Can jumper cables damage your car?
A damaged battery has the potential to start a fire when placing the jumper cables on. Car batteries contain sulfuric acid that can become vapors, leaking out of vents. These vapors can be highly flammable. Jumper cables are known to cause sparks and can ignite these vapors, causing fires or even possibly an explosion.
How long does it take to jump a car?

Does it matter what jumper cables you use?

How long should I leave my car on after jumping it?
When jumping a car, you should leave your car running for at least 30 minutes after a jumpstart. For more reliable results, drive it around instead of letting it idle. This should fully charge the battery so it won’t die on you again.
Can you mess up your battery by jumping another car?
Jump starting a car very basically places the “donor” car’s battery in parallel to the “dead” car’s battery (and alternator current), so the deceased car can start off of the donor car’s battery instead of its own.
Does revving the engine charge the battery?
The battery will charge faster if you rev the engine faster. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.
