What is the principle of measuring voltage in battery cabinet

Voltage measurement: The battery tester uses an internal voltage measurement circuit to measure the voltage of the battery. To measure the direct current (DC) voltage, the DMM must be set to the DC voltage function, typically marked with a 'V' and a straight line. . Well, it is the electrical potential difference between the two (positive and negative) terminals of the battery. In other words, the electrical force. . By measuring the voltage of the battery and the current flowing through the battery, the battery tester can calculate the internal resistance of the battery.
