This is important because if a lithium battery''s voltage gets too low, it can damage the battery and cause it to fail. Here''s how you can check the voltage of a lithium battery with a multimeter: 1. Set your multimeter to the "DC Voltage" setting. 2. Connect the red lead from your multimeter to the positive terminal of your lithium battery.
