Step 2: Connect the Cables

Connect the red (positive) cable to the positive terminal of the dead battery and the other end to the positive terminal of the good battery.

Step 3: Start the Working Car

Start the engine of the car with the good battery. This will begin to charge the dead battery.

Once the dead battery is charged, disconnect the cables in the reverse order that they were connected. Start with the black (negative) cable and then the red (positive) cable.

Step 6: Check the Dead Battery Again

Check the dead battery again to make sure it’s fully charged. If it’s not, you may need to repeat the process several times until it’s fully charged.
