The Deta DC905 is made for petrol and diesel cars without automatic engine stop. If your car has no Start-Stop and had a 90 Ah battery, the DC905 is a direct replacement.
At 90 Ah it moves into large diesels, SUVs, vans and cars with heavy electrical equipment. The DC905 belongs to the Deta DETA Standard range. [The full range of Deta batteries](https://bateriasonline.es/en/deta-batteries)

- If the positive terminal of your battery is on the other side, the one you need is the Deta DC904 (positive terminal on the right).
- Deta DB955: 5 Ah more, 80 A more cranking power, the same D31 case.

## Equivalents and alternatives to the Deta DC905

Batteries that fit the DC905's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the DC905.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Exide EC905 | Lead-acid | 90 Ah | 680 A | 306 × 173 × 222 |
| Tudor TC905 | Lead-acid | 90 Ah | 680 A | 306 × 173 × 222 |
| Fulmen FC905 | Lead-acid | 90 Ah | 680 A | 306 × 173 × 222 |
| Exide EB955 | Lead-acid | 95 Ah | 760 A | 306 × 173 × 222 |
| Tudor TB955 | Lead-acid | 95 Ah | 760 A | 306 × 173 × 222 |
| Fulmen FB955 | Lead-acid | 95 Ah | 760 A | 306 × 173 × 222 |

## Inside the DC905: lead-acid technology

Inside, the DC905 is classic lead-acid: liquid electrolyte and lead plates. If the DC905 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Before ordering the DC905, check this

- If your car has Start-Stop, the DC905 is not the right one: it needs an EFB or an AGM.
- The DC905 delivers 680 A cold cranking (EN standard); do not go below what your original battery states.
- Your current battery should say about 90 Ah; a little more is also fine.
- Polarity of the DC905: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Measure the space: the DC905 takes up 306 × 173 × 222 mm (European case size D31).

## Frequently asked questions about the Deta DC905

### Deta DC905 or DC904: what is the difference?

Only the polarity: the DC905 has the positive terminal on the left and the DC904 the positive terminal on the right. Capacity (90 Ah), cranking power and dimensions are identical.

### Can the Deta DC905 be used in a car with Start-Stop?

No. The DC905 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### Which battery is equivalent to the Deta DC905?

With the same dimensions, polarity and similar capacity you have the Exide EC905, Tudor TC905 and Fulmen FC905. As the DC905 is a conventional battery, an EFB or AGM of the same size also works.

### Which charger does the Deta DC905 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.
