Inside the FG1203: lead-acid technology
Inside, the FG1203 is classic lead-acid: liquid electrolyte and lead plates. If the FG1203 is left discharged for weeks it sulphates: a maintenance charger prevents this.
Before ordering the FG1203, check this
- The FG1203 needs 513 × 189 × 223 mm of space: measure it with the hold-down clamp in place.
- With 120 Ah, the FG1203 replaces an original battery of that capacity or slightly less.
- The FG1203 delivers 680 A cold cranking (EN standard); do not go below what your original battery states.

Which battery is equivalent to the Fulmen FG1203?
With the same dimensions, polarity and similar capacity you have the Exide EG1203, Varta I8 and Tudor TG1203. As the FG1203 is a conventional battery, an EFB or AGM of the same size also works.
Are truck batteries fitted in pairs?
Almost always, in series for 24 V. Replace them in matched pairs: mixing a new one with an old one unbalances charging and shortens the new one's life.
