## Description

## The Kronobat PB-40.1F at a glance

The Kronobat PB-40.1F 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. Its job is to start the engine in the cold with margin to spare and keep the car's electronics powered.
At 40 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The PB-40.1F belongs to the Kronobat PREMIUM range. [See all Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)
