Question about Varta A7 Dynamic (E39) AGM xEV 570 901 076 Car battery 70Ah (Silver Dynamic)

Although the Varta Silver Dynamic AGM A7 could fit in principle, with a capacity of 70 Ah and a length of 278 mm it is designed more for smaller vehicles. For the Mercedes CLK Cabrio W209, a larger battery with approx. 90 Ah and 315 mm in length is generally recommended to ensure the performance and range of the power supply specified by the manufacturer.
