Who the Fulmen FB440 is for

The Fulmen FB440 is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. The FB440 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.

At 44 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The FB440 belongs to the Fulmen FULMEN Formula range. The full range of Fulmen batteries

  • Cold cranking: 400 A (EN), equal to or higher than the original.
  • Capacity of the FB440: 44 Ah; the same as your current battery or slightly more is fine.
  • Polarity of the FB440: positive terminal on the right (if yours has it on the other side, the cables will not reach).
  • The FB440 needs 175 × 175 × 190 mm of space (European case size L0): measure it with the hold-down clamp in place.
