OEM quality at white-label prices: calcium-silver grids, low self-discharge and compatible with all modern electrical systems. ## 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 50 Ah C20 πŸ“ Dimensions 260Γ—173Γ—225 mm βš–οΈ Weight 9,55 kg 🏷️ Model Starting Series ## Description ## Car battery Long 48D26L Starting Series 50Ah 12V 12*V* Voltage 50*Ah* Capacity 9.55*kg* Weight The **Long 48D26L** from the **Starting Series** range delivers **50 Ah** at **12 V**: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It measures 260 Γ— 173 Γ— 225 mm, the format sought by anyone replacing a 50 Ah battery in cars. - Original-equipment build quality without the dealership price. - Reliable cold starts, even after weeks without driving. - Direct replacement for the original battery in size and terminals. - Designed to last several years under normal daily use. ### Dimensions, polarity and mounting It has external dimensions of 260 Γ— 173 Γ— 225 mm and weighs 9.55 kg. 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. ### What the Long 48D26L is for With 50 Ah, the Long 48D26L 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 9.55 kg. ### The Long 48D26L within the Starting Series range Within the Long catalogue, the **Starting Series** series groups the references designed for this use. The 48D26L is the 50 Ah model of that family, with the same performance as its siblings in other sizes. ### 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 48D26L 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 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. ### When you get it and how to return it Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### How do I fit the 48D26L 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 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 Long 48D26L battery last? Expected lifespan of the Long 48D26L 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 48D26L battery? Dimensions (length Γ— width Γ— height) are 260Γ—173Γ—225 mm β€” also written as 260x173x225 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. ### Is the 48D26L 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 48D26L typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the 48D26L 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. ## 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· 2026-10-08*
