It replaces the original battery without adaptation in ride-on mowers with a 195 × 130 × 180 mm format: same 28 Ah capacity and the positive terminal on the right. - Compact format for small trays. - Good tolerance to self-discharge. - Conventional lead-acid: the most proven and economical technology. - Reliable starting after months of winter storage. ### What the Fulbat U1R-9 Ca/Ca is for With 28 Ah, the Fulbat U1R-9 Ca/Ca starts ride-on mowers, tillers and garden machinery and copes with garden-engine vibration. ### Technology inside the Fulbat U1R-9 Ca/Ca Fulbat builds the U1R-9 Ca/Ca to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Will it fit your current battery tray? In terms of format, the Fulbat U1R-9 Ca/Ca measures 195 × 130 × 180 mm (length × width × height). The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Why choose Fulbat batteries Fulbat has manufactured in France since 1978 and specialises in motorcycles and light vehicles.

In most trucks 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 (−) 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 trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Fulbat U1R-9 Ca/Ca battery last? Expected lifespan of the Fulbat U1R-9 Ca/Ca 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 size is this battery? Dimensions (length × width × height) are 195×130×180 mm — also written as 195x130x180 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Is the U1R-9 Ca/Ca 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 U1R-9 Ca/Ca typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulbat U1R-9 Ca/Ca? 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 trucks. 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 — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-30*
