## Deta DG1250 vs DF1250, DG1251 and DF1202: which one to choose?

What sets the DG1250 apart from its neighbours in the Deta range:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Deta DG1250 (this one) | 125 Ah | 760 A | 349 × 175 × 285 | right | 29.5 kg |
| Deta DF1250 | 125 Ah | 850 A | 349 × 175 × 285 | right | 31 kg |
| Deta DG1251 | 125 Ah | 760 A | 349 × 175 × 285 | left | 29.5 kg |
| Deta DF1202 | 120 Ah | 870 A | 349 × 175 × 235 | right | 27.5 kg |

- Deta DF1250: the same capacity, 90 A more cranking power, the same dimensions.
- The Deta DG1251 is the same battery with the positive terminal on the other side: choose it if your current battery has the positive terminal on the left.
- Deta DF1202: 5 Ah less, 110 A more cranking power, a different case (349 × 175 × 235 mm).

## 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.
