No: an EFB cannot handle the charging profile and cycling of a system designed for AGM, and it will fail early. ### Do I need to register the new AGM battery? On most cars with battery management, yes, using a diagnostic tool. ## Choose by brand The same aGM Start-Stop batteries, filtered by manufacturer.
