Measuring 165 × 130 × 176 mm and the positive terminal on the right, it is the direct replacement for motorcycles fitted from the factory with a 31.6 Ah battery of this format. - Good balance of capacity, cranking power and price. - Sealed and ready to fit, no acid handling. - Holds its charge through winter storage. - Compact and lightweight format. ### What the Fulbat FB30L-B is for With 31.6 Ah, the Fulbat FB30L-B covers the starting of motorcycles, scooters, quads and personal watercraft. The JIS code on your current battery label is the safest way to confirm equivalence. ### Size, terminals and hold-down of the Fulbat FB30L-B It has external dimensions of 165 × 130 × 176 mm. 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. ### Technology inside the Fulbat FB30L-B Fulbat builds the FB30L-B 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. ### Why choose Fulbat batteries Fulbat has manufactured in France since 1978 and specialises in motorcycles and light vehicles. Its catalogue is short and clear, covers almost the whole fleet and works only with sealed, leak-free batteries. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Fulbat FB30L-B comes with the **manufacturer's official warranty**. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger. ### How to make it last longer On batteries with filler caps, check the electrolyte level and top up only with distilled water. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How do I fit the FB30L-B model in my motorcycle? In most motorcycles 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 motorcycles with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Fulbat FB30L-B battery last? Expected lifespan of the Fulbat FB30L-B 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 165×130×176 mm — also written as 165x130x176 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Is the FB30L-B 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 FB30L-B typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the FB30L-B 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 motorcycles. 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 — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-09*
