When Disconnecting a Car Battery, Should You Remove the Positive or Negative Terminal First?

[JulianDella]

When disconnecting the battery cables, it is essential to remove the negative terminal first before the positive one. The negative terminal of a car battery is connected to the vehicle's body, which is entirely made of metal. The moment you disconnect the negative terminal, the car's electrical circuit experiences a "short circuit," potentially damaging the battery and wiring. Below are the key points: 1. The negative terminal is connected to the car's body, and since the body is metal, the entire vehicle essentially leads back to the negative terminal. 2. Disconnecting the negative terminal instantly creates a direct connection between the positive and negative terminals, resulting in a "short circuit." This can cause significant damage to the battery and wiring.
