Before ordering the ET550, check this

  • Length, width and height of the ET550: 278 × 175 × 190 mm (European case size L3).
  • Polarity of the ET550: positive terminal on the right (if yours has it on the other side, the cables will not reach).
  • Your current battery should say about 80 Ah; a little more is also fine.
  • Check the EN amps on your battery: if it says 600 A or less, the ET550 covers your engine.
