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 12N5.5-3B 🔌 Voltage 12 V ⚡ Capacity 6 Ah C20 🔋 Cold cranking 45 A EN-1 📏 Dimensions 135×60×130 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ⚖️ Weight 2,1 kg 🏷️ Model EXIDE MOTO CONVENTIONAL 12V #️⃣ Mfr. reference 12N5,5-3B ## Description ## Motorcycle battery Exide 12N5 5-3B Moto Convencional 6Ah 45A 12V 12*V* Voltage 6*Ah* Capacity 45*A* Cold cranking 2.10*kg* Weight The **Exide 12N5 5-3B** from the **Moto Convencional** range is a motorcycle battery with **6 Ah** and **45 A** of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. Measuring 135 × 60 × 130 mm and the positive terminal on the right, it is the direct replacement for motorcycles fitted from the factory with a 6 Ah battery of this format. - Holds its charge through winter storage. - Compact and lightweight format. - Good balance of capacity, cranking power and price. - Sealed and ready to fit, no acid handling. ### What the Exide 12N5 5-3B is for The Exide 12N5 5-3B 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. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.10 kg. ### The Exide 12N5 5-3B: Moto Convencional range and conventional lead-acid technology The 12N5 5-3B 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. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Will it fit your current battery tray? The Exide 12N5 5-3B is made in the 135 × 60 × 130 mm format and weighs 2.10 kg. 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. ### Why choose Exide batteries With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty. ### Care and maintenance 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 Exide 12N5 5-3B 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. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How do I change this battery step by step? 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 long does the Exide 12N5,5-3B battery last? Expected lifespan of the Exide 12N5,5-3B 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 12N5,5-3B model? Dimensions (length × width × height) are 135×60×130 mm — also written as 135x60x130 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 12N5,5-3B 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 12N5,5-3B typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide 12N5,5-3B? 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. ## Equivalent batteries - [VARTA 506011004](https://baterias.com/gb/battery-varta-moto-12v-5-5ah-12n5_5-3b-506011004) ## Reviews - **Average rating**: 4.81 / 5 (23 reviews) ## 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 · 2026-09-29*
