Sorry if this is Electrical Engineering pre-school. I'm a software guy that hasn't taken a class involving voltages for 10+ years.
I'm working on an Arduino project that will have to be fairly mobile. I'm using a Nema-17 stepper motor that is rated at 12v 1.2a (link to specs). I'm looking for a suitable battery to power my motor for around an hour. I found a 12v 2000mAh battery (link to battery). This (according to my knowledge) means this battery should be able to power my 1.2a motor for around 1.6 hours.
My question is; will my motor only draw what it needs(assuming I don't short it) or will the battery pump too much power and fry my motor? Any help Would be great!

As the battery is the right voltage for the motor, the motor should not draw more than its rated current, unless mechanically overloaded.
