These methods may help you get your car moving again, and might save you the hassle of having to call for a tow or a jump start.

1. Jump-start your car

If your car battery is too weak to start the engine, you may need to jump-start your car. You will need jumper cables and another vehicle with a good battery. Connect the red cable to the positive terminal of the good battery and the other end to the positive terminal of the dead battery. Then connect the black cable to the negative terminal of the good battery, and the other end to an unpainted metal surface of the dead car’s engine. Start the vehicle with the good battery and let it run for a few minutes, then try to start your car.

Be careful not to damage the transmission.

Checking the Battery Connections

Checking the Battery Connections

Step 1: Inspect the Battery Terminals

The first step in checking your battery connections is to inspect the battery terminals. Look for any signs of corrosion or damage. If the terminals are corroded or covered in a white or greenish substance, this could be a sign of battery acid leakage.

Step 2: Tighten Loose Connections

If the battery terminals are loose or not making a tight connection, the battery may not be able to hold a charge, or it may not be able to transfer the charge to the starter. Use a wrench or pliers to tighten any loose connections.

Step 3: Clean the Battery Terminals

Step 3: Clean the Battery Terminals

If the battery terminals are corroded, you may need to clean them. You can use a wire brush or a special battery terminal cleaner to remove the corrosion. Be sure to wear gloves and eye protection when handling battery acid. After cleaning, coat the battery terminals with petroleum jelly to help prevent further corrosion.

Step 4: Check the Battery Cables

Step 4: Check the Battery Cables

If the battery terminals and connections are in good condition, the problem may be with the battery cables. Use a voltmeter to check the voltage drop across the cables. If the voltage drop is too high, the cables may be corroded or damaged and need to be replaced.

Step 5: Consider a Battery Replacement

If the battery connections are in good condition and the cables are not the problem, it may be time to consider replacing the battery. A battery that is low on charge or is too old may not be able to hold a charge, which can make it difficult to start the engine.
