## Where the Deta DB800 fits

The Deta DB800 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 80 Ah battery, the DB800 is a direct replacement.
At 80 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The DB800 belongs to the Deta DETA Power range. [The full range of Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Check this before ordering the Deta DB800

- Measure the space: the DB800 takes up 315 × 175 × 190 mm (European case size L4).
- With the terminals facing you, the positive terminal of the DB800 is on the right.
- Your current battery should say about 80 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 640 A or less, the DB800 covers your engine.
- If your car has Start-Stop, the DB800 is not the right one: it needs an EFB or an AGM.

## Inside the DB800: lead-acid technology

The DB800 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
