Vibration-resistant, keeps voltage during the winter off-season and cranks first time when you take it out for a ride. ### 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 YT14BBS, YT14B4 🔌 Voltage 12 V ⚡ Capacity 13 Ah C20 🔋 Cold cranking 175 A EN-1 📏 Dimensions 150×70×145 mm ⚙️ Technology AGM Quadflex ⚖️ Weight 4,1 kg 🏷️ Model MOTOBATT QUADFLEX #️⃣ Mfr. reference MBT14B4 ## Description ## Motorcycle battery Motobatt YT14BBS-YT14B4 Quadflex 13Ah 175A 12V JIS code YT14BBS-YT14B4 12*V* Voltage 13*Ah* Capacity 175*A* Cold cranking 4.10*kg* Weight With **13 Ah** at **12 V** and **175 A** of cold cranking current (EN), the **Motobatt YT14BBS-YT14B4** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 150 × 70 × 145 mm format: same 13 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 YT14BBS-YT14B4 is for With 13 Ah, the Motobatt YT14BBS-YT14B4 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 4.10 kg. ### The Motobatt YT14BBS-YT14B4: Quadflex range and AGM technology The YT14BBS-YT14B4 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. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Dimensions, polarity and mounting The Motobatt YT14BBS-YT14B4 is made in the 150 × 70 × 145 mm format and weighs 4.10 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Why choose Motobatt batteries Motobatt batteries stand out for capacity and cranking current above the original battery in the same tray, thanks to a compact AGM design and the four-terminal Quadflex system. We guarantee that every Motobatt arrives new, charged and with the manufacturer's full warranty. ### Care and maintenance If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Official warranty The Motobatt YT14BBS-YT14B4 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 is the Motobatt YT14BBS-YT14B4 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. ### What is the service life of the YT14BBS-YT14B4 model? Expected lifespan of the Motobatt YT14BBS-YT14B4 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 measurements of the YT14BBS-YT14B4 model? Dimensions (length × width × height) are 150×70×145 mm — also written as 150x70x145 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 YT14BBS-YT14B4 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 YT14BBS-YT14B4 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Motobatt YT14BBS-YT14B4? 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. ## Reviews - **Average rating**: 4.85 / 5 (10 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 · 2026-09-30*
