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 🏍️ JIS code 6N4B-2A 🔌 Voltage 6 V ⚡ Capacity 4 Ah C20 🔋 Cold cranking 35 A EN-1 📏 Dimensions 100×50×95 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the left ⚖️ Weight 0,9 kg 🏷️ Model EXIDE MOTO CONVENTIONAL 6V #️⃣ Mfr. reference 6N4B-2A ## Description ## Motorcycle battery Exide 6N4B-2A Moto Convencional 4Ah 35A 6V 6*V* Voltage 4*Ah* Capacity 35*A* Cold cranking 0.90*kg* Weight With **4 Ah** at **6 V** and **35 A** of cold cranking current (EN), the **Exide 6N4B-2A** with conventional lead-acid technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Measuring 100 × 50 × 95 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 4 Ah battery of this format. - Good balance of capacity, cranking power and price. - Sealed and ready to fit, no acid handling. - Holds its charge through winter storage. - Compact and lightweight format. ### What the Exide 6N4B-2A is for Designed for motorcycles, scooters, quads and personal watercraft, the Exide 6N4B-2A replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 0.90 kg, M00 (Hole) terminals and B0 hold-down. ### The Exide 6N4B-2A: Moto Convencional range and conventional lead-acid technology The 6N4B-2A is part of the Exide **Moto Convencional** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop. ### Dimensions, polarity and mounting It has external dimensions of 100 × 50 × 95 mm and weighs 0.90 kg. 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. It uses a B0 hold-down and M00 (Hole) terminals, the system that anchors and connects it in the vehicle. 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. ### Why choose Exide batteries Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### 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. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Official warranty The Exide 6N4B-2A 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 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 ### How is the Exide 6N4B-2A 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. ### What is the service life of the 6N4B-2A model? Expected lifespan of the Exide 6N4B-2A is 4 to 6 years in regular motorcycle use without 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 6N4B-2A model? Dimensions (length × width × height) are 100×50×95 mm — also written as 100x50x95 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. ### Which side is the positive terminal on this battery? 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 6N4B-2A 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 6N4B-2A typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide 6N4B-2A? 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 · 2026-10-27*
