Newton is correct.
Both AndrewJ and I have at various times been driving around with 130+ lbs of extra batteries in our vehicles when running with the alternator disconnected. Both of us saw significant efficiency gains in all types of driving.
EPA estimates 100 lbs equates to a 2% decrease in fuel economy. (They don't
state under what conditions.) The alternator delete is worth 6 to 10% better fuel economy from my and Andrew's experience. Simple math.
