Uhhhh, NO! What school did you go to?
The current depends on the VOLTAGE, especially in the DC world.
A car battery, with the exception of a fault like putting an
accidental short on it across the drill wires somehow, would
99.999% sure work fine both with and without the engine running.
A 1 ton 12V battery would work, too.
You'd want to be certain there could be no way to put a short
across the car battery, but that's easy to do.

Please quit guessing and rationalizing; it doesn't become you.
