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 ETZ10-BS 🔌 Voltage 12 V ⚡ Capacity 9 Ah C20 🔋 Cold cranking 145 A EN-1 📏 Dimensions 150×90×95 mm ⚙️ Technology AGM 🧭 Polarity Positive on the left ⚖️ Weight 3,4 kg 🏷️ Model EXIDE MOTO AGM 12V #️⃣ Mfr. reference ETZ10-BS ## Description ## Motorcycle battery Exide ETZ10-BS Moto AGM 9Ah 145A 12V 12*V* Voltage 9*Ah* Capacity 145*A* Cold cranking 3.40*kg* Weight With **9 Ah** at **12 V** and **145 A** of cold cranking current (EN), the **Exide ETZ10-BS** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Its 150 × 90 × 95 mm and the positive terminal on the left make it the exact replacement for the 9 Ah battery fitted as standard to many motorcycles. - Compact and lightweight format. - Holds its charge through winter storage. - Sealed and ready to fit, no acid handling. - AGM: faster recharging and better cycle resistance than a conventional battery. ### What the Exide ETZ10-BS is for With 9 Ah, the Exide ETZ10-BS 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 3.40 kg, M12 terminals and B0 hold-down. ### Dimensions, polarity and mounting In terms of format, the Exide ETZ10-BS measures 150 × 90 × 95 mm (length × width × height) and weighs 3.40 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 M12 terminals, the system that anchors and connects it in the vehicle. 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 Exide ETZ10-BS: Moto AGM range and AGM technology Within the Exide catalogue, the **Moto AGM** series groups the references designed for this use. The ETZ10-BS is the 9 Ah model of that family, with the same performance as its siblings in other sizes. 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 Exide does differently 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Official warranty The Exide ETZ10-BS 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. ### 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### 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 ### Is the ETZ10-BS model AGM? What does this technology offer? Yes. The ETZ10-BS from Exide uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for motorcycles with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How do I fit the ETZ10-BS model in my motorcycle? 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 ETZ10-BS battery last? Expected lifespan of the Exide ETZ10-BS is 5 to 8 years in mild-climate motorcycle use with 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 ETZ10-BS model? Dimensions (length × width × height) are 150×90×95 mm — also written as 150x90x95 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 ETZ10-BS 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 ETZ10-BS typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the ETZ10-BS 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 AGM12-8](https://baterias.com/gb/battery-exide-agm12-8-12v-86ah-145a) - [VARTA 506015005](https://baterias.com/gb/battery-varta-moto-12v-6ah-ytx7a-4-ytx7a-bs-506015005) - [VARTA 508909015](https://baterias.com/gb/battery-varta-motorcycle-12v-9ah-ytz10s-fa-508909015) ## Reviews - **Average rating**: 4.76 / 5 (29 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 · 2026-10-07*
