## Check this before ordering the Fulmen FB705

- The FB705 needs 270 × 173 × 222 mm of space: measure it with the hold-down clamp in place.
- Polarity of the FB705: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 70 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 540 A or less, the FB705 covers your engine.
- If your car has Start-Stop, the FB705 is not the right one: it needs an EFB or an AGM.

## Lead-acid technology in the FB705

Inside, the FB705 is classic lead-acid: liquid electrolyte and lead plates. If the FB705 is left discharged for weeks it sulphates: a maintenance charger prevents this.
