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 54 Ah C20 πŸ”‹ Cold cranking 500 A EN-1 πŸ“ Dimensions 242Γ—175Γ—175 mm βš™οΈ Technology Lead-acid 🧭 Polarity Positive on the right βš–οΈ Weight 12,9 kg 🏷️ Model DETA Standard ## Description ## Car battery Deta DC542 Standard 54Ah 500A 12V 12*V* Voltage 54*Ah* Capacity 500*A* Cold cranking 12.90*kg* Weight The **Deta DC542** from the **Standard** range delivers **54 Ah** and **500 A** of cold cranking current (EN) at **12 V**: the usual specification for passenger cars with conventional starting, without a Start-Stop system. Its 242 Γ— 175 Γ— 175 mm and the positive terminal on the right make it the exact replacement for the 54 Ah battery fitted as standard to many cars. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). - Good balance of capacity, cranking power and price. - Designed to last several years under normal daily use. - Low self-discharge: copes with long stops without losing charge. ### What the Deta DC542 is for The Deta DC542 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 12.90 kg, 1 terminals and B13 hold-down. ### Dimensions, polarity and mounting In terms of format, the Deta DC542 measures 242 Γ— 175 Γ— 175 mm (length Γ— width Γ— height) and weighs 12.90 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 and 1 terminals, 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. ### The Deta DC542: Standard range and conventional lead-acid technology Within the Deta catalogue, the **Standard** series groups the references designed for this use. The DC542 is the 54 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### What Deta does differently Deta combines German engineering with Exide's industrial capacity. Its Power, Senator and PowerPRO series cover everything from urban cars to construction machinery. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Manufacturer's warranty The Deta DC542 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 In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. 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. ### Delivery times 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 is the Deta DC542 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 DC542 battery last? Expected lifespan of the Deta DC542 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 DC542 model? Dimensions (length Γ— width Γ— height) are 242Γ—175Γ—175 mm β€” also written as 242x175x175 mm and correspond to the European LB2 case size 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 DC542 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 DC542 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the DC542 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 EC542](https://baterias.com/gb/battery-exide-ec542-12v-54ah-500a) - [TUDOR TC542](https://baterias.com/gb/battery-tudor-tc542-12v-54ah-500a) - [VARTA D59](https://baterias.com/gb/battery-varta-d59-12v-60ah-540a) - [VARTA D21](https://baterias.com/gb/battery-varta-d21-12v-61ah-600a) - [TUDOR TB602](https://baterias.com/gb/battery-tudor-tb602-60ah-540a) - [TUDOR TA612](https://baterias.com/gb/battery-tudor-ta612-61ah-600a) - [EXIDE EA612](https://baterias.com/gb/battery-exide-ea612-12v-61ah-600a) ## 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· 2026-09-30*
