Mercedes S550 Replacement Alternator Information
The alternator in your Mercedes S550 lets your engine charge the battery. Without it, you'd need a jump every time you started the car. Alternators are basically electric generators that translate rotational force to electric power. They're driven by the torque generated by the combustion engine, and as they turn, they create a current which is used to charge the battery up. This ensures that your battery lasts longer. Alternators like those found in Mercedes S550 vehicles require specific amounts of torque and rotational speed to turn their dense coil assemblies and generate the correct charging current as well as circuits that convert the AC they create to DC for charging . They also use a voltage regulator circuit that ensures their output is kept at stable levels. When the alternator in your Mercedes S550 dies, your battery will be unable to maintain any charge.
They are available for the following Mercedes S550 years: 2011, 2010, 2009, 2008, 2007, 11, 10, 09, 08, 07. This part is also sometimes called Mercedes S550 Car Alternators.
