Step‑by‑Step Battery Replacement

Step 1: Prepare the vehicle

  • Park on a flat surface and engage the parking brake
  • Turn off ignition and remove the key
  • Disconnect any accessories
  • Wear gloves and safety glasses

Step 2: Locate and inspect the battery

  • Open the hood and find the battery housing
  • Check for cracks, leaks or severe corrosion
  • Note the battery orientation (positive vs negative)

Step 3: Disconnect the old battery

  • Loosen the negative (‑) terminal with an 8 mm wrench
  • Remove the negative clamp first and set aside
  • Loosen the positive (+) terminal and remove it
  • If a hold‑down bracket is present, remove it with a socket

Step 4: Clean the tray and terminals

  • Spray a baking soda solution on any corrosion
  • Scrub with a terminal brush or rag
  • Dry the area completely

Step 5: Install the new battery

  • Place the new battery in the tray matching the original orientation
  • Re‑attach the hold‑down bracket and tighten securely
  • Connect the positive (+) terminal first and tighten
  • Connect the negative (‑) terminal last and tighten  
  • Verify all connections are tight

Step 6: Test the installation

  • Start the engine; it should turn over smoothly
  • Check the voltage with a multimeter (should read 12.6 V idle)
  • Reset any electronic memory if needed
  • Close the hood

Common Mistakes

  • Connecting positive terminal before negative
  • Forgetting to remove hold‑down bracket
  • Not cleaning corrosion which can cause poor start
  • Lifting the battery without proper stance leading to injury
