Locate the Battery
The first step is to locate the battery in your vehicle. This is usually found in the engine compartment, but the exact location may vary depending on the make and model of your car. Consult your owner’s manual or look for a label on the battery to determine its location.
Important: Make sure the engine is turned off and the parking brake is engaged before attempting to access the battery.

Caution: Be careful not to touch any metal parts with the wrench or pliers, as this can cause a short circuit.
Disconnect the Positive (Red) Cable
Now, disconnect the positive (red) cable from the battery. This cable is usually marked with a positive (+) sign or a color code. Loosen the bolt on the cable clamp and pull the cable off the battery post.
Caution: Be careful not to touch any metal parts with the wrench or pliers, as this can cause a short circuit.
