Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 3.20 kg, M04 terminals and B0 hold-down. ### Will it fit your current battery tray? In terms of format, the Exide ETX9C-BS measures 135 × 75 × 139 mm (length × width × height) and weighs 3.20 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 M04 terminals, the system that anchors and connects it in the vehicle. 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 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. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### The Exide ETX9C-BS: Moto AGM range and AGM technology Within the Exide catalogue, the **Moto AGM** series groups the references designed for this use. The ETX9C-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. ### How to make it last longer 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. ### Manufacturer's warranty The Exide ETX9C-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. ### Shipping, delivery and returns Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 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 **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the YTX9C-BS model AGM? What does this technology offer? Yes. The Exide YTX9C-BS is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. It withstands more cycles than a conventional battery and copes better with heat. ### How should this motorcycle battery be charged? With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.9 A for its 9 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### Does it need maintenance? No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time. ### What is the service life of the YTX9C-BS model? Estimated lifespan of the Exide YTX9C-BS: 4 to 6 years, keeping it charged when the bike is not in use. Treat it as an approximate guide, as every case is different. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance. Cold demands more at every start and intense heat evaporates the electrolyte. ### What are the dimensions of the Exide YTX9C-BS battery? Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 135×75×140 mm in length × width × height, with the terminals included in the height. ### On which side is the positive of the YTX9C-BS model? The YTX9C-BS has the positive on the left: that is its polarity. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on. ### Will the Exide YTX9C-BS battery fit my motorcycle? Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your motorcycle is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the motorcycle manufacturer's specifications (owner's handbook) take precedence. ### What are the equivalents of the YTX9C-BS model? A direct equivalent needs what this YTX9C-BS offers: 135×75×140 mm, positive on the left, the same Ah and CCA and AGM technology. The options at the same level are in the "Equivalents" section of this page. ### Exide ETX9C-BS or Exide AGM12-9: which one to choose? Sister reference of the ETX9C-BS, practically identical on paper. Compared with the ETX9C-BS it has the same Ah and cranking power. It costs 17,20 € more. Choose by price and availability: in real use you will not notice a difference. ## Equivalent batteries - [EXIDE AGM12-9](https://baterias.com/gb/battery-exide-agm12-9-12v-9ah-120a) ## 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 · 2026-11-09*
