- Focus on the critical milestones: Position the cars correctly and Start the dead car and disconnect in reverse.
- Read the fact-checked tips and warnings to avoid common pitfalls during execution.
Step-by-Step Instructions
Position the cars correctly
First, you need a 'donor' car with a working battery. Park the working car facing the dead car, or park them side-by-side, so their engines are as close as possible. Make absolutely sure the two vehicles are not physically touching each other. Put both cars in Park (or Neutral if it's a manual), engage the parking brakes, and turn the engines completely OFF. Take the keys out of the ignitions to be absolutely safe.
Connect the cables in the exact right order
This is the most critical step. Memorize this sequence. First, clamp a RED cable to the positive (+) terminal of the DEAD battery. Second, clamp the other end of the RED cable to the positive (+) terminal of the GOOD battery. Third, clamp a BLACK cable to the negative (-) terminal of the GOOD battery. Finally, clamp the other end of the BLACK cable to a piece of unpainted metal inside the engine bay of the DEAD car (like a shiny bolt on the engine block itself). Do NOT clamp this last black cable to the dead battery's negative terminal; doing so can create a spark directly over the battery, which is dangerous.
Start the donor car and wait
Start the engine of the working car. Let it run for about three to five minutes. This allows the alternator in the good car to actively push a charge into the dead battery. You can even rev the engine of the good car slightly (pressing the gas pedal a tiny bit) to speed up the charging process. Do not try to start the dead car immediately; it needs a minute to soak up some juice.
Start the dead car and disconnect in reverse
Now, try to start the dead car. If it starts, wonderful! Leave it running. If it just clicks, wait five more minutes and try again. Once the dead car is running smoothly, you must disconnect the cables in the exact REVERSE order of how you put them on. Remove the black cable from the metal ground, then the black cable from the good car, then the red cable from the good car, and finally the red cable from the previously dead car. Keep the newly revived car running for at least twenty minutes so its own alternator can fully recharge the battery.
