Removing a Car Battery

To remove the car battery;

  • First, locate where your car battery is positioned. You can check your vehicle’s manual if you are not sure.

  • Use the wrench to loosen the bolt or nut that secures the negative terminal and cable to the negative battery post.
  • First remove the cable and terminal from the negative battery post using the terminal puller, before doing the same with the positive terminal.
  • Remove the clamp holding battery in place. Take care not to misplace the parts and fasteners.
