## What to look at before buying the K8

- Length, width and height of the K8: 513 × 189 × 223 mm.
- Capacity of the K8: 140 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 800 A or less, the K8 covers your engine.

The middle group (400) identifies the specific model within that capacity, and the last three digits (080) multiplied by 10 give the cold cranking current: 800 A.

### How much does the Varta K8 weigh?

The K8 weighs 34.76 kg. For reference, the Varta K7 (145 Ah) weighs 37.12 kg.
