## Quick description

Deta DB357: car battery with 12 V, 35 Ah and 240 A cold cranking current, measuring 187 × 127 × 220 mm.

## Description

## Where the Deta DB357 fits

The Deta DB357 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. Its job is to start the engine in the cold with margin to spare and keep the car's electronics powered.
At 35 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The DB357 belongs to the Deta DETA Power range. [More Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Inside the DB357: lead-acid technology

The DB357 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the DB357 needs no special registration: just connect it.

## What to look at before buying the DB357

- If your car has Start-Stop, the DB357 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 240 A or less, the DB357 covers your engine.
- Your current battery should say about 35 Ah; a little more is also fine.
- The DB357 needs 187 × 127 × 220 mm of space: measure it with the hold-down clamp in place.

## Frequently asked questions about the Deta DB357

### DB357 or DA406: which one suits me?

Compared with the DB357, the Deta DA406 has 5 Ah more and 110 A more cranking power. If your current battery says 350 A or more, choose the DA406; if it says 240 A or less, the DB357 is enough. Both measure 187 × 127 × 220 mm, so they fit the same tray.

### Can the Deta DB357 be used in a car with Start-Stop?

No. The DB357 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Deta DB357 weigh?

8.9 kg, with 35 Ah of capacity. For reference, the Deta DA406 (40 Ah) weighs 9.3 kg.

### Which battery is equivalent to the Deta DB357?

### Which charger does the Deta DB357 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.
