[0002] Battery maintenance and testing equipment usually uses physical contact for testing, such as DC voltmeters, internal resistance testers and capacity testers. These devices directly connect to the battery terminals to measure the battery's voltage, internal resistance and charge and discharge performance, thereby evaluating the battery's health status. A battery is a power device that can store electrical energy and release it when needed. It is widely used in various electronic devices and power storage systems.
