The Varta Black Dynamic series is designed primarily for older vehicles and cars with lower energy demands. It stands out for its durability and reliability, offering an economical solution for drivers looking for a good price-to-quality ratio. These batteries use lead-acid technology and are characterized by standard longevity and stable operation in various weather conditions. Their main advantage is high resistance to deep discharge and relatively low electrolyte consumption, ensuring hassle-free use. The Varta Black Dynamic C15 model is a 56 Ah battery with a maximum starting current of 480 A, making it a suitable choice for vehicles with moderate energy needs. Thanks to its advanced technology, it provides a reliable engine start even in more challenging conditions. Its dimensions are 242 x 175 x 190 mm, which places it in the standard European L2 size. This is a common format used in many passenger car models. It is essential to note the terminal layout, marked as 1 in this model. This means that the positive terminal (+) is on the left side, which is a crucial factor when fitting the battery into a specific vehicle. Additionally, the terminal type 1 indicates standard clamps used in most European cars. The B13 mounting zone confirms compatibility with typical fastening systems. Among similar batteries with the same dimensions and comparable specifications, alternative options include Bosch S3 S30 06, Bosch S4 S40 06, Bosch S5 S50 06, Exide Premium EA601, Exide Excell EB621, as well as Varta Blue Dynamic D43 and Varta Silver Dynamic D39.
