Vibration-resistant, keeps voltage during the winter off-season and cranks first time when you take it out for a ride. ## Why this motorcycle battery? - **Same JIS reference** as your bike's original — fits first time - **Sealed and ready to use** no acid handling, no refills - **Survives winter storage** holds charge through long off-season 🔌 Voltage 12 V ⚡ Capacity 31,6 Ah C20 🔋 Cold cranking 400 A EN-1 📏 Dimensions 165×125×175 mm ⚙️ Technology AGM 🧭 Polarity Positive on the right ## Description ## Motorcycle battery Fulbat FIX30L-BS 31.6Ah 400A 12V 12*V* Voltage 31.6*Ah* Capacity 400*A* Cold cranking The **Fulbat FIX30L-BS motorcycle battery** is rated at **12 V**, **31.6 Ah** and **400 A** of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 165 × 125 × 175 mm format: same 31.6 Ah capacity and the positive terminal on the right. - Resistant to the vibration typical of two wheels. - Energetic cranking for high-compression engines. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Same JIS code as the original battery: fits first time. ### What the Fulbat FIX30L-BS is for With 31.6 Ah, the Fulbat FIX30L-BS 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 FIX30L-BS It has external dimensions of 165 × 125 × 175 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. 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. ### Technology inside the Fulbat FIX30L-BS Fulbat builds the FIX30L-BS to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### What Fulbat does differently French brand Fulbat is a European reference in motorcycle, garden and leisure batteries: compact ranges, clear JIS codes and a consistent quality that workshops know well. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Fulbat FIX30L-BS 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. ### Usage and maintenance tips If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### 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 is the Fulbat FIX30L-BS battery installed in the vehicle? 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 FIX30L-BS battery last? Expected lifespan of the Fulbat FIX30L-BS 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 Fulbat FIX30L-BS battery? Dimensions (length × width × height) are 165×125×175 mm — also written as 165x125x175 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. ### Will the Fulbat FIX30L-BS battery fit my motorcycle? 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 FIX30L-BS typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulbat FIX30L-BS? 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 · 2026-10-10*
