Before ordering the FJ1000, check this

  • The FJ1000 needs 353 × 175 × 190 mm of space (European case size L5): measure it with the hold-down clamp in place.
  • Polarity of the FJ1000: positive terminal on the right (if yours has it on the other side, the cables will not reach).
  • With 100 Ah, the FJ1000 replaces an original battery of that capacity or slightly less.
  • Check the EN amps on your battery: if it says 850 A or less, the FJ1000 covers your engine.
