## Quick description

The Deta DB705 is a car battery with 12 V, 70 Ah and 540 A cold cranking current, measuring 270 × 173 × 222 mm, with the positive terminal on the left. Need the positive terminal on the right? The same battery is the Deta DB704.

## Description

## Where the Deta DB705 fits

The Deta DB705 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. If your car has no Start-Stop and had a 70 Ah battery, the DB705 is a direct replacement.
At 70 Ah it is the usual size for compact diesels and mid-size petrol saloons. The DB705 belongs to the Deta DETA Power range. [See all Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Deta DB705 vs DA755, DB704 and DK508

Torn between the DB705 and another similar Deta? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Deta DB705 (this one) | 70 Ah | 540 A | 270 × 173 × 222 | left | 16.1 kg |

| Deta DK508 | 50 Ah | 800 A | 260 × 173 × 206 | – | 17.5 kg |

- Deta DA755: 5 Ah more, 90 A more cranking power, the same dimensions.
- If the positive terminal of your battery is on the other side, the one you need is the Deta DB704 (positive terminal on the right).
- Deta DK508: 20 Ah less, 260 A more cranking power, a different case (260 × 173 × 206 mm), AGM technology.

## Equivalents and alternatives to the Deta DB705

Batteries that fit the DB705's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the DB705.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Exide EB705 | Lead-acid | 70 Ah | 540 A | 270 × 173 × 222 |
| Tudor TB705 | Lead-acid | 70 Ah | 540 A | 270 × 173 × 222 |
| Fulmen FB705 | Lead-acid | 70 Ah | 540 A | 270 × 173 × 222 |

## What it means that the DB705 is lead-acid

The DB705 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the DB705 needs no special registration: just connect it.

## Check this before ordering the Deta DB705

- If your car has Start-Stop, the DB705 is not the right one: it needs an EFB or an AGM.
- Cold cranking: 540 A (EN), equal to or higher than the original.
- Capacity of the DB705: 70 Ah; the same as your current battery or slightly more is fine.
- With the terminals facing you, the positive terminal of the DB705 is on the left.
- The DB705 needs 270 × 173 × 222 mm of space: measure it with the hold-down clamp in place.

## Frequently asked questions about the Deta DB705

### DB705 or DA755: which one suits me?

Compared with the DB705, the Deta DA755 has 5 Ah more and 90 A more cranking power. If your current battery says 630 A or more, choose the DA755; if it says 540 A or less, the DB705 is enough. Both measure 270 × 173 × 222 mm, so they fit the same tray.

### Deta DB705 or DB704: what is the difference?

Only the polarity: the DB705 has the positive terminal on the left and the DB704 the positive terminal on the right. Capacity (70 Ah), cranking power and dimensions are identical.

### Can the Deta DB705 be used in a car with Start-Stop?

No. The DB705 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 DK508.

### How much does the Deta DB705 weigh?

16.1 kg, with 70 Ah of capacity. For reference, the Deta DA755 (75 Ah) weighs 17.4 kg.

### Which battery is equivalent to the Deta DB705?

With the same dimensions, polarity and similar capacity you have the Exide EB705, Tudor TB705 and Fulmen FB705. As the DB705 is a conventional battery, an EFB or AGM of the same size also works.

### 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.
