LR44 battery negative(left) and positive(right)  terminals

You can distinguish the positive and negative poles of the LR44 battery by looking at the identification mark on the battery, observing the shape and color of the battery, and testing with a multimeter.

  • Look for the identification mark on the battery: Typically, the positive terminal of a battery will be marked with a "+" symbol and the negative terminal with a "-" symbol, or with "POS" and "NEG."

  • Observe the shape and color of the battery: In many coin batteries, the positive electrode is usually on the flat, smooth side, while the negative electrode is on the other side of the battery. Some batteries have a red, orange or black positive terminal and a blue, green or white negative terminal.

  • Test using a multimeter: Connect the positive and negative terminals of the multimeter to the two terminals of the battery. If the multimeter shows positive voltage, the terminal connected to the positive terminal is the positive terminal of the battery.
