Learn moreDo Mercedes batteries need coding?
Yes. Every AGM/EFB battery installed in a Mercedes must be registered with the Battery Management System, otherwise charging is incorrect. We include coding in our service.
Do you replace Mercedes voltage converter or auxiliary modules?
No. We replace and code the main starter battery. Voltage converter modules and auxiliary electronics parts are not stocked here and need a Mercedes workshop.
