Delivers the cranking amps the engine needs in cold weather and keeps stable voltage for modern car loads (ECU, sensors, climate control, infotainment). ### Why this car battery? - **Original-equipment quality** without dealership prices - **Lasts 4 to 6 years** buy once instead of twice - **Real human tech support** if you have any doubts before buying πŸ”Œ Voltage 12 V ⚑ Capacity 40 Ah C20 πŸ”‹ Cold cranking 320 A EN-1 πŸ“ Dimensions 175Γ—175Γ—190 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the right βš–οΈ Weight 10,4 kg 🏷️ Model DETA Standard ## Description ## Car battery Deta DC400 Standard 40Ah 320A 12V 12*V* Voltage 40*Ah* Capacity 320*A* Cold cranking 10.40*kg* Weight 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 Γ— 175 Γ— 190 mm format: same 40 Ah capacity and the positive terminal on the right. - 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 Γ— 175 Γ— 190 mm (length Γ— width Γ— 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 [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] 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 this page. 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 (βˆ’) 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 β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). 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 Γ— width Γ— height) are 175Γ—175Γ—190 mm β€” also written as 175x175x190 mm β€” 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. ### 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 β€” 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 β€” 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. ## Equivalent batteries - [EXIDE EC400](https://baterias.com/gb/battery-exide-ec400-12v) - [TUDOR TC400](https://baterias.com/gb/battery-tudor-tc400-12v-40ah-320a) - [VARTA B36](https://baterias.com/gb/battery-varta-b36-12v-44ah-420a) - [TUDOR TB440](https://baterias.com/gb/battery-tudor-tb440-44ah-400a) - [VARTA A16](https://baterias.com/gb/battery-varta-a16-12v-40ah-340a) - [EXIDE EB440](https://baterias.com/gb/battery-exide-eb440-12v-44ah-400a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-09-28*
