[DelWalter]

The battery of the Mercedes-Benz R300 is located under the hood, in the upper left corner of the engine compartment, near the front bumper. Definition of the battery: The vehicle's battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. Functions of the battery: During engine startup, it supplies power to the starting system, ignition system, electronic fuel injection system, and other electrical equipment in the car. When the engine is off or idling at low speed, it powers the vehicle's electrical devices. When the power demand exceeds the generator's supply capacity, the battery also participates in power supply. The battery acts as a voltage stabilizer for the entire vehicle's electrical system, mitigating impact voltage in the electrical system and protecting the car's electronic equipment. When the generator is operating normally, the battery stores excess electrical energy generated by the generator.
