  • Deta DF1250: the same capacity, 90 A more cranking power, the same dimensions.

Lead-acid technology in the DG1250

Inside, the DG1250 is classic lead-acid: liquid electrolyte and lead plates. If the DG1250 is left discharged for weeks it sulphates: a maintenance charger prevents this.

What to look at before buying the DG1250

  • The DG1250 needs 349 × 175 × 285 mm of space: measure it with the hold-down clamp in place.
  • Polarity of the DG1250: positive terminal on the right (if yours has it on the other side, the cables will not reach).
  • Capacity of the DG1250: 125 Ah; the same as your current battery or slightly more is fine.
  • Check the EN amps on your battery: if it says 760 A or less, the DG1250 covers your engine.
