## The Deta DB621 at a glance

The Deta DB621 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 62 Ah it is the usual size for compact diesels and mid-size petrol saloons. The DB621 belongs to the Deta DETA Power range. [See all Deta batteries](https://bateriasonline.es/en/deta-batteries)
