Solution

1. Preparation

Gather tools and parts required:
- Tools: Jumper cables, multimeter, socket set, battery terminal cleaner or brush, gloves, safety glasses.
- Parts: Replacement battery (if needed).
Ensure the vehicle is in park (automatic) or neutral (manual) and the engine is off.

2. Jump-Start the Battery (if applicable)

Connect the positive (red) jumper cable to the positive terminal of the dead battery.
Connect the other end of the positive cable to the positive terminal of the working battery.
Connect the negative (black) jumper cable to the negative terminal of the working battery.
Connect the other end of the negative cable to a metal ground on the dead vehicle (not the negative terminal).
Start the functioning vehicle and let it run for a few minutes, then attempt to start the Camry.

3. Remove and Replace the Battery (if necessary)

Disconnect the negative terminal first (black) from the dead battery, followed by the positive terminal (red).
Remove any battery hold-down brackets using a socket set.
Carefully lift the old battery out of the tray; ensure it is done safely as batteries can be heavy.
Clean the battery tray and terminals with a battery terminal cleaner or brush.
Place the new battery in the tray, ensuring correct polarity (positive to positive, negative to negative).
Reattach the hold-down brackets to secure the battery.
Connect the positive terminal first, followed by the negative terminal.

4. Verify Battery Functionality

Start the vehicle to ensure it runs smoothly.
Monitor the dashboard for any warning lights.
Check the battery voltage with a multimeter after starting the car to ensure the alternator is charging the battery correctly.
