Motorcycle battery Exide ETX12-BS Moto AGM 10Ah 150A 12V
The Exide ETX12-BS motorcycle battery is rated at 12 V, 10 Ah and 150 A of cold cranking current (EN) from the Moto AGM range, and is designed for motorcycles, scooters, quads and personal watercraft. Measuring 150 × 90 × 130 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 10 Ah battery of this format.
In short: the Exide ETX12-BS (10 Ah, 150 A, 150 × 90 × 130 mm, positive terminal on the left). Verified equivalent alternatives: Exide AGM12-10 and Varta YTX12-4.
- Holds its charge through winter storage.
- Compact and lightweight format.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Sealed and ready to fit, no acid handling.
What the Exide ETX12-BS is for
With 10 Ah, the Exide ETX12-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 3.90 kg, M04 terminals and B0 hold-down.
Size, terminals and hold-down of the Exide ETX12-BS
In terms of format, the Exide ETX12-BS measures 150 × 90 × 130 mm (length × width × height) and weighs 3.90 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. 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 ETX12-BS: Moto AGM range and AGM technology
Within the Exide catalogue, the Moto AGM series groups the references designed for this use. The ETX12-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.
What Exide does differently
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.
Manufacturer's warranty
The Exide ETX12-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.
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. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.
Delivery times and returns
Order before 6:00 pm 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 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Bueno, pues no puedo opinar nada concretamente de esta batería ya que me enviaron una Varta si previo aviso de cambio. Les envíe un correo y todavía estoy esperando respuesta dos semanas después. La batería ya está colocada y solo espero que sea de la misma calidad que la que pedí. Por cierto, venía ya con el ácido dentro.

Frequently asked questions
Is the ETX12-BS model AGM? What does this technology offer?
Yes. The ETX12-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 is the Exide ETX12-BS 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 — 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 ETX12-BS model?
Expected lifespan of the Exide ETX12-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 dimensions of the Exide ETX12-BS battery?
Dimensions (length × width × height) are 150×90×130 mm — also written as 150x90x130 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.
Which side is the positive terminal on this battery?
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 ETX12-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 ETX12-BS typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide ETX12-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.
