The Mercedes-Benz Positive Battery Terminal / Junction Box Cover (OEM 1665450403) is a used genuine part, ready for installation. This cover shields the battery's high-current terminal and junction box from accidental contact, debris, and corrosion, which can cause electrical faults, no-start conditions, or blown fuses if left exposed. Also called the battery terminal cover or junction box lid, it’s a simple but critical piece of engine-bay trim.
