## Description

## Who the Tudor TB558 is for

The Tudor TB558 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 TB558 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 55 Ah it covers petrol compacts and small diesels, the best-selling format in Europe. The TB558 belongs to the Tudor TUDOR TECHNICA range. [More Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## Check this before ordering the Tudor TB558

- The TB558 needs 230 × 180 × 186 mm of space: measure it with the hold-down clamp in place.
- Polarity of the TB558: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 55 Ah; a little more is also fine.
- The TB558 delivers 620 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the TB558 is not the right one: it needs an EFB or an AGM.

## Inside the TB558: lead-acid technology

The TB558 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
