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 🔌 Voltage 12 V ⚡ Capacity 54 Ah C20 🔋 Cold cranking 500 A EN-1 📏 Dimensions 242×175×175 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ⚖️ Weight 12,9 kg 🏷️ Model EXIDE CLASSIC ## Description ## Classic car battery Exide EC542 Classic 54Ah 500A 12V 12*V* Voltage 54*Ah* Capacity 500*A* Cold cranking 12.90*kg* Weight With **54 Ah** at **12 V** and **500 A** of cold cranking current (EN), the **Exide EC542** from the **Classic** range covers the starting demand of classic and vintage cars with their original electrical system. It replaces the original battery without adaptation in classic cars with a 242 × 175 × 175 mm format: same 54 Ah capacity and the positive terminal on the right. - Format and terminals compatible with period battery trays. - Robust construction against vibration. - Conventional lead-acid: the most proven and economical technology. - Respects the vehicle's original electrical system. ### What the Exide EC542 is for The Exide EC542 is designed for classic and vintage cars with their original electrical system: a format compatible with period trays and a stable voltage for original ignition and wiring. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 12.90 kg. ### The Exide EC542: Classic range and conventional lead-acid technology Within the Exide catalogue, the **Classic** series groups the references designed for this use. The EC542 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. ### Dimensions, polarity and mounting The Exide EC542 is made in the 242 × 175 × 175 mm format 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Why choose Exide batteries Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Care and maintenance A classic car often stands for long spells: a trickle charger connected in the garage is the best investment for the battery. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Official warranty The Exide EC542 comes with the **manufacturer's official warranty** against manufacturing defects. The warranty does not cover deep discharge through inactivity: in a classic, a trickle charger is the best protection. ### Shipping, delivery and returns 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 Exide EC542 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 (−) 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 — 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 Exide EC542 battery last? Expected lifespan of the Exide EC542 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 Exide EC542 battery? Dimensions (length × width × height) are 242×175×175 mm — also written as 242x175x175 mm and correspond to the European LB2 case size — 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 Exide EC542 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 — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The EC542 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide EC542? 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. ## Equivalent batteries - [TUDOR TC542](https://baterias.com/gb/battery-tudor-tc542-12v-54ah-500a) - [VARTA C11](https://baterias.com/gb/battery-varta-c11-12v-53ah-500a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-13*
