Check this before ordering the Fulmen FK700
- The FK700 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.
- Check the EN amps on your battery: if it says 760 A or less, the FK700 covers your engine.
- With 70 Ah, the FK700 replaces an original battery of that capacity or slightly less.
- With the terminals facing you, the positive terminal of the FK700 is on the right.
- The FK700 needs 278 × 175 × 190 mm of space (European case size L3): measure it with the hold-down clamp in place.
