Inside the FK600: AGM technology
The FK600 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.
Check this before ordering the Fulmen FK600
- The FK600 is AGM: it replaces an AGM or an EFB of the same size. You can swap an EFB for an AGM, but not an AGM for an EFB.
- The FK600 delivers 680 A cold cranking (EN standard); do not go below what your original battery states.
- With 60 Ah, the FK600 replaces an original battery of that capacity or slightly less.
- The FK600 has the positive terminal on the right: compare it with your current battery.
- Length, width and height of the FK600: 242 × 175 × 190 mm (European case size L2).
