⚠️ Safety & Precautions

• ⚠️ Wear eye protection and gloves—battery acid is corrosive.
• ⚠️ Turn the ignition OFF and keep the key/fob away from the car.
• ⚠️ Disconnect the negative (-) terminal first and reconnect it last to reduce short-circuit risk.
• ⚠️ Don’t let a tool touch the battery positive and any metal body part at the same time.
• ⚠️ Batteries are heavy—lift with your legs, not your back.

📋 Before You Begin

• Park your Soul on level ground, shift to Park, and set the parking brake.
• Open the hood and locate the battery (front corner of the engine bay).
• If you want to preserve settings, use a 12V memory saver (a small device that keeps power while the battery is out). If you don’t have one, it’s okay—you’ll just reset the clock and some preferences afterward.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Power down and access the battery

• Make sure the ignition is OFF and all lights are OFF.
• Open the hood and visually confirm which battery post is negative (-) (usually black cable) and which is positive (+) (usually under a red cover).

Step 2: Disconnect the negative (-) terminal

• Use a 10mm socket (or 10mm wrench) to loosen the negative terminal clamp nut.
• Twist the clamp gently and lift it off the battery post, then tuck the cable to the side so it cannot spring back.
• Negative off first prevents accidental shorts.
• When reinstalling later: Torque to 5.9 Nm (52 in-lbs)

Step 3: Disconnect the positive (+) terminal

• If there’s a cover, open it by hand.
• Use a 10mm socket to loosen the positive terminal clamp nut.
• Lift the clamp off the battery post and move it safely aside.
• When reinstalling later: Torque to 5.9 Nm (52 in-lbs)

Step 4: Remove the battery hold-down

• Locate the battery hold-down at the base of the battery.
• Use a 12mm socket, 3/8" ratchet, and 6" extension to remove the hold-down bolt(s) and bracket.
• Set the bracket and bolt(s) aside where they won’t get lost.
• When reinstalling later: Torque to 9.8 Nm (87 in-lbs)

Step 5: Remove the old battery

• Lift the battery straight up and out. Keep it level to avoid any seepage.
• Place it on the ground (not on carpet or inside the cabin).

Step 6: Clean the terminals and tray

• Use a battery terminal brush to clean the inside of both cable clamps until shiny metal is visible.
• Wipe the battery tray area with shop rags.
• Install battery terminal felt washers (if included) onto the posts when the new battery is in place.

Step 7: Install the new battery

• Set the new battery into the tray in the same orientation as the old one (positive and negative on the correct sides).
• Reinstall the hold-down bracket using the 12mm socket, then torque to 9.8 Nm (87 in-lbs).

Step 8: Reconnect terminals (positive first, negative last)

• Reconnect the positive (+) clamp first using the 10mm socket, then torque to 5.9 Nm (52 in-lbs).
• Reconnect the negative (-) clamp last using the 10mm socket, then torque to 5.9 Nm (52 in-lbs).
• Apply battery terminal anti-corrosion spray to help prevent future corrosion.

✅ After Repair

• Start your Soul and confirm it cranks strongly and runs normally.
• Set the clock and re-save radio presets if they were lost.
• If the idle seems rough at first, let it idle for 5 minutes with all accessories OFF, then drive normally for a short trip.
• Check that the battery is secure (it should not move by hand).
