| Exide AGM12-11 | 11 Ah | 205 A | 150 × 90 × 110 | left | 4.1 kg |
| Exide ETZ14-BS | 11 Ah | 205 A | 150 × 90 × 110 | left | 4.1 kg |
| Exide AGM12-10 | 10 Ah | 150 A | 150 × 90 × 130 | left | 3.9 kg |

- Exide ET14B-BS: the same capacity, 10 A less cranking power, a different case (150 × 70 × 145 mm).
- The Exide AGM12-12.1 is the same battery with the positive terminal on the other side: choose it if your current battery has the positive terminal on the right.
- Exide AGM12-11: 1 Ah less, 5 A more cranking power, a different height (110 mm instead of 145 mm). It is the option if your battery tray cannot take the 145 mm height of the AGM12-12M.
- Exide ETZ14-BS: 1 Ah less, 5 A more cranking power, a different height (110 mm instead of 145 mm). It is the option if your battery tray cannot take the 145 mm height of the AGM12-12M.
- Exide AGM12-10: 2 Ah less, 50 A less cranking power, a different case (150 × 90 × 130 mm).

## Before ordering the AGM12-12M, check this

- Cold cranking: 200 A (EN), equal to or higher than the original.
- With 12 Ah, the AGM12-12M replaces an original battery of that capacity or slightly less.
- With the terminals facing you, the positive terminal of the AGM12-12M is on the left.
- Length, width and height of the AGM12-12M: 150 × 90 × 145 mm.

## Frequently asked questions about the Exide AGM12-12M

### AGM12-12M or ET14B-BS: which one suits me?

Compared with the AGM12-12M, the Exide ET14B-BS has 10 A less cranking power. The AGM12-12M cranks harder; the ET14B-BS is only a good option if your original battery says 190 A or less. Mind the space: the ET14B-BS measures 150 × 70 × 145 mm.

### Exide AGM12-12M or AGM12-12.1: what is the difference?

Only the polarity: the AGM12-12M has the positive terminal on the left and the AGM12-12.1 the positive terminal on the right. Capacity (12 Ah), cranking power and dimensions are identical.

### Exide AGM12-12M or AGM12-11/ETZ14-BS: what changes?

Mainly the height: the AGM12-12M is 145 mm tall and the Exide AGM12-11 110 mm, with the same length and width. In capacity and cranking power, the AGM12-11 offers 11 Ah and 205 A against 12 Ah and 200 A. The Exide ETZ14-BS is 110 mm tall, with 11 Ah and 205 A. Before choosing between the AGM12-12M and the AGM12-11, measure the free height of the battery compartment with the cover or bonnet closed.

### How much does the Exide AGM12-12M weigh?

4.9 kg, with 12 Ah of capacity. For reference, the Exide ET14B-BS (12 Ah) weighs 4.1 kg.

### Which battery is equivalent to the Exide AGM12-12M?

Only other AGM batteries with its dimensions and polarity: Varta YTX14-4 (FA), Fulbat FTX14-BS and Varta YTX14-BS. Neither an EFB nor a conventional battery replaces the AGM12-12M.

## AGM technology in the AGM12-12M

The AGM12-12M is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.
