No, batteries provide the necessary power to turn over the engine when starting and back up power to power alarms, clocks, internal computers and accessories when sitting with the engine off and the key in accessory mode.

Absolutely not. The only possible way it would affect it is if you used several heavy equipment batteries and affected the weight of the car terribly. In fact, a larger battery would probably recharge faster than a smaller one and since the battery acts as the buffer of sorts in your electrical system, it would prevent the alternator from needing to be powered up so often. If you want to see what an alternator robs from your engine just remove the belt, power the rotor and try to turn it by hand. Good luck.

The weight of the battery is the only factor for gas mileage. For a car with one battery (not a hybrid) the differential would be very small.

If the battery is 'dead' and won't hold a charge, then it would require constant /continuous recharging and that would make your alternator work harder. But generally , no, the battery will affect the starting of the car, but not the gas millage once it's started.

No. The battery is there to start your car and to make sure there is enough electricity available for when the alternator is running so slow that it could not keep the engine in electricity.
Neither of those affects your gas mileage.

I agree with 'Jimando' that the battery type should not affect your gas mileage unless you have a bad or weak battery that has the alternator working constantly to keep it recharged.

no it doesn't. The only time gas is ever connected to the battery is during the ignition procedure which is basically nothing.

no, it has nothing to do with your gas milage.
