This procedure covers the removal and replacement of the 12-volt battery on a 2018-2024 Toyota Camry with the 2.5L I4 engine.

Warnings

Tools required

Parts

• 12V Battery (Group Size 35) × 1 — Group 35, 500+ CCA recommended
• Battery terminal protector spray or grease × 1 — Dielectric grease or anti-corrosion spray

Preparation

1. Ensure the vehicle is parked on level ground with the engine off and keys removed
2. Open the hood and prop it securely
3. If using a battery memory saver, connect it per manufacturer instructions before disconnecting battery
4. Locate the battery in the engine compartment on the driver's side

Procedure

1. 1

   Disconnect negative battery terminal
   Using a 10mm socket, loosen the negative (black, marked with '-') battery terminal bolt. Remove the cable from the battery post and secure it away from the battery to prevent accidental contact. Do not allow it to touch any metal surfaces.

2. 2

   Disconnect positive battery terminal
   Using a 10mm socket, loosen the positive (red, marked with '+') battery terminal bolt. Remove the cable from the battery post. Cover the terminal end with a cloth or insulating material to prevent accidental shorts.
3. 3

   Remove battery hold-down bracket
   Locate the battery hold-down bracket that secures the battery to the tray. Using a 10mm or 12mm socket (depending on your specific model year), remove the hold-down bolt. Lift the hold-down bracket off the battery and set aside.

   Remove old battery
   Carefully lift the battery straight up and out of the battery tray. Batteries are heavy (typically 30-40 lbs), so use proper lifting technique. Inspect the battery tray for corrosion or damage.
   ⚠Battery is heavy - use proper lifting technique to avoid injury
5. 5

   Clean battery tray and terminals
   Clean the battery tray with a wire brush and baking soda solution if corrosion is present. Rinse with water and dry thoroughly. Inspect and clean battery cable terminals with a battery terminal cleaner or wire brush to ensure good electrical contact.
6. 6

   Install new battery
   Place the new battery into the battery tray, ensuring it is properly seated and oriented with positive and negative terminals in the correct positions matching the cable locations. The positive terminal should be toward the front of the vehicle.
7. 7

   Install hold-down bracket
   Position the hold-down bracket over the battery and install the hold-down bolt. Tighten to specified torque. Ensure the battery is secure and does not move when pushed.

    Apply terminal protection
    Apply a thin coat of dielectric grease or battery terminal protector spray to both battery terminals to prevent corrosion.

Reassembly

1. No additional reassembly required beyond the steps above

Verification

• Verify both battery terminals are tight and do not move when twisted by hand
• Start the engine to confirm proper battery installation and electrical system function
• Check that all electrical accessories function properly (lights, radio, power windows)
• Reset the clock and radio presets as needed
• If equipped, perform power window initialization by fully opening then fully closing each window while holding the switch for 2 seconds in each position
• Check for any warning lights on the instrument cluster and address if present
