I hope you guys are leasing, because the resale will drop like a rock. Good luck.
...And it does not beat the hell out of the battery because heavy instantaneous loads for short periods don't take much total energy. If it did, then the start/stop idea would be self defeating since the starting energy has to be put back in when the engine is running. As it stands, the amount that the starter takes is equal to about 3 - 4 seconds of power used at idle. Not to mention that the battery is expressly designed to provide power to impulse loads and does this better than most other things it is called upon to do in a car.
