Disconnect the negative battery cable first, starting with the negative terminal. Keep an eye out for a black cable and the minus (-) sign. The clamp may need to be loosened and removed with a ratchet. After the negative terminal, unplug the positive terminal. To remove the battery, unscrew the clasp. The battery can be removed from behind the hood and placed to the side. Check for any corrosion the old battery may have left behind. You should clean up any rust, dust, dirt, or other impurities you notice. To prevent inhaling dust while performing this procedure, wear gloves, wear a wire brush, and wear a mask.
