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 55 Ah C20 πŸ“ Dimensions 232Γ—173Γ—225 mm βš–οΈ Weight 12,5 kg 🏷️ Model Starting Series ## Description ## Car battery Long 55D23L Starting Series 55Ah 12V 12*V* Voltage 55*Ah* Capacity 12.50*kg* Weight The **Long 55D23L** from the **Starting Series** range delivers **55 Ah** at **12 V**: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It measures 232 Γ— 173 Γ— 225 mm, the format sought by anyone replacing a 55 Ah battery in cars. - Direct replacement for the original battery in size and terminals. - Original-equipment build quality without the dealership price. - Reliable cold starts, even after weeks without driving. - Low self-discharge: copes with long stops without losing charge. ### What the Long 55D23L is for The Long 55D23L 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 12.50 kg. ### Will it fit your current battery tray? It has external dimensions of 232 Γ— 173 Γ— 225 mm and weighs 12.50 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. ### The Long 55D23L within the Starting Series range The **Starting Series** is the Long range the 55D23L 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. ### Long: the maker behind the 55D23L 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. ### Manufacturer's warranty The Long 55D23L 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 55D23L 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 55D23L battery last? Expected lifespan of the Long 55D23L 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 measurements of the 55D23L model? Dimensions (length Γ— width Γ— height) are 232Γ—173Γ—225 mm β€” also written as 232x173x225 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. ### Does this 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 55D23L typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Long 55D23L? 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· 2026-10-01*
