A fully charged battery will read 12.6 volts. The engine needs somewhere between 20,000 and 50,000 volts or maybe higher to fire the spark plugs. The ignition system is divided into two sections, the primary circuit and the secondary circuit. The low voltage primary circuit operates at alternator voltage (13.5 to 15.5 volts engine running) and is responsible for generating the signal to fire the spark plug at the exact right time and sending that signal to the ignition coil. The ignition coil is the component that converts the 12 volt signal into the high 20,000+ volt charge. Once the voltage is stepped up, it goes to the secondary circuit which then directs the charge to the correct spark plug at the right time.

A plug doesn't have any volts in it until you plug it into a wall outlet. A typical electrical wall outlet in a typical house in the US delivers electricity at @ 110 volts. Different countries in Europe use electricity that's around 200 volts; twice as many.
