Solution

1. Preparation

Gather tools and safety equipment.
Tools Required: Multimeter, jumper cables, socket set, wire brush, safety gloves, and safety glasses.
Ensure the vehicle is parked in a safe location and the ignition is off.

2. Clean Battery Terminals

Disconnect the negative (-) terminal first, followed by the positive (+) terminal.
Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Ensure a tight connection when reattaching terminals (positive first, then negative).

3. Test the Battery

Reconnect the battery terminals securely.
Use a multimeter to check the battery voltage. If it's below 12.4 volts, proceed with charging the battery.
Tools Required: Multimeter.
If the voltage is above 12.6 volts, the battery may be fine, indicating another issue.

4. Jump-Start the Vehicle

Connect jumper cables to the dead battery (positive to positive, negative to metal ground).
Start the working vehicle and let it charge the dead battery for a few minutes, then attempt to start the Honda Civic.
If successful, allow the vehicle to run for at least 20 minutes to recharge the battery.

5. Replace the Battery (if necessary)

If the battery fails to hold a charge, it may need replacement.
Remove the old battery by unbolting the battery hold-down bracket and disconnecting the terminals (negative first).
Install the new battery, ensuring proper orientation and secure connections.
