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 6 V ⚡ Capacity 11,6 Ah C20 🔋 Cold cranking 90 A EN-1 📏 Dimensions 121×58×130 mm ⚙️ Technology GEL 🧭 Polarity Positive on the left ## Description ## Motorcycle battery Fulbat 6N11A-4A 11.6Ah 90A 6V 6*V* Voltage 11.6*Ah* Capacity 90*A* Cold cranking The **Fulbat 6N11A-4A motorcycle battery** is rated at **6 V**, **11.6 Ah** and **90 A** of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 121 × 58 × 130 mm format: same 11.6 Ah capacity and the positive terminal on the left. - Resistant to the vibration typical of two wheels. - Energetic cranking for high-compression engines. - GEL technology: gelled electrolyte, fully sealed and maintenance-free. - Same JIS code as the original battery: fits first time. ### Size, terminals and hold-down of the Fulbat 6N11A-4A In terms of format, the Fulbat 6N11A-4A measures 121 × 58 × 130 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Fulbat 6N11A-4A is for With 11.6 Ah, the Fulbat 6N11A-4A 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 6N11A-4A Fulbat builds the 6N11A-4A to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM. ### 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. ### Manufacturer's warranty The Fulbat 6N11A-4A 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 GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. ### When you get it and how to return it 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 Fulbat 6N11A-4A 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 6 V motorcycle charger delivering at most 10 % of its capacity: 1.2 A for its 11.6 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. ### How long does the Fulbat 6N11A-4A GEL battery last? Expected lifespan of the Fulbat 6N11A-4A 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 measurements of the 6N11A-4A GEL model? Dimensions (length × width × height) are 121×58×130 mm — also written as 121x58x130 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 6N11A-4A GEL 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. ### Will the Fulbat 6N11A-4A 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 6N11A-4A GEL typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulbat 6N11A-4A GEL? 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 · 2026-11-01*
