No it can't.

Why not?

6v gets you max power delivered from the battery...

I've got an accurate voltmeter sitting across my car battery at all times
the ignition is on, and I can assure you it never drops under nine point
something volts even on the coldest day when starting. Usually the high
10s. If you think about it, old cold start ignition systems are designed
for 9 volts minimum.
