The Citroën C4 is one of the key models from the French manufacturer, which has undergone significant changes over the years, both in terms of design and technology. The first generation, known as the Citroën C4 I, debuted in 2004 and quickly gained popularity thanks to its distinctive styling and driving comfort. It stood out with its modern, aerodynamic body and a uniquely designed interior. The vehicle was also praised for its high safety standards and rich equipment options.


In 2010, the second generation of the Citroën C4 was introduced, known by its B7 designation. The car underwent a stylistic evolution, gaining a more elegant appearance and higher quality interior materials. The Citroën C4 II B7 also brought in modern technological solutions, such as the Start-Stop system, which improved fuel efficiency and reduced emissions, helping the model meet increasingly strict environmental regulations.


When it comes to battery requirements, the Citroën C4 had different needs depending on the version and technology used. The first-generation models and the second generation without the Start-Stop system used standard lead-acid batteries. For these versions, batteries with capacities ranging from 44 Ah up to 78 Ah and cold cranking amps (CCA) from 360 to 780 A were recommended. This wide range of requirements reflects the variety of engine options available—ranging from less demanding petrol engines to more power-intensive diesel units that required greater energy reserves, especially in cold weather conditions.


In contrast, the second-generation C4 equipped with the Start-Stop system required AGM (Absorbent Glass Mat) batteries. AGM technology is essential for vehicles with Start-Stop functionality, as these batteries are better suited to frequent charge and discharge cycles and provide consistent starting power. In the case of the Citroën C4 II B7 with Start-Stop, the recommended battery capacity was between 70 and 72 Ah, with required starting currents ranging from 720 to 760 A.


In summary, choosing the right battery for the Citroën C4 depends primarily on the vehicle’s generation and whether it is equipped with the Start-Stop system. For models without this system, standard lead-acid batteries with a wide range of specifications are suitable, while modern versions with Start-Stop require specialized AGM batteries designed to withstand intensive operating conditions. Selecting the appropriate battery ensures the vehicle remains reliable and comfortable to use on a daily basis.
