Directly powered:
* Starter Motor: The most well-known function of the car battery. It provides the initial burst of power to crank the engine and get it running.
* Ignition System: The battery provides power to the ignition coil, spark plugs, and other components that create the spark needed to ignite the fuel-air mixture in the cylinders.
* Lights: Headlights, taillights, interior lights, and instrument panel lights all run on the battery's power.
* Radio and Entertainment Systems: The car radio, CD player, and any other entertainment systems are powered by the battery.
* Power Accessories: This includes items like power windows, power locks, power seats, and even the air conditioning system in some vehicles.
Indirectly powered:
* Charging System: The battery is also used to store power generated by the alternator, which then supplies power to the rest of the car's electrical system while the engine is running.
* Fuel System: The battery powers components in the fuel system, like the fuel pump, which is crucial for delivering fuel to the engine.
Important Note: While the battery is the primary source of power for all these components, the alternator takes over once the engine is running, continuously recharging the battery and providing power to the electrical system. This creates a closed loop, keeping the electrical system operational.
