• Disconnect the negative terminal first, then the positive terminal.
• Do not let a wrench touch both battery terminals or any metal body part at the same time.
• If the battery has corrosion, clean it carefully and avoid breathing dust from the terminals.
• No battery disconnect is required before starting beyond removing the cables from the battery itself.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the battery

• Open the hood and find the battery in the engine compartment.
• Look for the large rectangular battery and the hold-down clamp.
• Take a quick photo first.

Step 2: Disconnect the negative cable

• Use a 10mm socket and 1/4-inch ratchet to loosen the negative terminal nut.
• Remove the negative cable from the battery and tuck it aside so it cannot spring back.

Step 3: Disconnect the positive cable

• Use a 10mm socket and 1/4-inch ratchet to loosen the positive terminal nut.
• Remove the positive cable and keep it from touching metal.

Step 4: Remove the battery hold-down

• Use a 10mm socket to remove the battery hold-down clamp or bracket.
• Set the hardware aside in a safe place.

Step 5: Lift out the old battery

• Use a battery strap or lift handle to lift the battery straight up.
• Batteries are heavy, so lift with both hands and keep your back straight.

Step 6: Clean the tray and terminals

• Use a wire brush and battery terminal cleaner brush to remove corrosion from the cable ends and battery tray.
• Wipe away loose dirt and dry the area.
• Clean metal means better power flow.

Step 7: Install the new battery

• Set the new battery into the tray in the same direction as the old one.
• Make sure the terminals match the cable reach without stretching.

Step 8: Reinstall the hold-down

• Use a 10mm socket to reinstall the hold-down clamp or bracket.
• Tighten snugly; do not overtighten and crack the battery case.

Step 9: Reconnect the positive cable

• Install the positive cable first.
• Use a 10mm socket to tighten the terminal nut until secure.

Step 10: Reconnect the negative cable

• Install the negative cable last.
• Use a 10mm socket to tighten the terminal nut until secure.
• Positive first, negative last.

Step 11: Protect the terminals

• Apply battery terminal protectant to help slow future corrosion.
• Check that both cable ends are fully seated and cannot twist by hand.
