## Description

## The Kronobat PB-40.0F at a glance

The Kronobat PB-40.0F is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. The PB-40.0F covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 40 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The PB-40.0F belongs to the Kronobat PREMIUM range. [The full range of Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)

## Inside the PB-40.0F: lead-acid technology

- Cold cranking: 330 A (EN), equal to or higher than the original.
- Capacity of the PB-40.0F: 40 Ah; the same as your current battery or slightly more is fine.
- Polarity of the PB-40.0F: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the PB-40.0F takes up 187 × 127 × 227 mm (European case size B19).
