## Description

## The Deta DC412 at a glance

The Deta DC412 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 DC412 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 41 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The DC412 belongs to the Deta DETA Standard range. [The full range of Deta batteries](https://bateriasonline.es/en/deta-batteries)

## Check this before ordering the Deta DC412

- The DC412 needs 207 × 175 × 175 mm of space (European case size LB1): measure it with the hold-down clamp in place.
- With the terminals facing you, the positive terminal of the DC412 is on the right.
- Your current battery should say about 41 Ah; a little more is also fine.
- The DC412 delivers 370 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the DC412 is not the right one: it needs an EFB or an AGM.
