In short
- For an Audi A1 you need the Boost Pro 8250, regardless of the engine. Even the lighter versions have a battery with a high cold cranking current (around 570 to 840 CCA).
- Your battery has a CCA value (the cold cranking current, listed 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 the value of your battery.
- For every A1, the Boost Pro 8250 (suitable up to 960 CCA) is the right choice. The lighter models are too light for these batteries.
- Below you'll find the right jump starter per generation and engine variant, from the 8X (2010) to the GB, 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 the cold. 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 up to which battery CCA it's suitable, so choose a model that matches the EN value of your A1. 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 Audi A1 engine variant.
