| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide EF1250 (this one) | 125 Ah | 850 A | 349 × 175 × 285 | right | 31 kg |
| Exide EG1250 | 125 Ah | 760 A | 349 × 175 × 285 | right | 29.5 kg |

| Exide EF1202 | 120 Ah | 870 A | 349 × 175 × 235 | right | 27.5 kg |
| Exide EF1420 | 142 Ah | 850 A | 349 × 175 × 290 | right | 35.1 kg |

- Exide EG1250: the same capacity, 90 A less cranking power, the same dimensions.
- Exide EF1251: identical to the EF1250 except for the positive terminal, which is on the other side (positive terminal on the left).
- Exide EF1202: 5 Ah less, 20 A more cranking power, a different height (235 mm instead of 285 mm). It is the option if your battery tray cannot take the 285 mm height of the EF1250.
- Exide EF1420: 17 Ah more, the same cranking power, a different case (349 × 175 × 290 mm).

## Inside the EF1250: lead-acid technology

The EF1250 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.

## Check this before ordering the Exide EF1250

- Length, width and height of the EF1250: 349 × 175 × 285 mm.
- The EF1250 has the positive terminal on the right: compare it with your current battery.
