What sets the 12N24-4A apart from its neighbours in the Fulbat range:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Fulbat 12N24-4A (this one) | 25.3 Ah | 220 A | 184 × 124 × 175 | left | 7.29 kg |

## Inside the 12N24-4A: lead-acid technology

Inside, the 12N24-4A is classic lead-acid: liquid electrolyte and lead plates. If the 12N24-4A is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Before ordering the 12N24-4A, check this

- Length, width and height of the 12N24-4A: 184 × 124 × 175 mm.
- The 12N24-4A has the positive terminal on the left: compare it with your current battery.
- Your current battery should say about 25.3 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 220 A or less, the 12N24-4A covers your engine.
