Where is the battery located in a Mercedes-Benz car?
2 Answers
Mercedes-Benz battery is located in the upper right corner of the engine compartment. The functions of the battery are as follows: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or idling at low speed, it provides power to the car's electrical equipment; 3. When the generator's output is insufficient, it supplies power to the electrical equipment; 4. It mitigates voltage surges in the electrical system and protects the car's electronic devices; 5. It stores excess electricity generated by the alternator. The maintenance methods for car batteries are as follows: 1. Avoid parking the car in an open parking lot for long periods; 2. In winter, avoid multiple uninterrupted starts of the car; 3. The car battery should be charged frequently; 4. Regularly clean the battery terminals and apply grease to protect the wiring harness.
I found that the battery in Mercedes-Benz cars is usually located under the hood, in the front-left or right corner area, which is quite noticeable and easy to find. However, many newer SUV models like the GLK or GLC hide the battery under the trunk floor—lifting the floor panel reveals a dedicated box housing it. When I drove a Mercedes, I often checked there because incorrect battery placement can cause winter starting issues. I recommend cleaning the terminals every six months to prevent corrosion, extend lifespan, and ensure smooth ignition. This design change aims to free up engine bay space for other components, but remember, battery placement varies by model year—older C-Class models may still have it in the traditional spot, while newer hybrids might place it under the seats. Always consult the manual or a professional before handling to avoid mistakes.
