Article: If you're unsure about which part is the battery, then check your owner’s manual. Some vehicles have their battery in the trunk, under or behind an access panel. If the post is not covered, place a towel or other clean rag over the positive post. This will help you to avoid accidentally creating sparks by coming into contact with the positive terminal. The nut will be located to the left of the terminal. If needed, pry the terminal open with a screwdriver, or gently wiggle the connector until it loosens. Loosen the nut that holds the terminal onto the positive post by using a socket wrench. Although the negative terminal has been removed, still be careful to ensure the wrench used does not contact any other metal. If needed, pry the terminal open with a screwdriver or wiggle the connector to loosen the terminal.
