What Color is Positive on a Car Battery?

When replacing or currently maintaining a car battery, a basic understanding of it’s infrastructure and components is essential. Knowing what color is the positive lead on a car battery is especially important. This knowledge can help minimize risks, prevent accidents, and even save lives.

Positive and Negative Terminals

A car battery can typically be broken up into two components, the positive and negative terminals. The positive terminal is typically on the right side while the negative terminal is on the left side. You can easily recognize the positive terminal due to its typically red coloring, while the negative terminal has either a black, green, or white coloring.

Before working with any car battery, it is important to always remove all the jewelry off your hands and wear the proper safety clothing and eyewear. In addition, never perform any battery maintenance while the car is running and make sure to use the proper tools. Once all these steps are done, it is time to work with the car battery.
