Ready to use, sealed and vibration-resistant. Fits any model that takes the same JIS reference — the code your mechanic recognises at a glance. ### 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 8,4 Ah C20 🔋 Cold cranking 85 A EN-1 📏 Dimensions 135×75×133 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ## Description ## Motorcycle battery Fulbat FB7L-B2 8.4Ah 85A 12V 12*V* Voltage 8.4*Ah* Capacity 85*A* Cold cranking The **Fulbat FB7L-B2 motorcycle battery** is rated at **12 V**, **8.4 Ah** and **85 A** of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. Its 135 × 75 × 133 mm and the positive terminal on the right make it the exact replacement for the 8.4 Ah battery fitted as standard to many motorcycles. - Sealed and ready to fit, no acid handling. - Good balance of capacity, cranking power and price. - Compact and lightweight format. - Holds its charge through winter storage. ### Dimensions, polarity and mounting In terms of format, the Fulbat FB7L-B2 measures 135 × 75 × 133 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. ### What the Fulbat FB7L-B2 is for With 8.4 Ah, the Fulbat FB7L-B2 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. ### Technology inside the Fulbat FB7L-B2 Fulbat builds the FB7L-B2 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. ### Manufacturer's warranty The Fulbat FB7L-B2 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. ### Care and maintenance 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. ### Shipping, delivery and returns Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### How do I fit the FB7L-B2 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 FB7L-B2 battery last? Expected lifespan of the Fulbat FB7L-B2 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 FB7L-B2 battery? Dimensions (length × width × height) are 135×75×133 mm — also written as 135x75x133 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 FB7L-B2 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 FB7L-B2 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the FB7L-B2 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 — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-04*
