🔧 Traverse - Battery Replacement

On your Traverse, the 12V battery is in the engine compartment. Replacing it is mostly disconnecting the cables, removing the hold-down, swapping the battery, then reconnecting everything in the correct order to avoid electrical damage.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF and keep the key fob at least 10 feet away from the vehicle.
• ⚠️ Disconnect the negative (-) cable first and reconnect it last to reduce short-circuit risk.
• ⚠️ Do not let a tool touch metal while touching the positive terminal.
• ⚠️ Batteries are heavy and contain acid—wear gloves and eye protection.
• ⚠️ If your battery has a small hose attached, that’s a vent tube—do not pinch or lose it.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery in the engine compartment.
• If there’s a plastic cover/air duct in the way, remove any retainers using a trim clip tool, then remove bolts with a 10mm socket.

Step 2: Disconnect the negative (-) cable first

• Use a 10mm socket to loosen the negative terminal bolt and remove the cable from the battery.
• Push the negative cable aside so it cannot spring back onto the terminal.
• Negative off first prevents accidental shorts.
• Tighten on install: Torque to 15 Nm (11 ft-lbs)

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket to loosen the positive terminal bolt and remove the cable.
• Cover the end of the positive cable with a rag so it can’t touch metal.
• Tighten on install: Torque to 15 Nm (11 ft-lbs)

Step 4: Remove the battery hold-down

• Remove the battery hold-down bolt using a 13mm socket and 6" socket extension.
• Remove the hold-down clamp and set it aside.
• Tighten on install: Torque to 20 Nm (15 ft-lbs)

Step 5: Disconnect the vent tube (if equipped)

• If you see a small hose connected to the battery case, pull it off gently by hand.
• This is a vent tube (it routes battery fumes safely).

Step 6: Remove the old battery

• Lift the battery straight up and out using both hands (it’s heavy).
• Keep it upright to avoid any acid leakage.

Step 7: Clean and prep the terminals

• Use a battery terminal brush to clean corrosion from the cable ends.
• Install battery terminal anti-corrosion pads on the new battery posts/terminals.
• Apply a light film of dielectric grease to help reduce future corrosion.

Step 8: Install the new battery

• Place the new battery into the tray in the same orientation as the old one.
• Reconnect the vent tube if your old battery had one.

Step 9: Reinstall and tighten the hold-down

• Install the hold-down clamp and bolt using a 13mm socket.
• Final tighten using a torque wrench (5-30 ft-lbs range): Torque to 20 Nm (15 ft-lbs)

Step 10: Reconnect cables (positive first, negative last)

• Install the positive (+) cable first and tighten using a 10mm socket: Torque to 15 Nm (11 ft-lbs)
• Install the negative (-) cable last and tighten using a 10mm socket: Torque to 15 Nm (11 ft-lbs)

✅ After Repair

• Check that headlights, horn, and power liftgate work normally.
• If the clock or presets reset, re-set them from the infotainment screen.
• Drive for 10-15 minutes to allow the vehicle to stabilize charging behavior.
• If you see “Service Battery Charging System,” re-check terminal tightness and corrosion.
