The Hyundai i40 CW (station wagon) debuted in 2011 as a stylish and spacious family car, combining modern design with functionality. Choosing the right battery for this model depends on the engine version and the systems installed in the vehicle.
For gasoline versions with 1.6 GDI and 2.0 GDI engines, lead-acid batteries with a capacity of 60 to 65 Ah and a cold cranking current of 540–640 A are recommended. Suitable example models include Bosch S40 05, Bosch S50 05, Exide EA640, Exide EB620, Halfords HCB 027, Lucas LS027, Varta D15, and Varta D24. These batteries are reliable and well-suited for vehicles without the Start-Stop system.
For the 1.7 CRDi diesel version equipped with the Start-Stop system, more advanced AGM (Absorbent Glass Mat) batteries are required. If the battery capacity is 70 to 72 Ah and the cold cranking current ranges between 720 and 760 A, models such as Bosch S5A 08, Exide EK700, Exide EK720, Halfords AGM 096, Lucas LF096, or Varta E39 are suitable. For higher capacity (80–82 Ah) and a cranking current of 800 A, appropriate batteries include Bosch S5A 11, Exide EK800, Exide EK820, Halfords AGM 115, Lucas LF115, and Varta F21.
Interestingly, the Hyundai i40 CW was designed with European users in mind, offering a spacious interior and a large trunk capacity – ideal for families and frequent travelers. A properly selected battery will not only ensure smooth operation of all vehicle systems but also provide reliability in all weather conditions.
