## Who the Tudor TB741 is for

The Tudor TB741 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 74 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The TB741 belongs to the Tudor TUDOR TECHNICA range. [The full range of Tudor batteries](https://bateriasonline.es/en/tudor-batteries)
