Car battery Long 48D26L Starting Series 50Ah 12V
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 × 173 × 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 × 173 × 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 6:00 pm 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 14 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 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.
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 × width × height) are 260×173×225 mm — also written as 260x173x225 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.
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 — 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 — 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.
