Will a car start with 9 volts?
if you actually had a 9 volt battery that could put out about 100-200 amps for 10-20 seconds, that probably would start the car. a real car battery drops way below 12v while it is starting. if your 9 volt was so strong that it would not drop below 9V, then it would probably work.
How many volts do you need to start a car?
