## Lead-acid technology in the DA900

Inside, the DA900 is classic lead-acid: liquid electrolyte and lead plates. If the DA900 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Before ordering the DA900, check this

- If your car has Start-Stop, the DA900 is not the right one: it needs an EFB or an AGM.
- Cold cranking: 720 A (EN), equal to or higher than the original.
- Your current battery should say about 90 Ah; a little more is also fine.
- Polarity of the DA900: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Length, width and height of the DA900: 315 × 175 × 190 mm (European case size L4).

## Frequently asked questions about the Deta DA900

### Deta DA900 or DB800?

Compared with the DA900, the Deta DB800 has 10 Ah less and 80 A less cranking power. The DA900 cranks harder; the DB800 is only a good option if your original battery says 640 A or less. Both measure 315 × 175 × 190 mm, so they fit the same tray.

### Can the Deta DA900 be used in a car with Start-Stop?

No. The DA900 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 Deta DK820.

### How much does the Deta DA900 weigh?

The DA900 weighs 19.5 kg. For reference, the Deta DB800 (80 Ah) weighs 19 kg.

### Which battery is equivalent to the Deta DA900?

With the same dimensions, polarity and similar capacity you have the Exide EA900, Tudor TA900 and Fulmen FA900. As the DA900 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Deta DA900?

Case size L4: 315 × 175 × 190 mm. The DA900 fits any standard L4 battery tray such as the Exide EA900.

### Which side is the positive terminal on the Deta DA900?

The DA900 has the positive terminal on the right, looking at the battery from its long side with the terminals closest to you.

### Does the new battery need to be registered in the car?

In cars with energy management (common since 2010) it is worth registering the battery in the control unit so it adjusts charging. In older cars you just connect it.
