In short
- For a Mercedes B-Class you need a jump starter suitable up to about 620 to 850 CCA, depending on the engine and generation.
- 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 suitable up to at least the value of your battery.
- Almost every B-Class has a battery with a high cold cranking current. For petrol (B 160 to B 250), CDI diesel and the mild hybrid versions, choose the Boost Pro 8250.
- Below you'll find the right jump starter for each generation and engine variant, from the B-Class W245 (2005) to the current W247.
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 B-Class. Want the full explanation, the standards (EN, SAE, DIN) and rules of thumb per engine type? Read what CCA is exactly and why it determines your choice. Below you'll see which jump starter is suitable for each Mercedes B-Class generation and engine variant.
