Motorcycle battery Exide AGM12-8 Moto AGM 8.6Ah 145A 12V
With 8.6 Ah at 12 V and 145 A of cold cranking current (EN), the Exide AGM12-8 with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 150 × 87 × 95 mm format: same 8.6 Ah capacity and the positive terminal on the left.
In short: the Exide AGM12-8 (8 Ah, 145 A, 150 × 90 × 95 mm, positive terminal on the left). Verified equivalent alternatives: Exide ETZ10-BS and Varta YTX7A-BS.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Same JIS code as the original battery: fits first time.
- Resistant to the vibration typical of two wheels.
- Energetic cranking for high-compression engines.
What the Exide AGM12-8 is for
The Exide AGM12-8 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, M12 terminals and B0 hold-down.
Size, terminals and hold-down of the Exide AGM12-8
It has external dimensions of 150 × 87 × 95 mm 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. 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.
The Exide AGM12-8: Moto AGM range and AGM technology
The AGM12-8 is part of the Exide Moto AGM range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.
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.
Warranty and coverage
The Exide AGM12-8 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
Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.
Shipping, delivery 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.

Frequently asked questions
Is the AGM12-8 model AGM? What does this technology offer?
Yes. The AGM12-8 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 AGM12-8 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.
How long does the Exide AGM12-8 battery last?
Expected lifespan of the Exide AGM12-8 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 150×90×95 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.
What polarity does the Exide AGM12-8 battery have?
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 AGM12-8 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 AGM12-8 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide AGM12-8?
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.
