It really depends on what the motor is driving. The only way you will get reliable data is to take current measurements in use and calculate from that, or actually do a timed test.

P=VI

I=.3/6=50ma,

working hours will be t=500maH/50ma=10H

but if you use 5 volts then it will be t=500/60=8.33H(you have to use 5V ,other wise your equipment life time will reduce)

By the way "4.5-5volts (vmax)" is nonsense for a DC motor.
I'll bet a tin of my finest tuna it will be fine at 6v, it will of course draw a little more current.
Most DC motors will run fine on a large voltage range.

GA for the sound words of wisdom, Del.

As well, I offer premature congratulations for GA #300. Well done. Help yourself to a tin of the finest tuna available, LynDoor™ Industries "Chicken of the Ocean"!
