Testing a Battery Without a Tester The internal resistance says a lot about the state of the battery. To calculate the actual internal resistance of the battery, MULTIMETER proceed as follows: • Measure the source voltage (voltage when no current is flowing) (Vo) and terminal voltage (voltage when current is flowing) (Vc). CE CAT I Calculate the voltage drop across the internal resistance OFF V 200m 20M (V, - Vo- Vc). CURRENT CLAMP 2. 2M • Measure the load current (1). Calculate the internal resistance (R = V/ I).
