It measures 243 × 127 × 200 mm, the format sought by anyone replacing a 36 Ah battery in classic cars. - Robust construction against vibration. - Format and terminals compatible with period battery trays. - Respects the vehicle's original electrical system. - Conventional lead-acid: the most proven and economical technology. ### What the Lucas LC037 is for The Lucas LC037 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 11 kg. ### Technology inside the Lucas LC037 Lucas builds the LC037 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### Dimensions, polarity and mounting In terms of format, the Lucas LC037 measures 243 × 127 × 200 mm (length × width × height) and weighs 11 kg. 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. ### Lucas: the maker behind the LC037 Lucas is a historic British brand of automotive electrical components. Its batteries offer reliable starting and keen value for everyday cars. All the Lucas batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Care and maintenance Check the resting voltage and terminals periodically; corrosion in old wiring is the most frequent cause of weak starts. A classic car often stands for long spells: a trickle charger connected in the garage is the best investment for the battery. ### Warranty and coverage The Lucas LC037 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. ### 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 do I fit the LC037 model in my car? 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 — 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. ### What is the service life of the LC037 model? Expected lifespan of the Lucas LC037 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 LC037 model? Dimensions (length × width × height) are 243×127×200 mm — also written as 243x127x200 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. ### Will the Lucas LC037 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 LC037 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Lucas LC037? 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-19*
