## Exide 4901 vs U1-9 and 49900(U1R-250): which one to choose?

The real differences between the 4901 and the closest Exide models:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide 4901 (this one) | 24 Ah | 250 A | 197 × 132 × 186 | left | 7.9 kg |
| Exide U1-9 | 24 Ah | 240 A | 195 × 130 × 180 | left | 8.3 kg |
| Exide 49900(U1R-250) | 24 Ah | 250 A | 197 × 132 × 186 | right | 7.9 kg |

- Exide U1-9: the same capacity, 10 A less cranking power, a different case (195 × 130 × 180 mm).
- Exide 49900(U1R-250): identical to the 4901 except for the positive terminal, which is on the other side (positive terminal on the right).

## What it means that the 4901 is lead-acid

Inside, the 4901 is classic lead-acid: liquid electrolyte and lead plates. If the 4901 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Before ordering the 4901, check this

- The 4901 needs 197 × 132 × 186 mm of space: measure it with the hold-down clamp in place.
- The 4901 has the positive terminal on the left: compare it with your current battery.
- Your current battery should say about 24 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 250 A or less, the 4901 covers your engine.
