Exide AGM12-31 12V 30Ah 430A is a sealed motorcycle battery ready to fit, with the JIS reference your mechanic recognises at a glance. Vibration-resistant, keeps voltage during the winter off-season and cranks first time when you take it out for a ride.

The Exide AGM12-31 from the Moto AGM range is a motorcycle battery with 30 Ah and 430 A of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 165 × 130 × 175 mm format: same 30 Ah capacity and the positive terminal on the right.
With 30 Ah, the Exide AGM12-31 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 9.80 kg.
In terms of format, the Exide AGM12-31 measures 165 × 130 × 175 mm (length × width × height) and weighs 9.80 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
The AGM12-31 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.
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.
The Exide AGM12-31 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.
Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. 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.
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.

Yes. The AGM12-31 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.
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.
Expected lifespan of the Exide AGM12-31 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.
Dimensions (length × width × height) are 165×130×175 mm — also written as 165x130x175 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.
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.
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 AGM12-31 typically fits a wide range of European vehicles thanks to its standard DIN case format.
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.
