## Description

## The Deta DB457 at a glance

The Deta DB457 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. If your car has no Start-Stop and had a 45 Ah battery, the DB457 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 DB457 belongs to the Deta DETA Power range. [See all Deta batteries](https://bateriasonline.es/en/deta-batteries)
