Which Side of a Battery is Positive? A cell or battery is drawn with a long line and a shorter line. The long line is the positive side (plus is longer). The short line is the negative side (minus is shorter).
To run a test to measure voltage, you connect the red multimeter lead to the positive side of the battery or circuit that youâre testing and the black lead to the negative or ground side and set the dial to the voltage range you expect. Consider checking the voltage at the contacts of a battery pack.
