Choosing the right battery for a 2018 Ford Focus Mk4 with a Start-Stop system depends on the engine type and its parameters. For most cases, an EFB (Enhanced Flooded Battery) is recommended due to its higher resistance to frequent discharges, which is crucial for vehicles with Start-Stop systems. The key parameters to consider are the battery’s capacity and cold cranking amperes (CCA). For most engine versions, the minimum capacity is 65 Ah, and the CCA is 650 A. Exceptions include the more powerful 2.0 EcoBlue engines, requiring a capacity of 70–75 Ah and a CCA of up to 760 A.
Examples of suitable battery models include Bosch S4 E07, Exide EL652, and Varta D54 for smaller engines, while Bosch S4 E08, Exide EL700, or Varta E45 are suitable for the 2.0 EcoBlue engines. It is essential to note that the battery height in the Ford Focus Mk4 should not exceed 175 mm, which might limit your options. If in doubt, consult manufacturers’ catalogs to ensure compatibility with your vehicle.
Interestingly, EFB batteries are a relatively new solution, designed as a compromise between traditional lead-acid batteries and more advanced, expensive AGM batteries. This means they are more affordable while still offering good performance and durability. Additionally, consider the operating conditions of your vehicle – if you frequently drive in cold climates, choose a battery with a higher CCA to make starting the engine easier.
Remember, selecting the right battery is an investment that ensures your car’s reliability in daily use. Pay attention not only to technical specifications but also to the manufacturer’s reputation and warranty provided.
