What to look at before buying the FB620

  • Length, width and height of the FB620: 242 × 175 × 190 mm (European case size L2).
  • Polarity of the FB620: positive terminal on the right (if yours has it on the other side, the cables will not reach).
  • Capacity of the FB620: 62 Ah; the same as your current battery or slightly more is fine.
  • Check the EN amps on your battery: if it says 540 A or less, the FB620 covers your engine.
  • If your car has Start-Stop, the FB620 is not the right one: it needs an EFB or an AGM.

Inside the FB620: lead-acid technology

Inside, the FB620 is classic lead-acid: liquid electrolyte and lead plates. If the FB620 is left discharged for weeks it sulphates: a maintenance charger prevents this.
