| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta YTX14-BS (this one) | 12 Ah | 200 A | 152 × 88 × 147 | left | 4.37 kg |
| Varta T14B-BS | 12 Ah | 190 A | 152 × 70 × 145 | left | 4.11 kg |

| Varta TX14H (FA) | 16 Ah | 240 A | 150 × 88.5 × 145 | left | 5.4 kg |

- Varta T14B-BS: the same capacity, 10 A less cranking power, a different case (152 × 70 × 145 mm).
- Varta TZ12S (FA): 1 Ah less, 10 A more cranking power, a different height (110 mm instead of 147 mm). It is the option if your battery tray cannot take the 147 mm height of the YTX14-BS.
- Varta TZ14S (FA): 1 Ah less, 20 A more cranking power, a different height (110 mm instead of 147 mm). It is the option if your battery tray cannot take the 147 mm height of the YTX14-BS.
- Varta TX14H (FA): 4 Ah more, 40 A more cranking power, the same dimensions.

## What to look at before buying the YTX14-BS

- The YTX14-BS needs 152 × 88 × 147 mm of space: measure it with the hold-down clamp in place.
- The YTX14-BS has the positive terminal on the left: compare it with your current battery.
- With 12 Ah, the YTX14-BS replaces an original battery of that capacity or slightly less.
- The YTX14-BS delivers 200 A cold cranking (EN standard); do not go below what your original battery states.
