## Check this before ordering the Fulmen FB320

- The FB320 needs 178 × 135 × 225 mm of space: measure it with the hold-down clamp in place.
- The FB320 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 32 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 270 A or less, the FB320 covers your engine.
- If your car has Start-Stop, the FB320 is not the right one: it needs an EFB or an AGM.

## Inside the FB320: lead-acid technology

Inside, the FB320 is classic lead-acid: liquid electrolyte and lead plates. If the FB320 is left discharged for weeks it sulphates: a maintenance charger prevents this.
