    usually found under the hood. It is a rectangular-shaped box with positive and negative terminals.

  3. Identify the negative terminal:

    which is marked with a “-” symbol or the letters “NEG” or “BAT -“. It is usually black in color. This terminal is connected to the car’s chassis.

  4. Carefully loosen the nut or bolt that secures:

    the negative cable to the negative terminal using a wrench or socket. Once loosened, carefully remove the cable from the terminal.

    • Be cautious not to touch any metal part of the car with the wrench or socket, as it may cause a short circuit.
    • If there is any corrosion on the terminal or cable, clean it using a wire brush before disconnecting.
  5. Next, locate the positive terminal:

    which is marked with a “+” symbol or the letters “POS” or “BAT +”. It is usually red in color. This terminal is connected to the car’s electrical system.

    • Avoid touching the positive terminal while disconnecting the negative terminal to prevent accidental electrical discharge.
  6. Repeat the same steps as before:

    loosening the nut or bolt that secures the positive cable to the positive terminal and then carefully removing the cable from the terminal.

Remember, always disconnect the negative terminal before the positive terminal to prevent any electrical mishaps. Once both cables are disconnected, you have successfully disconnected the old battery.

Now that you have completed this step, let’s move on to the next step of installing the new car battery. Keep following the instructions carefully to avoid any mistakes and ensure a successful battery replacement.
