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 6,8 Ah C20 🔋 Cold cranking 85 A EN-1 📏 Dimensions 139×66×102 mm ⚙️ Technology GEL 🧭 Polarity Positive on the right ## Description ## Motorcycle battery Fulbat FTX6,5L-BS 6.8Ah 85A 12V 12*V* Voltage 6.8*Ah* Capacity 85*A* Cold cranking The **Fulbat FTX6,5L-BS** is a motorcycle battery with **6.8 Ah** and **85 A** of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 139 × 66 × 102 mm format: same 6.8 Ah capacity and the positive terminal on the right. - GEL technology: gelled electrolyte, fully sealed and maintenance-free. - Same JIS code as the original battery: fits first time. - Resistant to the vibration typical of two wheels. - Energetic cranking for high-compression engines. ### What the Fulbat FTX6,5L-BS is for The Fulbat FTX6,5L-BS is a common replacement in motorcycles, scooters, quads and personal watercraft. If your bike spends the winter standing, a trickle charger stops it reaching spring flat. ### Will it fit your current battery tray? In terms of format, the Fulbat FTX6,5L-BS measures 139 × 66 × 102 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. 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 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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty. ### Technology inside the Fulbat FTX6,5L-BS Within the Fulbat catalogue, the FTX6,5L-BS is the 6.8 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. ### How to make it last longer Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. ### Official warranty The Fulbat FTX6,5L-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. ### Shipping, delivery and returns Order **before 6:00 pm** 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 **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is the Fulbat FTX6,5L-BS GEL a GEL battery? What is GEL used for? Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years. ### How should this motorcycle battery be charged? With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.7 A for its 6.8 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### Does it need maintenance? No: being GEL, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time. ### What is the service life of the FTX6,5L-BS GEL model? Expected lifespan of the Fulbat FTX6,5L-BS GEL is 4 to 6 years, keeping it charged when the bike is not in use. 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 FTX6,5L-BS GEL battery? Dimensions (length × width × height) are 139×66×102 mm — also written as 139x66x102 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 FTX6,5L-BS GEL battery have? Polarity: positive on the right. 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. ### Will the Fulbat FTX6,5L-BS GEL 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 FTX6,5L-BS GEL typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? 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 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-30*
