## Description

## The Kronobat PB-45.0T at a glance

The Kronobat PB-45.0T 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-45.0T covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The PB-45.0T belongs to the Kronobat PREMIUM range. [More Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)
