If your car battery clicks but won’t start, it’s likely due to insufficient charge. In this case, you should let your car battery charge for at least 30 minutes to an hour using jumper cables or a battery charger. This time frame allows the battery to gain enough power to start the engine.

Why Does My Car Battery Click but Won’t Start?

When you hear a clicking sound while trying to start your car, it usually indicates that the battery is too weak to turn the engine over. This can be caused by:

• Low Battery Charge: The battery may have lost charge due to leaving lights on or not driving the car for an extended period.
• Corroded Battery Terminals: Corrosion can impede the flow of electricity.
• Faulty Alternator: The alternator may not be charging the battery properly.
• Old Battery: Batteries typically last 3-5 years; an old battery may not hold a charge well.

How to Charge Your Car Battery Safely

Using Jumper Cables

1. Park the Vehicles: Position a working car close enough to your car for the cables to reach.
2. Turn Off Engines: Ensure both cars are off before connecting cables.
3. Connect Jumper Cables:
   • Red clamp to the positive terminal of the dead battery.
   • Red clamp to the positive terminal of the good battery.
   • Black clamp to the negative terminal of the good battery.
   • Black clamp to an unpainted metal surface on your car (not the battery).
4. Start the Working Car: Let it run for a few minutes.
5. Attempt to Start Your Car: Try starting your car. If it starts, let it run to charge further.

Using a Battery Charger

1. Connect the Charger: Attach the charger clamps to the battery terminals (red to positive, black to negative).
2. Set the Charger: Choose the correct voltage and amperage setting.
3. Turn On the Charger: Allow the battery to charge for 30 minutes to an hour.
4. Check the Charge: Attempt to start the car; if it starts, let it idle to continue charging.

How Long Should I Charge My Car Battery?

The charging time depends on the method and the battery’s condition:

• Jumper Cables: 30 minutes to an hour should be sufficient to start the car.
• Battery Charger: Depending on the charger’s output, it may take 1-4 hours to fully charge a depleted battery.

Tips for Maintaining Your Car Battery

• Drive Regularly: Short trips may not fully charge the battery; longer drives help maintain charge.
• Clean Terminals: Regularly check and clean battery terminals to prevent corrosion.
• Check Battery Health: Test your battery’s health every few months, especially before winter.
• Turn Off Electronics: Ensure lights and accessories are off when the car is not running.
