Yes, a week continuous. If time permits, two weeks.
On "forklift" style DC motors, the brushes will last for many, many
years of operation. When run on ~12 volts at zero load for a week, you
just start to get an a hint of curvature in a square-faced brush. Best
to "pre-shape" the brushes with a curve that is close to the commutator
diameter or it will take a looong time to break in the brushes.

Is that a week continuous?
