Delivers reliable cold-cranks even after weeks of inactivity and supports stable auxiliary loads (lights, 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 90 Ah C20 πŸ”‹ Cold cranking 680 A EN-1 πŸ“ Dimensions 306Γ—173Γ—222 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the left βš–οΈ Weight 19,9 kg 🏷️ Model DETA Standard ## Description ## Car battery Deta DC905 Standard 90Ah 680A 12V 12*V* Voltage 90*Ah* Capacity 680*A* Cold cranking 19.90*kg* Weight The **Deta DC905 car battery** is rated at **12 V**, **90 Ah** and **680 A** of cold cranking current (EN) from the **Standard** range, and is designed for passenger cars with conventional starting, without a Start-Stop system. Measuring 306 Γ— 173 Γ— 222 mm and the positive terminal on the left, it is the direct replacement for cars fitted from the factory with a 90 Ah battery of this format. - Low self-discharge: copes with long stops without losing charge. - Designed to last several years under normal daily use. - Good balance of capacity, cranking power and price. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). ### What the Deta DC905 is for With 90 Ah, the Deta DC905 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 19.90 kg and Korean B1 hold-down. ### Will it fit your current battery tray? It has external dimensions of 306 Γ— 173 Γ— 222 mm and weighs 19.90 kg. The positive terminal on the left 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 Korean B1 hold-down, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### The Deta DC905: Standard range and conventional lead-acid technology The DC905 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. ### Manufacturer's warranty The Deta DC905 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. ### How to make it last longer 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. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How is the Deta DC905 battery installed in the vehicle? 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 DC905 battery last? Expected lifespan of the Deta DC905 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 dimensions of the Deta DC905 battery? Dimensions (length Γ— width Γ— height) are 306Γ—173Γ—222 mm β€” also written as 306x173x222 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. ### Will the Deta DC905 battery fit my car? 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 DC905 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Deta DC905? 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 EC905](https://baterias.com/gb/battery-exide-ec905-12v-90ah-680a) - [TUDOR TC905](https://baterias.com/gb/battery-tudor-tc905-12v-90ah-680a) - [TUDOR TB955](https://baterias.com/gb/battery-tudor-tb955-95ah-720a) - [TUDOR TA955](https://baterias.com/gb/battery-tudor-ta955-95ah-800a) - [EXIDE EA955](https://baterias.com/gb/battery-exide-ea955-12v-95ah-800a) - [TUDOR TL955](https://baterias.com/gb/battery-tudor-tl955-12v-95ah-800a) ## 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· 2026-10-01*
