The Varta Silver Dynamic series stands out as one of the most powerful and reliable ranges of conventional lead-acid batteries on the market. Designed for vehicles requiring exceptional starting performance and high energy demands, Silver Dynamic batteries offer consistent power even in extreme conditions. They are ideal for cars equipped with multiple electronic devices but without start-stop systems. Known for their advanced calcium-silver technology, these batteries provide higher corrosion resistance, longer service life, and excellent cold cranking capabilities. This combination of durability and power makes them a preferred choice among drivers seeking top-level reliability and performance.
The Varta Silver Dynamic D39 battery is a strong representative of this premium line. With a capacity of 63 Ah and an impressive cold cranking amperage of 610 A, the D39 ensures a quick and reliable engine start even in cold weather. Built with a standard lead-acid structure, it is perfect for vehicles that need consistent energy but are not equipped with start-stop technology. Measuring 242 mm in length, 175 mm in width, and 190 mm in height, it matches the European standard size L2, commonly used in a wide range of passenger cars. The battery comes with the popular B13 mounting type, ensuring compatibility with many European car models.
A notable feature of the Varta D39 is its terminal layout. Unlike most European batteries where the positive terminal is located on the right, this model has the positive terminal on the left (layout 1). This detail is crucial for proper installation, as an incorrect terminal position could cause cable strain or installation problems. Furthermore, the D39 uses standard round terminals (type 1), which are widely compatible with European cars.
When compared to other batteries with similar dimensions, the Varta D39 clearly stands out due to its combination of capacity and starting power. For instance, the Bosch S30 06 offers 56 Ah and 480 A, while the Bosch S40 06 provides 60 Ah and 540 A. Even the Bosch S5 S50 06, which matches the D39 with 63 Ah and 610 A, cannot surpass Varta’s reputation for quality and consistency. Similarly, Exide’s EA601 Premium delivers slightly less capacity at 60 Ah but still offers a high cranking current of 600 A. Meanwhile, Exide’s EB621 and Varta’s own Blue Dynamic D43 deliver slightly less power and capacity compared to the D39, making the Silver Dynamic model the superior choice for drivers looking for maximum performance within these dimensions.
Although the D39 is a powerful conventional battery, it is important to note that it is not designed for cars with start-stop systems. Only EFB (Enhanced Flooded Battery) or AGM (Absorbent Glass Mat) types can effectively handle the demands of start-stop technology. However, for traditional vehicles, the D39 offers unmatched performance, ensuring reliable starts and stable operation of all electronic devices on board. With its premium build quality and technical specifications, the Varta Silver Dynamic D39 remains an outstanding option for discerning drivers.
