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 10,5 Ah C20 🔋 Cold cranking 175 A EN-1 📏 Dimensions 150×88×105 mm ⚙️ Technology AGM 🧭 Polarity Positive on the left ## Description ## Motorcycle battery Fulbat FT12A-BS 10.5Ah 175A 12V 12*V* Voltage 10.5*Ah* Capacity 175*A* Cold cranking The **Fulbat FT12A-BS** is a motorcycle battery with **10.5 Ah** and **175 A** of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. Its 150 × 88 × 105 mm and the positive terminal on the left make it the exact replacement for the 10.5 Ah battery fitted as standard to many motorcycles. - Compact and lightweight format. - Holds its charge through winter storage. - Sealed and ready to fit, no acid handling. - AGM: faster recharging and better cycle resistance than a conventional battery. ### Will it fit your current battery tray? In terms of format, the Fulbat FT12A-BS measures 150 × 88 × 105 mm (length × width × height). 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. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### What the Fulbat FT12A-BS is for With 10.5 Ah, the Fulbat FT12A-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. ### Technology inside the Fulbat FT12A-BS Fulbat builds the FT12A-BS to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### What Fulbat does differently 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Warranty and coverage The Fulbat FT12A-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. ### How to make it last longer Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. 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 Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 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 **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the FT12A-BS model AGM? What does this technology offer? Yes. The FT12A-BS from Fulbat uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for motorcycles with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How is the Fulbat FT12A-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 our blog. 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 — with positive on the left 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 many years does this battery last? Expected lifespan of the Fulbat FT12A-BS is 5 to 8 years in mild-climate motorcycle use with Start-Stop. 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 measurements of the FT12A-BS model? Dimensions (length × width × height) are 150×88×105 mm — also written as 150x88x105 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. ### What polarity does the Fulbat FT12A-BS battery have? Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ### Is the FT12A-BS 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 FT12A-BS typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulbat FT12A-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. ## Equivalent batteries - [VARTA 511902023](https://baterias.com/gb/battery-varta-motorcycle-12v-11ah-ytz14s-4-511902023) - [VARTA 511901014](https://baterias.com/gb/battery-varta-moto-12v-11ah-yt12a-4-yt12a-bs-511901014) - [EXIDE AGM12-11](https://baterias.com/gb/battery-exide-agm12-11-12v-11ah-205a) - [EXIDE ETZ14-BS](https://baterias.com/gb/battery-exide-etz14-bs-12v-11ah-205a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-24*
