European and import platforms frequently use the Group 49 (also known as H8) footprint — and for those vehicles, the XS Power D4900 Group 49 12V AGM battery is the definitive upgrade. Dropping into the factory tray while delivering performance that stock AGM batteries cannot approach, it is the straightforward answer for enthusiasts who want a dramatic electrical upgrade without custom fabrication.
OEM Fitment, Competition-Grade Performance
With strong peak amperage, a high CCA rating, and substantial reserve capacity, the D4900 gives BMW, Audi, Mercedes, and other Group 49 platform owners the same caliber of sealed AGM power that dedicated car-audio builders rely on for SPL competition and high-output daily-driver systems. The extended warranty and XS Power's proven track record in the high output battery market make this a confident choice for anyone serious about the electrical performance of their vehicle.
