same here, i dont turn on air con in the morning and night, driving without air con saves more fuel than the i-stop
i guess i-stop have to work together with i-eloop to get the best fuel savings, iinm, in US they tested i-eloop save 1mpg for every tank
but from the fuel savings vs battery replacement cost, it is not worth it at the moment, not until the start-stop battery drop to the same price as current maintenance-free battery

May I know what type of battery Mazda 3 is using? Q-85? If it is the same as Mazda 2, I managed to find a company which sell Q-85 battery at half the price quoted by SC. Need to check whether it is maintenance free or not. My SC tells me stock battery is under the 3 years / 100,000km warranty and can change only once throughout. Anyone can reconfirm this statement?

*Edit: I am sorry everyone, someone enlightened me, Q-85 is supposed to be battery designed for idle-stop or start stop vehicles, not your normal UHPB 95D23L. Most probably, it is Enhanced Flooded Battery (EFB) design. A common way to identify it is it will indicate it is intended for idle-stop or start stop vehicles.
