Battery Replacement on Mercedes A-Class and B-Class

Model: Mercedes Classe B W245, MK 1 - Years 2005-2011
Part: Battery

On Mercedes A-Class and B-Class models produced until 2012, the battery is located under the driver's footwell. Accessing it is extremely simple: first, remove the mat, then unscrew the retaining clip of the footwell with any flat tool, such as a flathead screwdriver. Once the footwell is removed, there you have it! The battery is in an unusual location, which is why many people struggle to locate it. When replacing the old battery, always disconnect the negative terminal first, followed by the positive. Remove the old battery, insert the new one, and proceed in reverse for reassembly.
