🔧 Traverse - 12V Battery Replacement

You’ll remove the old 12V battery from the engine bay, transfer any insulators/vent parts, and install the new battery with clean, tight connections. A weak battery can cause slow cranking, warning lights, and random electrical glitches.

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

Assumption: Your Traverse uses a standard under-hood battery with either top-post or GM side-post terminals (both are common); use the socket that fits your terminal bolts.

⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF, remove key/fob from vehicle, and keep it away from the SUV.
• ⚠️ Wear gloves and safety glasses; battery acid is corrosive.
• ⚠️ Always disconnect negative (-) first and reconnect it last to prevent accidental short circuits.
• ⚠️ Do not let a wrench touch the positive terminal and any metal body part at the same time.
• ⚠️ If using a “memory saver,” make sure it’s a fused unit; a memory saver is a small device that keeps radio settings while the battery is out.

📋 Before You Begin

• Park your Traverse on level ground, shift to P, and set the parking brake.
• Open the hood and let the engine bay cool if it’s hot.
• If you want to preserve radio presets, connect a memory saver per its instructions before disconnecting the battery.
• Locate the battery (engine compartment). Identify the negative (-) terminal (usually black cable) and positive (+) terminal (often has a red cover).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and find the battery in the engine bay.
• If there’s a plastic cover or intake duct in the way, remove its fasteners using a 10mm socket and 3/8" ratchet, then lift it out.

Step 2: Disconnect the negative (-) cable

• Use an 8mm socket or 10mm socket with a 3/8" ratchet to loosen the negative terminal bolt.
• Wiggle the terminal off the post. If it’s stuck, use a battery terminal puller (specialty) (a small tool that safely pushes the clamp off the post).
• Tuck the negative cable aside so it cannot spring back and touch the terminal.

Step 3: Disconnect the positive (+) cable

• Flip open/remove the red protective cap (if equipped).
• Use an 8mm socket or 10mm socket with a 3/8" ratchet to loosen the positive terminal bolt, then remove the terminal from the post.
• Position the positive cable aside so it cannot touch metal parts.

Step 4: Remove the battery hold-down

• Locate the hold-down clamp at the base of the battery.
• Use a 13mm socket, 6" extension, and 3/8" ratchet to remove the hold-down bolt and clamp.
• Set the clamp/bolt aside where they won’t get lost.

Step 5: Lift out the old battery

• Use a battery carry strap to lift the battery straight up and out. Batteries are heavy—lift with your legs, not your back.
• Inspect the tray area for corrosion or liquid residue.

Step 6: Clean the tray and terminals

• Mix a little baking soda with water to neutralize corrosion.
• Use a small wire brush and clean shop rags to clean the battery tray and nearby metal.
• Use a battery terminal brush to clean the inside of the cable clamps until the metal looks bright.
• Tip: Clean metal = better starting.

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down clamp and bolt using a 13mm socket, 6" extension, and 3/8" ratchet.
• Tighten the hold-down securely using a torque wrench: Torque to 20 Nm (15 ft-lbs).

Step 8: Reconnect the positive (+) cable first

• Install felt washers (if using) and apply a light coat of battery terminal anti-corrosion spray or grease.
• Push the positive terminal fully onto the post.
• Use an 8mm socket or 10mm socket with a torque wrench: Torque to 11 Nm (8 ft-lbs).
• Reinstall the red protective cap (if equipped).

Step 9: Reconnect the negative (-) cable last

• Push the negative terminal fully onto the post.
• Use an 8mm socket or 10mm socket with a torque wrench: Torque to 11 Nm (8 ft-lbs).

Step 10: Reinstall any covers you removed

• Reinstall any intake ducting or battery covers using a 10mm socket and 3/8" ratchet.
• Make sure no tools are left in the engine bay.

• Check that headlights, interior lights, and power locks work.
• Reset the clock and radio presets if they were lost.
