Car battery Deta DC400 Standard 40Ah 320A 12V
The Deta DC400 from the Standard range delivers 40 Ah and 320 A of cold cranking current (EN) at 12 V: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It replaces the original battery without adaptation in cars with a 175 × 175 × 190 mm format: same 40 Ah capacity and the positive terminal on the right.
In short: the Deta DC400 (40 Ah, 320 A, 175 × 175 × 190 mm, positive terminal on the right). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Exide EC400 and Tudor TC400.
- Conventional lead-acid: the most proven and economical technology.
- Reliable cold starts, even after weeks without driving.
- Direct replacement for the original battery in size and terminals.
- Original-equipment build quality without the dealership price.
Dimensions, polarity and mounting
In terms of format, the Deta DC400 measures 175 × 175 × 190 mm (length × width × height) and weighs 10.40 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B13 hold-down, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
What the Deta DC400 is for
Designed for passenger cars with conventional starting, without a Start-Stop system, the Deta DC400 is the direct replacement when your vehicle uses a 40 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 10.40 kg and B13 hold-down.
The Deta DC400: Standard range and conventional lead-acid technology
The DC400 is part of the Deta Standard range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.
Why choose Deta batteries
Deta is the German brand of the Exide group: batteries built with original-equipment technology and a very complete range for cars, Start-Stop, trucks, motorcycles and leisure. We guarantee that every Deta arrives new, charged and with the manufacturer's full warranty.
Warranty and coverage
The Deta DC400 comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.
Usage and maintenance tips
Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.
Shipping, delivery and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
How do I change this battery step by step?
In most cars it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — with positive on the right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Deta DC400 battery last?
Expected lifespan of the Deta DC400 is 4 to 6 years in regular car use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the measurements of the DC400 model?
Dimensions (length × width × height) are 175×175×190 mm — also written as 175x175x190 mm — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
What polarity does the Deta DC400 battery have?
Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
Is the DC400 valid for my vehicle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DC400 typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the DC400 model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop cars. See the "Equivalents" section to view recommended options at the same performance level.
