## Description

## Where the Tudor TB712 fits

The Tudor TB712 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 TB712 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 71 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The TB712 belongs to the Tudor TUDOR TECHNICA range. [See all Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## What to look at before buying the TB712

- The TB712 needs 278 × 175 × 175 mm of space (European case size LB3): measure it with the hold-down clamp in place.
- Polarity of the TB712: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 71 Ah; a little more is also fine.
- Cold cranking: 670 A (EN), equal to or higher than the original.
- If your car has Start-Stop, the TB712 is not the right one: it needs an EFB or an AGM.
