This procedure covers the removal and replacement of the 12V battery on a 2012-2017 Toyota Camry with 2.5L I4 engine, including proper disconnection sequence and terminal torque specifications.

Warnings

Tools required

Parts

• 12V Battery × 1 — Group 35 or Group 24F, 500-600 CCA recommended
• Battery terminal protector spray (optional) × 1 — Use any dielectric grease or terminal protector

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key from vehicle
3. Note radio security code if applicable before disconnecting battery
4. Ensure all electrical accessories are turned off
5. Open hood and secure with prop rod

Procedure

1. 1

   Locate battery and identify terminals
   The battery is located in the engine compartment on the driver's side. Identify the negative terminal (marked with minus sign or BLACK cover) and positive terminal (marked with plus sign or RED cover).
2. 2

   Disconnect negative battery terminal
   Using a 10mm socket, loosen the negative (black) terminal bolt by turning counterclockwise. Do not remove the bolt completely, just loosen enough to lift the terminal off the battery post. Carefully lift the negative cable away from the battery post and position it so it cannot contact the post.
   ⚠️Always disconnect negative terminal first to prevent short circuits
3. 3

   Disconnect positive battery terminal
   Using a 10mm socket, loosen the positive (red) terminal bolt by turning counterclockwise. Lift the positive cable away from the battery post and ensure it cannot contact any metal surfaces or the negative terminal.
4. 4

   Remove battery hold-down clamp
   Locate the battery hold-down clamp at the base of the battery. Using a 10mm socket, remove the hold-down bolt completely. Remove the hold-down bracket and set aside with the bolt.

5. 5

   Remove old battery
   Carefully lift the battery straight up and out of the battery tray. Batteries are heavy (typically 35-45 lbs), so use proper lifting technique. Inspect the battery tray for corrosion or damage.
   ⚠Battery weighs approximately 35-45 pounds. Use proper lifting technique to avoid injury
6. 6

   Clean battery tray and terminals
   Inspect battery tray for corrosion. If corrosion is present, clean with a solution of baking soda and water, then rinse and dry thoroughly. Use a battery terminal cleaner or wire brush to clean both cable terminals and the contact surfaces. Ensure terminals are bright and free of corrosion.
7. 7

   Install new battery
   Place the new battery in the battery tray, ensuring it is seated properly and oriented correctly with positive terminal toward the front of the vehicle. The battery should sit flat and stable in the tray.
8. 8

   Install battery hold-down clamp
   Position the hold-down bracket over the battery base and install the hold-down bolt. Tighten to specified torque. The battery should be secure with no movement.

9. 9

   Connect positive battery terminal
   Place the positive (red) cable terminal onto the positive battery post. Ensure the terminal is fully seated on the post. Tighten the terminal bolt to specified torque using a torque wrench. Do not overtighten as this can damage the battery post.
   ⚠Do not overtighten terminal bolts beyond specification as this can crack battery posts
   Torque spec

   Battery Terminal Bolts6 Nm (4 lb-ft)
10. 10

    Connect negative battery terminal
    Place the negative (black) cable terminal onto the negative battery post. Ensure the terminal is fully seated on the post. Tighten the terminal bolt to specified torque using a torque wrench.

11. 11

    Apply terminal protection
    If desired, apply battery terminal protector spray or dielectric grease to both terminals to help prevent corrosion. Wipe away any excess.

Reassembly

1. Ensure all terminal connections are tight and secure
2. Verify battery hold-down clamp is properly torqued and battery does not move
3. Close hood and verify proper latching

Verification

• Turn ignition to ON position and verify dashboard lights illuminate normally
• Start engine and verify it cranks and starts properly
• Check that all electrical accessories function correctly (lights, radio, power windows)
• Reset clock and radio presets as needed
• Perform power window auto-up/down relearn if necessary: fully lower window, then raise and hold up button for 2 seconds after fully closed
• Monitor for proper charging system operation (battery warning light should turn off after starting)
