## Description

## Who the Tudor TB704 is for

The Tudor TB704 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 70 Ah it is the usual size for compact diesels and mid-size petrol saloons. The TB704 belongs to the Tudor TUDOR TECHNICA range. [See all Tudor batteries](https://bateriasonline.es/en/tudor-batteries)
