When your car is running the alternator is charging the battery and keeping the electrical system running. The battery provides power to start the engine and run the accessories when the engine is off. If the battery is weak or dead the car won’t start.
If you let your car idle for too long it will run the battery down and you may end up stranded. An idling car uses about a half-gallon of gas per hour so it’s not very fuel-efficient. It’s also not good for your car’s battery or engine to be running for long periods of time without moving.
If you’re going to be sitting in your car for more than 30 minutes it’s a good idea to turn off the engine and restart it when you’re ready to go. This will help preserve your battery charge and save fuel.
