## Does Running the Engine Charge a Car Battery?
##
While driving, the alternator is responsible for charging the car battery. The alternator is driven by the engine’s crankshaft and converts mechanical energy into electrical energy. This electrical energy is then used to power the car’s electrical systems and to charge the battery.
##
If the engine is not running, the alternator cannot generate electricity and the battery will not be charged. However, if the engine is running and the alternator is not working properly, the battery will not be charged and the car will eventually run out of power.
##
There are a few things that can prevent the alternator from charging the battery, including:
* A loose or broken serpentine belt
* A faulty alternator
* A blown fuse or a tripped circuit breaker
* A bad battery connection
* A problem with the wiring harness
##
If you suspect that your alternator is not working properly, you can have it tested by a qualified mechanic. If the alternator is found to be faulty, it will need to be replaced.

Here are some tips to help keep your car battery charged:
* Avoid leaving your car parked for long periods of time. If you must leave your car parked for an extended period of time, disconnect the battery negative terminal.
* Make sure that the serpentine belt is tight and in good condition.
* Have your alternator tested regularly, especially if you are experiencing any electrical problems.
* Keep the battery terminals clean and free of corrosion.
* If you have a battery charger, you can use it to charge the battery if it becomes discharged.

By following these tips, you can help keep your car battery charged and avoid being stranded with a dead battery.
