  • Although both AGM and EFB technologies are used for Start-Stop applications, there are some differences in the technologies' performance. While EFB is an improved flooded battery, AGM is a battery specifically designed for demanding applications and able to support any types of Start-Stop systems and even xEV.

    Downgrading from an AGM to an EFB is not recommended since the vehicle's Energy Management System is designed for a certain battery performance. Upgrading from EFB to AGM on the other hand, is always possible and advised when your customer faces recurring battery issues.
