The volts on cordless drills are based on the battery power. The volt rating reflects the battery that is in the drill.
You can't, you need to get a replacement battery for the drill.
Unfortunately, no. You'll need a 12v battery for the drill or a 14 v drill for the battery.
You must drill on.
it controls the speed. when the diode is busted it gains into fullspeed
That will vary from manufacturer to manufacturer and sometimes from one tool to another that a manufacturer makes.
Yes, of course they make a battery. 1 or 2 come with the drill
