The Exide AGM12-9 motorcycle battery is rated at 12 V, 9 Ah and 120 A of cold cranking current (EN) from the Moto AGM range, and is designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 135 × 75 × 140 mm format: same 9 Ah capacity and the positive terminal on the left.

  • 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.

Will it fit your current battery tray?

The Exide AGM12-9 is made in the 135 × 75 × 140 mm format 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.

What the Exide AGM12-9 is for

The Exide AGM12-9 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 3.20 kg, M04 terminals and B0 hold-down.

The Exide AGM12-9: Moto AGM range and AGM technology

The AGM12-9 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.

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.

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. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty.

Official warranty

The Exide AGM12-9 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.

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.

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.

Frequently asked questions

Is the AGM12-9 model AGM? What does this technology offer?

Yes. The AGM12-9 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 AGM12-9 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 AGM12-9 battery last?

Expected lifespan of the Exide AGM12-9 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 AGM12-9 battery?

Dimensions (length × width × height) are 135×75×140 mm — also written as 135x75x140 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 AGM12-9 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.

Will the Exide AGM12-9 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 AGM12-9 typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which batteries are equivalent to the Exide AGM12-9?

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.
