As a rough estimate, the Fulbat U1-9 Ca/Ca typically lasts 4 to 6 years in normal lorry use; it is a guide figure, not a guaranteed period. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of truck and whether it has Start-Stop. ### What are the measurements of the U1-9 Ca/Ca model? Before buying, measure the space in your truck: one extra millimetre can stop the hold-down clamp from closing. The Fulbat U1-9 Ca/Ca takes up 195×130×180 mm (length, width and height, terminals included). ### What polarity does the Fulbat U1-9 Ca/Ca battery have? Polarity of the Fulbat U1-9 Ca/Ca: positive on the left. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. ### Will the Fulbat U1-9 Ca/Ca battery fit my truck? For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The truck manufacturer's specifications always take priority over our tables. The U1-9 Ca/Ca typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the U1-9 Ca/Ca model? Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the U1-9 Ca/Ca, 28 Ah (300 A cranking). The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop trucks an EFB should not be replaced with a conventional battery. ### Fulbat U1-9 Ca/Ca or Exide U1R-11: which one to choose? Same case and same technology as the U1-9 Ca/Ca: an alternative by size, not an official equivalent. Compared with the U1-9 Ca/Ca it has 2 Ah more. It costs €93.50 more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ## 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 · 2026-11-13*
