Fulbat FTX14AH-BS / FB14-A2/B2 GEL 12V 14,7Ah 210A is a motorcycle starter battery with standard JIS code (the one on your bike's original label). Ready to use, sealed and vibration-resistant. Fits any model that takes the same JIS reference — the code your mechanic recognises at a glance.

The Fulbat FTX14AH-BS / FB14-A2/B2 motorcycle battery is rated at 12 V, 14.7 Ah and 210 A of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. Measuring 135 × 90 × 167 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 14.7 Ah battery of this format.
With 14.7 Ah, the Fulbat FTX14AH-BS / FB14-A2/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.
Within the Fulbat catalogue, the FTX14AH-BS / FB14-A2/B2 is the 14.7 Ah model designed for this application.
In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.
The Fulbat FTX14AH-BS / FB14-A2/B2 is made in the 135 × 90 × 167 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. 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.
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.
Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.
The Fulbat FTX14AH-BS / FB14-A2/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.
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 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.

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 — 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.
Expected lifespan of the Fulbat FTX14AH-BS / FB14-A2/B2 GEL 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.
Dimensions (length × width × height) are 135×90×167 mm — also written as 135x90x167 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.
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 FTX14AH-BS / FB14-A2/B2 GEL typically fits a wide range of European vehicles thanks to its standard DIN case format.
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.
