We install OEM or OEM-equivalent AGM or specified battery types that meet Mercedes‑Benz electrical requirements. This ensures the alternator’s charging strategy, battery management algorithms, and ancillary systems function as designed. Beyond proper selection, our technicians perform post-installation tests and register the battery in the vehicle’s control modules when necessary, guaranteeing reliable operation and protecting your investment.
