In short
- For a BMW 2 Series Active Tourer or Gran Tourer you need a jump starter suitable up to roughly 640 to 840 CCA, depending on the engine.
- Your battery has a CCA value (the cold cranking current, shown as EN on the battery label). A jump starter itself has no CCA: the number shows up to which battery CCA it's suitable. Choose a model that's suitable up to at least your battery's value.
- Almost every version has a battery with a high cold cranking current. For petrol, diesel and the 225xe plug-in, choose the Boost Pro 8250.
- Below you'll find the right jump starter per engine variant for the 2 Series Active Tourer and Gran Tourer (from 2014).
What is CCA and why does it determine your choice?
CCA (Cold Cranking Amps) is the starting power your battery delivers in the cold. The heavier the engine and the colder it is, the more you need. The value is shown as EN on your battery. A jump starter itself has no CCA: the number shows up to which battery CCA it's suitable, so choose a model that matches the EN value of your 2 Series Active Tourer. 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 is suitable per engine variant.
