Follow these steps carefully to disconnect the battery without causing damage to your vehicle or yourself.
Identify Battery Terminals
The battery has two terminals: positive and negative. Each terminal connects to a different cable. The positive terminal usually has a red cover or a plus sign (+). The negative terminal is often black and marked with a minus sign (−).
Knowing which terminal is which helps avoid mistakes during disconnection. Always disconnect the negative terminal first to reduce risk.
Remove Negative Cable
