1. Prepare for Safety: Ensure the vehicle is turned off. Remove the keys from the ignition to avoid any electrical issues. And wear safety gloves and glasses to protect your hands and eyes from acid or debris.

  2. Locate the Battery: Open the vehicle's hood and locate the battery. Most batteries are found in the engine bay, but some vehicles have them located in the trunk or under a seat.

  3. Identify Battery Terminals: Identify the positive (+) and negative (-) terminals. The positive terminal is usually covered with a red cap or marked with a plus sign, while the negative terminal is marked with a minus sign.

  4. Disconnect the Negative Terminal: Always disconnect the negative terminal first to reduce the risk of electrical short circuits. Use the appropriate size wrench or socket to loosen the nut on the negative terminal. And once loose, remove the negative cable from the terminal and push it aside to ensure it doesn't accidentally make contact with the battery while you're working.

  5. Disconnect the Positive Terminal: After safely disconnecting the negative terminal, repeat the process with the positive terminal. Loosen the nut and detach the cable, ensuring it doesn't touch any metal parts of the car.

  6. Secure the Cables: Make sure the disconnected cables are secured away from the battery and any metal surfaces to prevent accidental electrical shorts or sparks.
