🔋 Camry - 12V Battery Replacement

Your battery is mounted in the trunk, so this job is a little different from most cars. You’ll remove the trunk trim, disconnect the old battery, transfer any hold-down hardware, and install the new one with the correct polarity and vent setup.

Difficulty Level: Beginner | Estimated Time: 30-60 minutes

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the trunk and lift out the floor panel.
• Remove the right-side trunk trim pieces as needed using the flat trim tool.
• You should now see the battery and its hold-down bracket.

Step 2: Disconnect the negative cable

• Use the 10mm socket and 3/8-inch ratchet to loosen the negative terminal clamp.
• Lift the negative cable off the post and tuck it aside so it cannot spring back.
• Always remove the negative side first.

Step 3: Disconnect the positive cable

• Use the 10mm socket to loosen the positive terminal clamp.
• Remove the positive cable and move it away from the battery.
• If there is a fuse block attached to the battery, support it carefully while disconnecting.

Step 4: Remove the battery hold-down

• Use the 10mm socket and 3-inch extension to remove the battery hold-down bracket.
• Lift the bracket and hardware out.
• Torque on reassembly: tighten the hold-down hardware to 9 Nm (80 in-lbs).

Step 5: Lift out the old battery

• Use both hands to lift the battery straight up and out of the trunk.
• Batteries are heavy, so lift with your legs, not your back.

Step 6: Clean the tray and terminals

• Use the battery terminal brush to clean corrosion from the cable ends if needed.
• Wipe the battery tray clean before installing the new battery.
• Clean connections help prevent no-start problems.

Step 7: Install the new battery

• Place the new battery in the tray with the terminals oriented the same way as the old one.
• Make sure it sits fully flat and does not rock.
• Reinstall the hold-down bracket using the 10mm socket.
• Torque on reassembly: tighten the hold-down hardware to 9 Nm (80 in-lbs).

Step 8: Reconnect the cables

• Attach the positive cable first and tighten it with the 10mm socket.
• Attach the negative cable second and tighten it with the 10mm socket.
• Torque on reassembly: tighten terminal clamps to 5 Nm (44 in-lbs).
• Apply a small amount of battery terminal protector spray if desired.

Step 9: Reinstall trunk trim

• Put the trunk trim panels and floor panel back in place.
• Make sure nothing pinches the battery cables.
