The Varta Blue Dynamic series represents one of the most popular and reliable lines of automotive batteries in Europe. Known for its high-quality construction, durability, and consistent starting performance, Blue Dynamic batteries are designed for drivers who expect dependable energy every day. These batteries are not equipped with start-stop technology, but they offer excellent cold cranking performance, fast recharge capability, and long service life for vehicles without energy recovery systems. Manufactured using advanced PowerFrame grid technology, Varta Blue Dynamic batteries deliver stable voltage output and reduced corrosion, ensuring reliable operation even under demanding conditions. Their maintenance-free design also means that users can enjoy consistent performance without worrying about topping up electrolyte levels.
The Varta Blue Dynamic E24 is a robust 12V lead-acid battery designed to meet the needs of mid-size cars and light commercial vehicles. With a capacity of 70 Ah and a maximum cold cranking current of 630 A, this battery offers strong starting power even in low temperatures. Its dimensions of 261 mm in length, 175 mm in width, and 220 mm in height suggest that it does not belong to a typical European DIN standard size (such as L0–L6). Instead, its slightly greater height and compact footprint indicate that it follows an Asian form factor, which tends to be taller and narrower. This design makes the E24 suitable for vehicles originally fitted with Asian-type batteries, which often require higher cases to fit into specific compartments.
A notable detail of the Varta E24 is its terminal layout. The battery features layout type 1, which means the positive terminal is positioned on the left side when facing the front of the battery. This is less common in European cars, where the positive pole is usually on the right, but it is typical in many Asian models. Therefore, the Varta E24 is often chosen for Japanese or Korean vehicles where this configuration is standard. The terminal type is also standard (Type 1), ensuring compatibility with most cable connectors used in passenger cars.
The mounting type B01 deserves attention as well. This configuration indicates that the battery has hold-down ledges on the longer sides of the casing, making it less common compared to the more universal B13 mount, which features a retaining ledge around the entire bottom perimeter. The B01 design ensures secure fitting in vehicles designed for this specific mount type, but it may not be directly interchangeable with models using other mounting standards. This means that when replacing an older battery, it’s crucial to ensure the new one matches both the base fixing system and the terminal layout.
In terms of performance and application, the Varta Blue Dynamic E24 can be directly compared to the Bosch S4 S40 27, as both share identical specifications — 70 Ah capacity, 630 A cold cranking power, and the same external dimensions of 261x175x220 mm. Both are standard flooded lead-acid batteries, ideal for conventional vehicles without start-stop systems. However, Varta’s PowerFrame technology often gives the E24 an edge in long-term reliability and corrosion resistance. Drivers looking for dependable starting power, stable energy delivery, and the reassurance of a trusted brand will find the Varta E24 an excellent choice. It combines quality, compatibility, and long service life — a reliable companion for everyday driving needs.
