Remy 20405 | Alternator

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.

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.

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