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 ET12A-BS 🔌 Voltage 12 V ⚡ Capacity 10 Ah C20 🔋 Cold cranking 130 A EN-1 📏 Dimensions 150×90×105 mm ⚙️ Technology AGM 🧭 Polarity Positive on the left ⚖️ Weight 3,4 kg 🏷️ Model EXIDE MOTO AGM 12V #️⃣ Mfr. reference ET12A-BS ## Description ## Motorcycle battery Exide ET12A-BS Moto AGM 10Ah 130A 12V 12*V* Voltage 10*Ah* Capacity 130*A* Cold cranking 3.40*kg* Weight With **10 Ah** at **12 V** and **130 A** of cold cranking current (EN), the **Exide ET12A-BS** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Its 150 × 90 × 105 mm and the positive terminal on the left make it the exact replacement for the 10 Ah battery fitted as standard to many motorcycles. - Sealed and ready to fit, no acid handling. - AGM: faster recharging and better cycle resistance than a conventional battery. - Compact and lightweight format. - Holds its charge through winter storage. ### What the Exide ET12A-BS is for The Exide ET12A-BS is a common replacement in motorcycles, scooters, quads and personal watercraft. If your bike spends the winter standing, a trickle charger stops it reaching spring flat. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 3.40 kg, M04 terminals and B0 hold-down. ### The Exide ET12A-BS: Moto AGM range and AGM technology Within the Exide catalogue, the **Moto AGM** series groups the references designed for this use. The ET12A-BS is the 10 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. ### Size, terminals and hold-down of the Exide ET12A-BS The Exide ET12A-BS is made in the 150 × 90 × 105 mm format 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 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. ### Exide: the maker behind the ET12A-BS 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. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty. ### Care and maintenance Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. ### Official warranty The Exide ET12A-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. ### Delivery times and returns 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 Exide ET12A-BS an AGM battery and what are the benefits of AGM? Yes. The ET12A-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 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 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 — with positive on the left 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 ET12A-BS model? Expected lifespan of the Exide ET12A-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 size is this battery? Dimensions (length × width × height) are 150×90×105 mm — also written as 150x90x105 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. ### On which side is the positive of the ET12A-BS model? Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ### Is the ET12A-BS 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 ET12A-BS typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide ET12A-BS? 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 - [VARTA 508012008](https://baterias.com/gb/battery-varta-moto-12v-8ah-ytx9-4-ytx9-bs-508012008) ## 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 · 2026-10-19*
