Where the Fulmen FL604 fits
The Fulmen FL604 is a battery for cars with Start-Stop: it withstands many more starting and partial-discharge cycles than a conventional battery and powers the electronics every time the engine stops at the lights. In a Start-Stop car, the FL604 keeps the radio, climate control and lights running with the engine off without losing capacity.
At 60 Ah it covers petrol compacts and small diesels, the best-selling format in Europe. The FL604 belongs to the Fulmen FULMEN EFB range. See all Fulmen batteries
