## Who the Fulmen FA1050 is for

The Fulmen FA1050 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. If your car has no Start-Stop and had a 105 Ah battery, the FA1050 is a direct replacement.
At 105 Ah it is a large battery: vans, 4x4s and vehicles with high electrical demand. The FA1050 belongs to the Fulmen FULMEN Formula Xtreme range. [More Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)

- Polarity of the FA1050: positive terminal on the right (if yours has it on the other side, the cables will not reach).
