## Description

Deta car and truck batteries, including EFB and AGM Start-Stop models such as the DL800; buy online with the shipping cost shown upfront.
Passenger car models (flooded, EFB and AGM) are also listed in [Deta car batteries](https://bateriasonline.es/en/deta-car-batteries). Here you also get the truck and auxiliary batteries.

Here are the DETA 12 V batteries, laid out for side-by-side comparison: cars with or without Start-Stop, auxiliary batteries, trucks, tractors and construction machinery. Each listing shows capacity in Ah, cold cranking amps (CCA, EN), size in mm, polarity and technology.
Filter on those figures and keep only the models that fit your vehicle.

## How to choose your DETA battery

Start from the battery currently fitted: its label gives the technology, Ah, CCA and dimensions. The DETA replacement should match that technology or step up, never down. A car that left the factory with AGM needs AGM; one with EFB takes either EFB or AGM.
- **Size and hold-down**: length, width and height in mm, plus the type of base ledge that the clamp grips.
- **Polarity**: check which side the positive terminal sits on; short cables leave no room for mistakes.
- **Ah and CCA**: match or exceed the original figures. Extra CCA helps in winter and with diesel engines.

## Which DETA range suits your driving

For a car without Start-Stop, DETA Standard handles everyday needs, DETA Power adds reserve for better-equipped models and DETA Senator3 targets lots of short trips or cold climates. You can compare all three under [car batteries](https://bateriasonline.es/en/car-batteries). If your engine cuts out at traffic lights, head to [Start-Stop batteries](https://bateriasonline.es/en/start-stop-batteries-agm-efb). Fleets, tractors and site machinery will find the PRO ranges under [truck batteries](https://bateriasonline.es/en/truck-agricultural-batteries). To learn more about the brand and its technologies, visit the [DETA brand page](https://bateriasonline.es/en/deta-batteries).

## DETA FAQs

### Can I fit a DETA EFB where an AGM was installed?

No. If the vehicle came with AGM, the replacement must be AGM too. Going the other way, from EFB to AGM, is fine.

### Does the new battery need registering in the car?

On many vehicles with Start-Stop and electronic battery management, yes: the system has to know the battery is new and what type it is in order to charge it correctly. Check your vehicle handbook.
