## Description

## Who the Fulmen FB500 is for

The Fulmen FB500 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 FB500 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 50 Ah it covers petrol compacts and small diesels, the best-selling format in Europe. The FB500 belongs to the Fulmen FULMEN Formula range. [See all Fulmen batteries](https://bateriasonline.es/en/fulmen-batteries)
