The Exide EFB series is a technologically advanced battery line developed to meet the growing demands of modern vehicles equipped with start-stop systems. EFB, or Enhanced Flooded Battery, technology offers improved charge acceptance and longer cycle life compared to traditional flooded batteries. This makes it particularly effective in vehicles that frequently start and stop in traffic, use regenerative braking, or support multiple electrical systems. Exide’s EFB batteries are designed for durability under partial state-of-charge conditions, delivering stable performance even in demanding urban environments. They serve as an efficient and cost-effective alternative to AGM batteries for mid-range start-stop applications.
The Exide EL604 is a compact yet powerful model in the EFB lineup, delivering 60 Ah of capacity and 520 A of cold cranking power. This makes it well-suited for small to medium-sized passenger cars with start-stop technology. Its performance ensures reliable engine starts, consistent voltage output, and efficient energy recovery during braking. It’s particularly ideal for drivers navigating city streets where frequent engine shutdowns and restarts put significant strain on conventional batteries.
Measuring 230 mm in length, 173 mm in width, and 222 mm in height, the EL604 closely corresponds to the D23 battery size, a format commonly found in European and Japanese vehicles. Its dimensions indicate compatibility with compact battery trays that still require a battery capable of high cyclic resistance and solid cold-start capabilities. The height and shape also suggest a form factor more commonly associated with Asian-style batteries, which are generally taller and narrower than European ones. This ensures that the EL604 can be fitted into vehicles with vertically limited engine bays without sacrificing performance.
One important detail of the EL604 is its B0 mounting type, meaning the battery does not feature a bottom ledge for traditional clamp-down mounts. This design is less common in European vehicles, where B13 is standard, but is frequently used in Japanese and Korean cars. It’s crucial to verify vehicle compatibility, as B0 batteries require a battery tray or securing mechanism specifically designed to hold smooth-bottom units. If your vehicle is equipped to accept a B0 battery, the EL604 is an ideal fit both dimensionally and electrically.
The EL604 also comes with terminal layout 0 and terminal type 1, which refers to standard European post layout and sizes, making installation simple and compatible with most vehicle wiring systems. This model compares well to competitors such as the Varta Blue Dynamic EFB N65, which offers slightly more capacity (65 Ah) and a stronger cranking current (650 A), but the Exide EL604 provides excellent performance in a slightly more compact form, making it a better fit for vehicles with tighter battery compartments.
In conclusion, the Exide EL604 is an efficient and compact EFB battery built to support vehicles with modern energy demands and start-stop systems. Its strong cycling performance, excellent charge acceptance, and compatibility with compact battery spaces make it a smart choice for drivers seeking reliable performance in dense traffic environments. With its D23-like dimensions, smooth B0 base, and trusted Exide build quality, the EL604 is a dependable and well-matched solution for a wide range of modern vehicles.
