Where is the battery located in the Mercedes-Benz GLE400 4MATIC?
3 Answers
The battery of the Mercedes-Benz GLE400 4MATIC is located under the front passenger seat. Functions of the battery: Supplies power to electrical equipment, absorbs voltage spikes in the electrical system. When starting the engine, the battery provides power to the starting system, ignition system, and electronic fuel injection system. When the engine is off or idling at low speed, it supplies power to the vehicle's electrical equipment, absorbs voltage spikes in the electrical system to protect electronic devices, and stores excess electricity generated by the alternator. Battery maintenance methods: Avoid parking the car outdoors for extended periods. In winter, avoid multiple uninterrupted attempts to start the car. Keep the car battery regularly charged. Clean the battery terminals periodically and apply grease to protect the wiring harness.
I've driven the Mercedes-Benz GLE400 4MATIC for several years, and the battery is usually located beneath the floor panel in the trunk. Lift the trunk carpet or mat, and you'll see a plastic cover. Unscrew it to access the battery. This design ensures better weight distribution, reducing front-end load and improving driving stability. Once, while checking it myself, I forgot to disconnect the negative terminal first and touched the positive one—a spark flashed, which was quite frightening. Since then, I always remember to use a wrench to remove the negative terminal first before touching anything else. Additionally, Mercedes often places the battery here because the engine bay is compact, accommodating more electronic components. It's advisable to regularly check the terminals for oxidation or green corrosion—cleaning them can extend the battery's lifespan. If the battery struggles in cold weather, jump-starting from this location is also convenient.
I'm familiar with the layout of Mercedes-Benz vehicles. The battery of the GLE400 is mostly located under the floor of the trunk, requiring the removal of a cover to access it. Placing it here helps optimize the front-to-rear axle weight ratio, enhancing handling responsiveness and reducing body roll during turns. Simply lift the trunk carpet or mat to find a small cover panel, then remove a few screws. Always disconnect the negative terminal first during operation to avoid short circuits that could damage electronic modules. Mercedes-Benz designed it this way for efficient space utilization, as the engine bay is crowded with high-voltage components. If the battery is dead, jump-starting from here is quicker. For routine maintenance, keep the electrode contact points clean to prevent dirt buildup from affecting current flow. Regularly check the battery voltage with a voltmeter to ensure it stays above 12V, ensuring reliability in critical moments.
