Visually Inspecting the Battery: Look for signs of corrosion or damage on the battery terminals and cables.

Load Testing: Use a multimeter to check the voltage of the battery. A healthy battery should have a voltage of around 12.6 volts.

What To Do If Your Car Battery Dies

When your car battery dies, jump starting the car can help you get back on the road quickly. To do this, you’ll need a set of jumper cables and another vehicle with a working battery. Connect the positive cable to the positive terminal on your battery and the other end to the positive terminal on the assisting vehicle. Then, connect the negative cable to the negative terminal on the assisting vehicle and attach the other end to an unpainted metal surface on your car.

If jump starting the car doesn’t work or if your battery keeps dying, it may be time to replace the battery. Look for signs like slow engine cranking, dim headlights, or a battery that is more than three years old. Make sure to purchase a battery that matches the specifications of your car and follow the instructions to safely replace it.

If you are unsure about jump starting or replacing the battery, it’s best to call for professional help. An automotive professional can assess the situation, determine the cause of the battery problem, and provide the necessary repairs or replacements. Avoid attempting complex repairs on your own if you are not confident in your abilities.
