## Exide ETX12-BS vs AGM12-10.5, ETZ10-BS and AGM12-8

Torn between the ETX12-BS and another similar Exide? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide ETX12-BS (this one) | 10 Ah | 150 A | 150 × 90 × 130 | left | 3.9 kg |
| Exide AGM12-10.5 | 10 Ah | 160 A | 150 × 70 × 130 | left | 3.6 kg |
| Exide ETZ10-BS | 9 Ah | 145 A | 150 × 90 × 95 | left | 3.4 kg |
| Exide AGM12-8 | 8.6 Ah | 145 A | 150 × 90 × 95 | left | 3.4 kg |
| Exide ET12B-BS | 10 Ah | 160 A | 150 × 70 × 130 | left | 3.7 kg |

- Exide AGM12-10.5: the same capacity, 10 A more cranking power, a different case (150 × 70 × 130 mm).
- Exide ETZ10-BS: 1 Ah less, 5 A less cranking power, a different height (95 mm instead of 130 mm). It is the option if your battery tray cannot take the 130 mm height of the ETX12-BS.
- Exide AGM12-8: 1.40 Ah less, 5 A less cranking power, a different height (95 mm instead of 130 mm). It is the option if your battery tray cannot take the 130 mm height of the ETX12-BS.
- Exide ET12B-BS: the same capacity, 10 A more cranking power, a different case (150 × 70 × 130 mm).

## Check this before ordering the Exide ETX12-BS

- Measure the space: the ETX12-BS takes up 150 × 90 × 130 mm.
- The ETX12-BS has the positive terminal on the left: compare it with your current battery.
- Capacity of the ETX12-BS: 10 Ah; the same as your current battery or slightly more is fine.
- Cold cranking: 150 A (EN), equal to or higher than the original.
