GM3/GM9 strength at low voltage?

I need help from someone who owns a solarbotics geared motor type GM3 or GM9, or even better: both!

I wantot to know how strong they are when driven directly from a single AAA 1,5 Volt battery. If you hook it up to the battery and hold on to the axle/output shaft, will the motor be able to spin itself around? Would it be able to keep spinning if you taped the battery onto the motor body, or would the added weight of the battery be to much to keep whole contraption rotating around its own axle?
