Motorcycle battery Exide AGM12-4 Moto AGM 3Ah 50A 12V
The Exide AGM12-4 from the Moto AGM range is a motorcycle battery with 3 Ah and 50 A of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It measures 115 × 70 × 85 mm and the positive terminal on the right, the format sought by anyone replacing a 3 Ah battery in motorcycles.
In short: the Exide AGM12-4 (3 Ah, 50 A, 115 × 70 × 85 mm, positive terminal on the right). Verified equivalent alternatives: Exide ETX4L-BS and Varta YTX4L-4.
- Energetic cranking for high-compression engines.
- Resistant to the vibration typical of two wheels.
- Same JIS code as the original battery: fits first time.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
Dimensions, polarity and mounting
The Exide AGM12-4 is made in the 115 × 70 × 85 mm format and weighs 1.20 kg. The positive terminal on the right 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.
What the Exide AGM12-4 is for
Designed for motorcycles, scooters, quads and personal watercraft, the Exide AGM12-4 replaces the original battery of bikes that use this code or format. 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 1.20 kg, M04 terminals and B0 hold-down.
The Exide AGM12-4: Moto AGM range and AGM technology
Within the Exide catalogue, the Moto AGM series groups the references designed for this use. The AGM12-4 is the 3 Ah model of that family, with the same performance as its siblings in other sizes.
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.
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. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Manufacturer's warranty
The Exide AGM12-4 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.
Usage and maintenance tips
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.
Delivery times 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 this battery AGM? What is it for?
Yes. The AGM12-4 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 AGM12-4 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 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 right 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 AGM12-4 model?
Expected lifespan of the Exide AGM12-4 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 AGM12-4 battery?
Dimensions (length × width × height) are 115×70×85 mm — also written as 115x70x85 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 right. 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.
Does this 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 AGM12-4 typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the AGM12-4 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.
