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 6 V ⚡ Capacity 4,2 Ah C20 🔋 Cold cranking 25 A EN-1 📏 Dimensions 71×71×96 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ## Description ## Motorcycle battery Fulbat 6N4-2A-4 4.2Ah 25A 6V 6*V* Voltage 4.2*Ah* Capacity 25*A* Cold cranking The **Fulbat 6N4-2A-4 motorcycle battery** is rated at **6 V**, **4.2 Ah** and **25 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 71 × 71 × 96 mm format: same 4.2 Ah capacity and the positive terminal on the right. - Conventional lead-acid: the most proven and economical technology. - 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 6N4-2A-4 is for With 4.2 Ah, the Fulbat 6N4-2A-4 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. ### Size, terminals and hold-down of the Fulbat 6N4-2A-4 It has external dimensions of 71 × 71 × 96 mm. 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. 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. ### Why choose Fulbat batteries French brand Fulbat is a European reference in motorcycle, garden and leisure batteries: compact ranges, clear JIS codes and a consistent quality that workshops know well. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Technology inside the Fulbat 6N4-2A-4 Within the Fulbat catalogue, the 6N4-2A-4 is the 4.2 Ah model designed for this application. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### Usage and maintenance tips 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. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. ### Official warranty The Fulbat 6N4-2A-4 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 [[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 is the Fulbat 6N4-2A-4 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 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. ### How many years does this battery last? Expected lifespan of the Fulbat 6N4-2A-4 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 6N4-2A-4 battery? Dimensions (length × width × height) are 71×71×96 mm — also written as 71x71x96 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. ### Is the 6N4-2A-4 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 6N4-2A-4 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fulbat 6N4-2A-4? 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*
