The Bosch S4 EFB series is designed for vehicles equipped with Start-Stop technology, providing enhanced durability and performance compared to conventional lead-acid batteries. EFB (Enhanced Flooded Battery) technology offers greater resistance to charge and discharge cycles, making it ideal for modern cars that frequently restart the engine at traffic lights and during stop-and-go driving. The Bosch S4 EFB series delivers reliable energy supply to support advanced vehicle electronics, ensuring a stable power source for infotainment systems, climate control, and safety features. These batteries provide excellent cranking power and long service life, making them a dependable choice for everyday driving.
The Bosch S4 E08 is a high-quality EFB battery with a capacity of 70Ah and a cold cranking amperage (CCA) of 650A. This model is specifically engineered for Start-Stop vehicles that require a more durable battery capable of handling frequent engine restarts. The EFB technology enhances cycle life, allowing the battery to perform efficiently under demanding conditions. It is also maintenance-free, eliminating the need for regular water top-ups while ensuring reliable operation.
With dimensions of 278mm in length, 175mm in width, and 190mm in height, the Bosch S4 E08 falls within the L3 battery size category. This is a standard European battery size commonly used in various passenger cars and light commercial vehicles. Its compatibility with the B13 mounting system ensures a secure fit in many vehicle models, making installation straightforward. The standardized terminal layout (0) and terminal type (1) further enhance its ease of use, reducing the risk of compatibility issues.
One of the significant advantages of the Bosch S4 E08 is its ability to maintain a stable voltage output even under high electrical loads. In Start-Stop vehicles, the battery must continuously power essential systems such as lights, sensors, and multimedia features when the engine is off. The EFB construction enhances its ability to recharge quickly and handle deep discharge cycles, extending the overall lifespan compared to traditional lead-acid batteries.
Similar batteries with comparable specifications include the Exide EFB EL700, which offers 70Ah and a higher CCA of 720A, and the Halfords Advanced EFB 096, which provides 75Ah and 700A of starting power. Other alternatives include the Lucas Fusion EFB LE096 and the Varta Blue Dynamic EFB models E45 and N70, both of which share the same dimensions and power characteristics as the Bosch S4 E08. Choosing the right battery depends on vehicle compatibility and specific power requirements.
In conclusion, the Bosch S4 E08 is an excellent choice for vehicles with Start-Stop functionality, offering enhanced durability and reliable performance. Its L3 size, B13 mounting system, and EFB technology make it a highly compatible and efficient option for modern cars. With superior cycle life and strong cranking power, this battery ensures smooth operation and longevity, making it a practical investment for any vehicle requiring a robust and maintenance-free power source.
