## Description

## Who the Deta DC400 is for

The Deta DC400 is made for petrol and diesel cars without automatic engine stop. If your car has no Start-Stop and had a 40 Ah battery, the DC400 is a direct replacement.
At 40 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The DC400 belongs to the Deta DETA Standard range. [See all Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Lead-acid technology in the DC400

Inside, the DC400 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.

## Before ordering the DC400, check this

- If your car has Start-Stop, the DC400 is not the right one: it needs an EFB or an AGM.
- The DC400 delivers 320 A cold cranking (EN standard); do not go below what your original battery states.
- With 40 Ah, the DC400 replaces an original battery of that capacity or slightly less.
- The DC400 has the positive terminal on the right: compare it with your current battery.
- Measure the space: the DC400 takes up 175 × 175 × 190 mm (European case size L0).

## Frequently asked questions about the Deta DC400

### DC400 or DB440: which one suits me?

Compared with the DC400, the Deta DB440 has 4 Ah more and 80 A more cranking power. If your current battery says 400 A or more, choose the DB440; if it says 320 A or less, the DC400 is enough. Both measure 175 × 175 × 190 mm, so they fit the same tray.

### Can the Deta DC400 be used in a car with Start-Stop?

No. The DC400 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Deta DC400 weigh?

10.4 kg, with 40 Ah of capacity. For reference, the Deta DB440 (44 Ah) weighs 10.7 kg.

### Which battery is equivalent to the Deta DC400?

With the same dimensions, polarity and similar capacity you have the Exide EC400, Tudor TC400 and Fulmen FC400. As the DC400 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Deta DC400?

Case size L0: 175 × 175 × 190 mm. The DC400 fits any standard L0 battery tray such as the Exide EC400.

### Which side is the positive terminal on the Deta DC400?

On the DC400, 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.

### Which charger does the Deta DC400 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.
