Measure battery with multimeter.

The multimeter’s leads are connected to the battery to measure the DC voltage across it and decide whether it is good, dead, or produces an intermediate voltage. Connect the red probe to the VΩmA socket and the black probe to the COM socket on the multimeter for voltage, resistance, and continuity measurements, as seen in Figure 2.To measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below).Step 1: Set Multimeter.
