## Where the Deta DB440 fits

The Deta DB440 is made for petrol and diesel cars without automatic engine stop. Its job is to start the engine in the cold with margin to spare and keep the car's electronics powered.
At 44 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The DB440 belongs to the Deta DETA Power range. [The full range of Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Before ordering the DB440, check this

- Measure the space: the DB440 takes up 175 × 175 × 190 mm (European case size L0).
- Polarity of the DB440: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 44 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 400 A or less, the DB440 covers your engine.
- If your car has Start-Stop, the DB440 is not the right one: it needs an EFB or an AGM.

## Lead-acid technology in the DB440

Inside, the DB440 is classic lead-acid: liquid electrolyte and lead plates. If the DB440 is left discharged for weeks it sulphates: a maintenance charger prevents this.
