Where is the positive and negative battery terminal located on the Mercedes-Benz E200?

The Mercedes-Benz E-Class has two batteries. The small battery is located behind the headlight switch, requiring the removal of the left dashboard panel for visibility. The main battery is situated at the rear right of the engine compartment. The battery maintenance methods for the Mercedes-Benz E-Class are as follows: Mercedes-Benz E-Class Battery Maintenance Methods: Avoid Long-Term Parking: Avoid leaving the car parked in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage. Avoid Repeated Starting: Car engines are harder to start in winter. Each start attempt should not exceed 5 seconds, with a minimum interval of 15 seconds between attempts. If the engine fails to start after multiple attempts, check other aspects such as the electrical circuit, ignition coil, or fuel system. Avoid continuous starting attempts, as this can lead to battery damage due to excessive discharge.

Don't randomly guess the battery location of the Mercedes-Benz E200. I learned a trick at the repair shop last time. The main starting battery is hidden at the rear right of the engine compartment - the red cover marks the positive terminal post, while the uncovered black one is negative, partially obscured by the air filter housing. There's also an auxiliary battery tucked in the trunk, accessible only by lifting the right-side storage compartment cover. Always wear insulated gloves during removal/installation, and remember: negative cable comes off last and goes on first. Heads-up - this car's electrical system is delicate; jump-starting must follow the manual's procedure to avoid frying the ECU and costly dealership repairs. Keep the trunk dry too, as blocked battery box drain holes can corrode the terminals.

My Mercedes-Benz E200 just had its battery replaced, and the location was quite tricky to find. The main battery is under the hood on the front right side, with the red-labeled positive terminal exposed next to the air filter box, and the negative terminal directly grounded to the chassis. The key point is there's also a backup battery in the trunk, which can only be seen by removing the felt cover of the right-side storage compartment. Together, these two batteries ensure the vehicle's power supply. When replacing the battery yourself, you need a T30 Torx screwdriver, and remember to disconnect the negative terminal first, then the positive to avoid short circuits. In winter, don’t let the battery voltage stay below 12V for too long—the electrical system in a Mercedes is highly sophisticated, and frequent discharges can lead to early retirement. If jump-starting, never connect the cables to the wrong terminals; a mistake here could cost you as much as a new battery in repairs.

A friend asked where the battery is in the Mercedes-Benz E200, and I just took a photo to show him. The main battery is crouched on the right side of the engine bay, with a red plastic cap covering the positive terminal. More interestingly, there's a second battery hidden on the right side of the trunk—just lift the black felt cover to reveal it, which mainly powers the infotainment system. If you're doing the removal or installation yourself, remember to wrap the wrench with insulating tape; metal tools touching the metal car body can really spark. For daily maintenance, just apply some grease to the terminals to prevent oxidation, and use a tester with start-stop detection function to check the voltage. If replacing the battery, it's recommended to choose an AGM model, as regular batteries can't handle the frequent discharges from the auto start-stop system.
