Do cars use more fuel when running with headlights switched on?

[paddiez]

Yes.

no! the headllights have nothing to do with fuel, they use battery power.

[ChuckFickens]

yes they do, but it's a minimal amount more

(x_x_x_1, and what charges the battery on a car)

[x_x_x_1]

the battery charges when the car is start and is running, thats why batteries tend to die when a car hasnt been started for a long perid. the alternator charges the battery.
