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 7 Ah C20 🔋 Cold cranking 75 A EN-1 📏 Dimensions 135×75×135 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ⚖️ Weight 2,9 kg 🏷️ Model EXIDE Conventional #️⃣ Mfr. reference 12N7-3B ## Description ## Motorcycle battery Exide 12N7-3B Conventional 7Ah 75A 12V 12*V* Voltage 7*Ah* Capacity 75*A* Cold cranking 2.90*kg* Weight The **Exide 12N7-3B** from the **Conventional** range is a motorcycle battery with **7 Ah** and **75 A** of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. Its 135 × 75 × 135 mm and the positive terminal on the right make it the exact replacement for the 7 Ah battery fitted as standard to many motorcycles. - Sealed and ready to fit, no acid handling. - Good balance of capacity, cranking power and price. - Compact and lightweight format. - Holds its charge through winter storage. ### What the Exide 12N7-3B is for With 7 Ah, the Exide 12N7-3B 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. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.90 kg, M06 terminals and B0 hold-down. ### The Exide 12N7-3B: Conventional range and conventional lead-acid technology The 12N7-3B is part of the Exide **Conventional** 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 135 × 75 × 135 mm and weighs 2.90 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. It uses a B0 hold-down and M06 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Exide: the maker behind the 12N7-3B 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. ### Care and maintenance On batteries with filler caps, check the electrolyte level and top up only with distilled water. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. ### Manufacturer's warranty The Exide 12N7-3B 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. ### When you get it and how to return it 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 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. ### What is the service life of the 12N7-3B model? Expected lifespan of the Exide 12N7-3B 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 Exide 12N7-3B battery? Dimensions (length × width × height) are 135×75×135 mm — also written as 135x75x135 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. ### Will the Exide 12N7-3B 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 12N7-3B typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the 12N7-3B model? 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 - [EXIDE EB7L-B](https://baterias.com/gb/battery-exide-eb7l-b-12v-8ah-85a) - [EXIDE 12N9-3B](https://baterias.com/gb/battery-exide-12n9-3b-12v-9ah-85a) - [FULBAT FB7L-B/B2 GEL](https://baterias.com/gb/battery-fulbat-fb7l-b-b2-gel-12v-8-4ah-100a) ## 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 · 2026-09-30*
