No. The mah rating does have to do with the life-span of the battery when the current draw is less than the mah rating by a fair stretch. In your case, 600mah is simply way too small. With a 3000+ mah battery, you could talk about how many rounds/charge, but first you need to be able to run the motor from any piston position. This will include during near-maximum spring compression.
The battery voltage will indicate to you how fast your motor will turn and how quickly the magnetic field in the motor windings builds up, but it has nothing at all to do with the magnetic strength of your motor field (ie. the abitlity of the motor to overcome the inertia of the connected load). Current is what you want. If you have to sacrifice one for the other, give up voltage to get more current. Your gun would run rather well on a 7.2v 4000 mah battery, but 12v 600 mah gives you the problem you're currently having.
Sometimes battery fit is an issue as most AEGs offer limited space for batteries. If you have trouble with this, give up #'s of cells (10 for 12v) and go with a lower voltage and bigger mah (6 cells for 7.2v).
