors You should know that professional lithium battery detectors are mainly used to detect current, voltage, capacity and cycle life of lithium batteries. In addition, the lithium battery detector has multiple channels for users to choose. But in the process of using the lithium battery detector, the user should know the operation precautions of the device to extend the service life of the device. So, what are the precautions for using well-known lithium battery detectors in our country? First, pay attention to the ambient temperature of the device. In the process of using lithium battery detectors, the user must be based on the same ambient temperature and The data measured under the same working battery type establishes the internal resistance reference value. In addition, the internal resistance measured by the lithium battery detector increases as the battery capacity decreases, and when the capacity is 80%, the internal resistance more than doubles. Therefore, the tested lithium battery must be fully charged. Second: Pay attention to the overheating protection of the equipment. What users may not realize is that a high-efficiency professional lithium battery detector will experience high temperatures after repeated continuous measurements on the battery. Therefore, the lithium battery detector is designed with an overheating protection device. When the temperature is too high, it is forbidden to measure the battery. However, if there is a burning smell from the inside of the instrument, and the temperature of the instrument is too high, the user should immediately stop the measurement, turn off the instrument and disconnect the clamp. Third: Pay attention to the abnormal situation of the equipment. During the process of using the lithium battery detector, if the equipment measurement is abnormal, the user should change the clamping position of the test probe and then read the result. In addition, when a large ripple occurs in the charging system of the lithium battery detector, the user can temporarily turn off the charging module and then perform a test. It should be noted that lithium battery testers are not allowed to charge, test or load frozen batteries. If the user wants to test a case, he should first thaw the battery and heat it to room temperature before testing. If the user recharges the frozen battery or tries to test it, the battery may explode and cause injury. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
