Jump starting a car takes only 10 minutes with the preparation if you have the necessary tools available and you know all the safety rules. For example, beefore you get started, make sure that your jumper cables are in good condition and of course they should be long enough to easily reach between the car with the good battery and the car that needs juice. There should be no exposed wire and the rubber coating should be free of cracks or damage. [1]https://www.lifehacker.com.au/2020/02/how-do-i-jump-start-a-car-2/
According to Car & Driver [2]https://www.caranddriver.com/features/a15145141/drivers-education-the-6-things-every-driver-should-know-how-to-do/, With both cars off, attach one of the red clamps to the positive (+) terminal on the battery that’s presumed bad. Be careful of the other red clamp—it’s now live. Then connect that other red clamp to the positive terminal on the jump car’s battery. After that, one black clamp goes to the negative (-) terminal on the good battery while the other black clamp should go to an unpainted steel surface on the stalled car, to be grounded. Start the car with the good battery. Routing the cables this way uses the battery on the live car to start the disabled car, so there is no need to wait for the dead battery to charge. Start the dead car. Remove the cables in reverse order, close the respective hoods, and operate the two cars as usual. If the electrical system in the car with the drained battery is otherwise okay, the battery should be recharged after about 15 minutes of driving and the whole thing should be okey-dokey.
According to GEICO [3]https://www.geico.com/living/driving/auto/auto-care/how-to-jump-start-your-car/, 30 min or even 20 min of driving might give your battery enough power to start your car next time, but a longer time is better. But each emptying of a battery from power, which required the jumpstart, makes the battery worse and shortens the time until the battery needs to be replaced.
