The speed of 12 volts isn't a measure of speed but rather voltage, which is the electrical potential difference. Voltage itself doesn't have a speed; instead, it represents the energy per unit charge. In an electrical circuit, the speed at which electrical signals travel is determined by the medium through which they move, typically at a fraction of the speed of light. Thus, 12 volts simply indicates the potential energy available for electrical work, not a speed.
A twelve volt charger will charge twelve volt batteries only unless it has a feature that allows you to change the chargers voltage. But on fast or slow charge 12 volts is 12 volts so most 12 volt chargers are only good for 12 volt batteries.

No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.

Definately 12 volt.
1971s had 12-volt systems.
use two 12 volt batteries in series.
It is 12 volts.

Positive 12 volt
If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
