No, the alternator is not designed to drain the battery. Instead, it charges the battery while the engine is running. If your battery is being drained, it could be due to a variety of factors, and it's recommended to have your vehicle inspected by a mechanic.

The variable voltage alternator system is commonly controlled by the PCM in modern vehicles.

Alternators convert mechanical energy from the engine into electrical energy to power the vehicle's electrical system and charge the battery. They consist of a rotor, stator, and voltage regulator, which work together to produce electrical energy that is used to power the vehicle's electrical components and charge the battery.

To determine which alternator you need, consider your vehicle's make and model, engine size, and electrical system requirements.

Replacing your car's alternator yourself can be an option to save on repair costs. PartsHawk.com offers a variety of new and remanufactured alternators to fit your needs. However, keep in mind that DIY alternator repair is for those who are comfortable working on cars and have the necessary tools.
