Solution

1. Preparation

Gather tools: Multimeter, socket set, wrench set, jumper cables.
Ensure the vehicle is in a safe location and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Voltage
- Connect a multimeter to the battery terminals.
- If the voltage is below 12.4 volts, recharge the battery using a battery charger.
Clean and Tighten Terminals
- Inspect battery terminals for corrosion. If present, clean using a mixture of baking soda and water.
- Tighten the terminals securely.
Replace Battery (if necessary)
- If the battery fails to hold charge after recharging, remove it using a socket set.
- Replace with a new battery of the same size and specifications, ensuring proper polarity during installation.

3. Jump-Start Procedure

Connect Jumper Cables
- Connect the red (positive) jumper cable to the positive terminal of the dead battery and the other end to the positive terminal of the working battery.
- Connect the black (negative) jumper cable to the negative terminal of the working battery and the other end to a clean, unpainted metal surface on the dead vehicle.
Start the Working Vehicle
- Allow the working vehicle to run for a few minutes before attempting to start the Honda Accord.
Attempt to Start the Accord
- Turn the key in the ignition. If it starts, let it run for at least 15 minutes to recharge the battery.
