Its 302 Γ— 171 Γ— 225 mm make it the exact replacement for the 75 Ah battery fitted as standard to many cars. - Stable voltage for the vehicle electronics (ECU, sensors, climate control). - Low self-discharge: copes with long stops without losing charge. - Direct replacement for the original battery in size and terminals. - Original-equipment build quality without the dealership price. ### What the Long 65D31L is for Designed for passenger cars with conventional starting, without a Start-Stop system, the Long 65D31L is the direct replacement when your vehicle uses a 75 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 12.50 kg. ### Size, terminals and hold-down of the Long 65D31L In terms of format, the Long 65D31L measures 302 Γ— 171 Γ— 225 mm (length Γ— width Γ— height) and weighs 12.50 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Long 65D31L within the Starting Series range The **Starting Series** is the Long range the 65D31L belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. ### What Long does differently Long batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty. ### Official warranty The Long 65D31L 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. ### Care and maintenance Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges. 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. ### When you get it and how to return it 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 Long 65D31L 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. ### What is the service life of the 65D31L model? Expected lifespan of the Long 65D31L is 4 to 7 years in regular use (depends on technology and climate). 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 Long 65D31L battery? Dimensions (length Γ— width Γ— height) are 302Γ—171Γ—225 mm β€” also written as 302x171x225 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 Long 65D31L 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 65D31L typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Long 65D31L? 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. ## 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*
