## Description

## Where the Deta DB558 fits

The Deta DB558 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 55 Ah it covers petrol compacts and small diesels, the best-selling format in Europe. The DB558 belongs to the Deta DETA Power range. [More Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Check this before ordering the Deta DB558

- Measure the space: the DB558 takes up 230 × 180 × 186 mm.
- With the terminals facing you, the positive terminal of the DB558 is on the left.
- Your current battery should say about 55 Ah; a little more is also fine.
- The DB558 delivers 620 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the DB558 is not the right one: it needs an EFB or an AGM.

## Inside the DB558: lead-acid technology

The DB558 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.

## Frequently asked questions about the Deta DB558

### DB558 or DB621: which one suits me?

Compared with the DB558, the Deta DB621 has 7 Ah more and 80 A less cranking power. The DB558 cranks harder; the DB621 is only a good option if your original battery says 540 A or less. Mind the space: the DB621 measures 242 × 175 × 190 mm.

### Can the Deta DB558 be used in a car with Start-Stop?

No. The DB558 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Deta DB558 weigh?

14.2 kg, with 55 Ah of capacity. For reference, the Deta DB621 (62 Ah) weighs 14.4 kg.

### Which battery is equivalent to the Deta DB558?

With the same dimensions, polarity and similar capacity you have the Exide EB558 and Tudor TB558. As the DB558 is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Deta DB558?

On the DB558, the positive terminal is on the left with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

### Which charger does the Deta DB558 need?

An automatic lead-acid charger with cut-off or maintenance mode, rated at 10 to 20% of its capacity in amps. If it is a vented type, check the electrolyte level and top up only with distilled water.
