battery internal resistance tester
A battery internal resistance tester (also known as a battery internal resistance detector, battery tester, or battery tester) is a professional battery diagnostic device that uses advanced AC discharge testing technology to accurately measure the voltage and internal resistance across a battery. This measurement data allows a comprehensive analysis of the battery's capacity degradation, internal impedance changes, and technical performance, accurately assessing the battery's health and remaining service life, providing a scientific basis for preventive maintenance and operational management.
