## Check this before ordering the Fulmen FB454

- If your car has Start-Stop, the FB454 is not the right one: it needs an EFB or an AGM.
- The FB454 delivers 330 A cold cranking (EN standard); do not go below what your original battery states.
- Capacity of the FB454: 45 Ah; the same as your current battery or slightly more is fine.
- With the terminals facing you, the positive terminal of the FB454 is on the right.
- Measure the space: the FB454 takes up 237 × 127 × 227 mm (European case size B24).
