## Where the Kronobat PB-45.1T fits

The Kronobat PB-45.1T is made for petrol and diesel cars without automatic engine stop. If your car has no Start-Stop and had a 45 Ah battery, the PB-45.1T is a direct replacement.
At 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The PB-45.1T belongs to the Kronobat PREMIUM range. [More Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Kronobat PB-45.1T (this one) | 45 Ah | 330 A | 238 × 129 × 227 | left | 11.7 kg |
