The battery internal resistance tester (different from the principle of multimeter resistance measurement, its measured value is in milliohm level, while the multimeter's measured value is in ohm level; and the multimeter can only measure the resistance of objects without a power source, while the internal resistance tester can measure the resistance of both objects without a power source and objects with a power source, so the two cannot be equated) uses the magnitude of the internal resistance value to judge the deterioration state of the battery. (Generally speaking) The smaller the resistance value, the better the battery performance. Therefore, using the method of measuring internal resistance to detect batteries is a good method with fast speed and high reliability.
