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 35 Ah C10 🔋 Cold cranking 420 A EN-1 📏 Dimensions 195×130×156 mm ⚙️ Technology AGM Quadflex ⚖️ Weight 10,5 kg 🏷️ Model MOTOBATT QUADFLEX #️⃣ Mfr. reference MBU1R-35 ## Description ## Motorcycle battery Motobatt MBU1R-35 Quadflex 35Ah 420A 12V 12*V* Voltage 35*Ah* Capacity 420*A* Cold cranking 10.50*kg* Weight The **Motobatt MBU1R-35 motorcycle battery** is rated at **12 V**, **35 Ah** and **420 A** of cold cranking current (EN) from the **Quadflex** range, and is designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 195 × 130 × 156 mm format: same 35 Ah capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - 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 Motobatt MBU1R-35 is for With 35 Ah, the Motobatt MBU1R-35 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 10.50 kg. ### Dimensions, polarity and mounting In terms of format, the Motobatt MBU1R-35 measures 195 × 130 × 156 mm (length × width × height) and weighs 10.50 kg. 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. ### The Motobatt MBU1R-35: Quadflex range and AGM technology The MBU1R-35 is part of the Motobatt **Quadflex** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### What Motobatt does differently Motobatt is the motorcycle battery specialist with Quadflex technology: four terminals that let you connect the battery in any position and a sealed AGM construction ready to fit. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Motobatt MBU1R-35 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. ### Usage and maintenance tips Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. 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. ### When you get it and how to return it Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### How is the Motobatt MBU1R-35 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 — 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 Motobatt MBU1R-35 battery last? Expected lifespan of the Motobatt MBU1R-35 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 Motobatt MBU1R-35 battery? Dimensions (length × width × height) are 195×130×156 mm — also written as 195x130x156 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 Motobatt MBU1R-35 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 MBU1R-35 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the MBU1R-35 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. ## 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 · 2026-10-23*
