The Exide AGM battery series represents one of the most advanced solutions for vehicles equipped with modern energy management systems, including advanced start-stop functionality and regenerative braking. AGM, which stands for Absorbent Glass Mat, is a technology that enhances performance and longevity by encapsulating the electrolyte in fiberglass separators. This design significantly improves resistance to vibration, supports rapid charging, and allows the battery to withstand frequent charge and discharge cycles—making it ideal for cars with high electrical demands or frequent urban driving.
The Exide EK508 is a high-performance battery from this premium AGM series, offering a 50Ah capacity and an impressive cold cranking power of 800A, which is remarkable for a battery of this size. This powerful starting capability makes the EK508 suitable not just for small cars but also for vehicles with energy-demanding accessories like heated seats, infotainment systems, or auxiliary heaters. Despite its relatively modest capacity, the high cranking amperage ensures reliable engine starts even in extreme weather conditions.
With dimensions of 260 mm in length, 173 mm in width, and 206 mm in height, the EK508 closely matches the D26 size category, which is commonly found in vehicles requiring slightly larger battery footprints, particularly among Asian manufacturers. Its slightly elevated height and narrower width suggest a more vertically compact yet dense design, optimized for performance in tighter engine bays. This form factor ensures both installation flexibility and high power density.
The EK508 features terminal layout 9, indicating that the positive terminal is located front right when viewed from above—an arrangement less common in Europe but often found in Japanese or Korean vehicles. It’s essential for users to match this layout during replacement to avoid issues with cable reach or polarity. The battery uses type 1 standard terminals, compatible with the majority of passenger cars.
A distinctive feature of the EK508 is its B7 base hold-down configuration. Unlike the widely used B13 or B1 types, B7 offers unique mounting properties, often relying on side rails or custom mounts within specific vehicle platforms. While this makes the battery less universal in terms of installation, it ensures a secure fit in vehicles explicitly designed for it—common in certain premium or commercial applications.
As an AGM battery, the EK508 is specifically designed for start-stop systems, where engine restarts and fluctuating loads are frequent. This battery excels in maintaining a consistent voltage under load, supporting not only the starter motor but also other critical systems during engine-off phases in traffic. AGM also guarantees a spill-proof design, enhanced cycle life, and better performance in both hot and cold climates.
In conclusion, the Exide EK508 is an advanced, high-output battery built for vehicles that demand more than what traditional lead-acid designs can offer. With its robust AGM construction, impressive starting power, and compatibility with modern systems, it’s a smart investment for drivers prioritizing reliability, efficiency, and long service life.

The Exide EK508 is an advanced car battery designed specifically for modern vehicles, particularly those from the Asian market. Batteries of this size are frequently installed in cars from Asian brands such as Toyota, Honda, Nissan, Mazda, Subaru, or Mitsubishi, which often have different requirements for battery dimensions and mounting methods compared to European cars.
AGM Technology – A Modern Solution
The Exide EK508 utilizes AGM (Absorbent Glass Mat) technology, one of the most advanced technologies used in lead-acid batteries. In AGM technology, the electrolyte is absorbed by special fiberglass mats, preventing leakage and increasing operational safety. Thanks to AGM technology, the battery is more resistant to deep discharges and can handle a greater number of charge and discharge cycles. This is especially important for vehicles equipped with start-stop systems that require frequent engine starts.
Technical Specifications and Performance
The Exide EK508 features a capacity of 50 Ah and a starting current of 800 A. These specifications ensure reliable engine starting even under challenging weather conditions, which is particularly crucial during the winter months. The battery dimensions are: length 260 mm, width 173 mm, and height 200 mm. These compact dimensions are typical for Asian vehicles, which usually have smaller engine compartments and require batteries with specific sizes and mounts.
Mounting Specifics in Asian Vehicles
Unlike many European models, vehicles from Asia often have different requirements for battery dimensions and mounting methods. In such vehicles, batteries need to be compact but still provide high performance and reliability. The Exide EK508 has been designed to meet these requirements, making it the ideal choice for owners of Asian vehicles who need a battery with the appropriate dimensions and specifications.
Durability and Environmental Friendliness
Thanks to AGM technology, the Exide EK508 offers not only high performance but also a longer lifespan. This means that the battery needs to be replaced less frequently, leading to lower operating costs and reduced environmental impact. Additionally, the battery’s efficient energy management supports fuel savings and contributes to reducing CO2 emissions, which is important both from an ecological and economic perspective.
Conclusion
The Exide EK508 is a modern car battery that perfectly fits vehicles of Asian origin. With AGM technology, a capacity of 50 Ah, and a starting current of 800 A, it provides reliable starting and long life while meeting the specific size and mounting requirements of many Asian models. It is the ideal choice for car owners who expect a durable and high-performance solution.
