Step 3: With both cars off and in “park,” connect the jumper cables in the following order:
- Connect one red clamp to the positive (+) battery post of the “dead” battery.
- Connect the other red clamp to the positive (+) post of the good battery.
- Connect one black-end clamp to the negative (-) post of the good battery.

How do you jump start a dead battery?
Steps to Jump-Start a Car

How do you know if jumper cables are working?
Jumper Cable Output Test –
Can a battery be too dead to jump?
YES, a car battery can get so dead it will not receive a jump start anymore. To cut to the chase, and just before we get to the meaty stuff, a “dead” car battery is an indicator of different factors—and almost always, these occur all at the same time.
Why don’t you connect the negative when jumping a car?
Caution: Don’t attach the negative cable to the negative terminal of the weak battery when jumping a car battery! This common mistake could ignite hydrogen gas directly over the battery. Battery explosions can cause serious injury. Finally, remove the positive cable from the car with the weak battery.
How long should you leave jumper cables on?
Turn on the engine in the good car and wait two minutes. Then turn on the bad/dead one and wait an additional two minutes. From there you’ll remove the cable in the reverse order at which you put them on, and you’ll let the car run for two more minutes before you get back on the road.
How long does it take to charge a car battery with jumper cables?
What gauge jumper cables do I need?
A standard set of jumper cables has a gauge rating of six. The smaller the gauge rating, the thicker the cables are. The thicker the cables are, the more effective they’ll be. Nevertheless, a set of jumper cables with a gauge rating of eight should provide enough power to jump start most vehicles.
