|---|---|---|---|---|---|
| Exide AGM12-11 (this one) | 11 Ah | 205 A | 150 × 90 × 110 | left | 4.1 kg |
| Exide ET12A-BS | 10 Ah | 130 A | 150 × 90 × 105 | left | 3.4 kg |
| Exide AGM12-12 | 12 Ah | 200 A | 150 × 90 × 145 | left | 4.5 kg |
| Exide AGM12-12M | 12 Ah | 200 A | 150 × 90 × 145 | left | 4.9 kg |
| Exide AGM12-7.5 | 8 Ah | 120 A | 150 × 90 × 105 | left | 3.1 kg |

- Exide ET12A-BS: 1 Ah less, 75 A less cranking power, a different case (150 × 90 × 105 mm).
- Exide AGM12-12: 1 Ah more, 5 A less cranking power, a different height (145 mm instead of 110 mm). It only fits if there is room for 145 mm of height.
- Exide AGM12-12M: 1 Ah more, 5 A less cranking power, a different height (145 mm instead of 110 mm). It only fits if there is room for 145 mm of height.
- Exide AGM12-7.5: 3 Ah less, 85 A less cranking power, a different case (150 × 90 × 105 mm).

## Before ordering the AGM12-11, check this

- Length, width and height of the AGM12-11: 150 × 90 × 110 mm.
- Polarity of the AGM12-11: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 11 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 205 A or less, the AGM12-11 covers your engine.
