In case people can't understand batteries.... here's how to think of it....
If I get those tiny watch batteries, they're 1.5v... if I put 8 in a line, i get 12 volts.
This CANNOT start a car.... it's no the voltage
The MATHS formula is
watt=amp X volt
Watts = Power... higher watt light bulb, brighter light.
But to get that power, you need a certain current x volts. If the voltage is low, you would need MORE current to create enough WATTS, and it cannot draw more, so it won't start.
Similar, if you have lots of Volts, but current draw is low (like little button batteries) you cannot get enough WATTS, and cannot start that car....
