How long to jump a car

If the battery is dead, you'll need to jump-start the car with another vehicle. to do this, connect one end of a cable to each car's positive terminal and the other end of the cable to your engine block. it's important that you use an insulated type of jumper cables or else any sparks may ignite gas fumes around your engine compartment. most cables are also coated in rubber; make sure not to touch them once they're connected as it'll make it too difficult for electricity to flow through them, risking an explosion if anything hazardous is nearby like fuel or oil.
when the second vehicle's headlights go off (indicating that there is no more power), turn off both engines before detaching either end

how long should it take to jump a car?

it should take around five to ten minutes for someone with experience to jump a car, but it may take longer or shorter than that depending on the condition of the battery.

a typical car battery starts at 12 volts and has enough stored charge to crank up an engine twice before needing a recharge. the tricky part about jump-starting your vehicle is connecting the two batteries safely so there's no risk of sparking.
it's important not to let any metal surfaces touch other metal surfaces during this process because sparks could set you or your vehicle on fire if both posts are connected simultaneously, instead disconnect one end first then connect them together in sets. connect negative first then positive which will produce sparks upon contact, after the completion wait 20 seconds before

how long does it take to jump a completely dead battery?

grab a battery pack with jumper cables, or call for roadside assistance. cars that are completely dead will not start on their own without stimulation from outside sources. the biggest problem is the loss of electricity to the starter's electric solenoid so it cannot move its plunger to turn over the engine. this can be solved by connecting an external power source to these 3 terminals on any 12 volt automotive battery – clamping shorts across two posts at one time for just a few seconds is usually more than enough charge, but you should wait 10 minutes between connections because it drains some energy from your device too. usually one connection lasts sufficiently long enough to allow ignition if cranking the engine first fails first…or if you have already had time

how long do you leave jumper cables on a car?

generally 10 minutes.

this is an objectively wrong answer to an objective question! allow me to explain why i wrote it…

ideally you should wait until your dead car makes a whole bunch of noise signaling that it is about to start up again, but this wastes time and gas driving back and forth – plus who has 10 minutes to spare? wait for 5-10 seconds after the battery starts feeling like its charging (you may hear rapid clicks) before removing cables. and remember that ratchet clamps are always better than no clamps at all.

can you jump a completely dead battery?

no, you can't.

in order to jump a vehicle with a dead battery, another running car is needed which can be wired up to the battery system of the broken down car and create a pulse of energy which will be enough for engine cranking. the noise created from this usually scares away any creatures in the area who have hearing better than humans. erratic pulses from electric current or an electrical disturbance may also cause disruptions in delicate electronics which could result in further damage that may cost more money to repair. in other words, it's probably not worth breaking your arm trying to fix it out there when help is just an hour away at home! don't try it alone!!
