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 12,6 Ah C20 🔋 Cold cranking 155 A EN-1 📏 Dimensions 134×80×160 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the left ## Description ## Motorcycle battery Fulbat FB12A-B 12.6Ah 155A 12V 12*V* Voltage 12.6*Ah* Capacity 155*A* Cold cranking The **Fulbat FB12A-B** is a motorcycle battery with **12.6 Ah** and **155 A** of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It measures 134 × 80 × 160 mm and the positive terminal on the left, the format sought by anyone replacing a 12.6 Ah battery in motorcycles. - Same JIS code as the original battery: fits first time. - Conventional lead-acid: the most proven and economical technology. - Energetic cranking for high-compression engines. - Resistant to the vibration typical of two wheels. ### What the Fulbat FB12A-B is for With 12.6 Ah, the Fulbat FB12A-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. ### Dimensions, polarity and mounting The Fulbat FB12A-B is made in the 134 × 80 × 160 mm format. The positive terminal on the left 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 FB12A-B The FB12A-B is one of the Fulbat references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue. 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. ### Fulbat: the maker behind the FB12A-B 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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty. ### Manufacturer's warranty The Fulbat FB12A-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. ### Care and maintenance On batteries with filler caps, check the electrolyte level and top up only with distilled water. Avoid repeated cranking attempts on a cold bike for long: if it does not start on the third try, let the battery rest for a minute. ### Shipping, delivery and returns 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 do I fit the FB12A-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. ### What is the service life of the FB12A-B model? Expected lifespan of the Fulbat FB12A-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 are the dimensions of the Fulbat FB12A-B battery? Dimensions (length × width × height) are 134×80×160 mm — also written as 134x80x160 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 FB12A-B 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 FB12A-B typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulbat FB12A-B? 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 · 2026-10-01*
