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.

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.
