- 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 AGM12-12.
- 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 AGM12-12.
- Exide AGM12-10: 2 Ah less, 50 A less cranking power, a different case (150 × 90 × 130 mm).

## What to look at before buying the AGM12-12

- Measure the space: the AGM12-12 takes up 150 × 90 × 145 mm.
- The AGM12-12 has the positive terminal on the left: compare it with your current battery.
- With 12 Ah, the AGM12-12 replaces an original battery of that capacity or slightly less.
- Check the EN amps on your battery: if it says 200 A or less, the AGM12-12 covers your engine.
