## What to look at before buying the DA640

- The DA640 needs 242 × 175 × 190 mm of space (European case size L2): measure it with the hold-down clamp in place.
- Polarity of the DA640: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 64 Ah; a little more is also fine.
- Cold cranking: 640 A (EN), equal to or higher than the original.
- If your car has Start-Stop, the DA640 is not the right one: it needs an EFB or an AGM.

## Lead-acid technology in the DA640

Inside, the DA640 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## Frequently asked questions about the Deta DA640

### DA640 or DB620: which one suits me?

Compared with the DA640, the Deta DB620 has 2 Ah less and 100 A less cranking power. The DA640 cranks harder; the DB620 is only a good option if your original battery says 540 A or less. Both measure 242 × 175 × 190 mm, so they fit the same tray.

### Deta DA640 or DA612: what changes?

Mainly the height: the DA640 is 190 mm tall (L2) and the Deta DA612 175 mm (LB2), with the same length and width. In capacity and cranking power, the DA612 offers 61 Ah and 600 A against 64 Ah and 640 A. Before choosing between the DA640 and the DA612, measure the free height of the battery compartment with the cover or bonnet closed.

### Can the Deta DA640 be used in a car with Start-Stop?

No. The DA640 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM; in this same size there is the Exide EK620.

### How much does the Deta DA640 weigh?

14.9 kg, with 64 Ah of capacity. For reference, the Deta DB620 (62 Ah) weighs 13.9 kg.

### Which battery is equivalent to the Deta DA640?

With the same dimensions, polarity and similar capacity you have the Exide EA640, Tudor TA640 and Fulmen FA640. As the DA640 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Deta DA640?

Case size L2: 242 × 175 × 190 mm. The DA640 fits any standard L2 battery tray such as the Exide EA640.

### Which side is the positive terminal on the Deta DA640?

On the DA640, the positive terminal is on the right with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.
