Step-by-Step Battery Replacement

  1. Prepare Your Vehicle: Ensure the car is turned off and parked safely. Open the hood and locate the battery.
  2. Disconnect the Negative Terminal: Using a socket wrench, loosen the nut on the negative (-) terminal and remove the cable first to prevent electrical shorts.
  3. Disconnect the Positive Terminal: Loosen the nut on the positive (+) terminal and remove the cable.
  4. Remove the Battery Hold-Down: Unscrew any clamps or brackets holding the battery in place.
  5. Remove the Old Battery: Carefully lift the battery out, keeping it upright to avoid spills.
  6. Install the New Battery: Place the new battery in the tray, secure it with the hold-down clamps, and reconnect the terminals—positive first, then negative.
