## Description

## Who the Deta DB704 is for

The Deta DB704 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. The DB704 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 70 Ah it is the usual size for compact diesels and mid-size petrol saloons. The DB704 belongs to the Deta DETA Power range. [See all Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Before ordering the DB704, check this

- The DB704 needs 270 × 173 × 222 mm of space: measure it with the hold-down clamp in place.
- Polarity of the DB704: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 70 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 540 A or less, the DB704 covers your engine.
- If your car has Start-Stop, the DB704 is not the right one: it needs an EFB or an AGM.

## What it means that the DB704 is lead-acid

The DB704 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.
