In short
- For a Ford C-Max you need a jump starter that covers roughly 460 to 770 CCA, depending on the engine and trim level.
- Your battery has a CCA rating (the cold cranking current, listed as EN on the battery label). A jump starter itself has no CCA: the number shows which battery CCA it covers. Choose a model that covers at least your battery's value.
- For the lighter petrol engines, the Boost Mini 3750 is often enough. For the diesels and the start-stop versions, go for the Boost Pro 8250 (covers up to 960 CCA).
- Below you'll find the right jump starter for each generation and engine variant, from the I (2003) to the II, with the exact battery CCA.
What is CCA and why does it determine your choice?
CCA (Cold Cranking Amps) is the starting power your battery delivers in cold weather. The heavier the engine and the colder it is, the more you need. The value is listed as EN on your battery. A jump starter itself has no CCA: the number shows which battery CCA it covers, so choose a model that matches the EN value of your C-Max. Want the full explanation, the standards (EN, SAE, DIN) and rules of thumb per engine type? Read what CCA actually is and why it determines your choice. Below you'll see which jump starter fits each Ford C-Max engine variant.
