Motorcycle battery Exide AGM12-19.1 Moto AGM 18Ah 270A 12V
The Exide AGM12-19.1 motorcycle battery is rated at 12 V, 18 Ah and 270 A of cold cranking current (EN) from the Moto AGM range, and is designed for motorcycles, scooters, quads and personal watercraft. Its 175 × 90 × 155 mm and the positive terminal on the left make it the exact replacement for the 18 Ah battery fitted as standard to many motorcycles.
- Compact and lightweight format.
- Holds its charge through winter storage.
- Sealed and ready to fit, no acid handling.
- AGM: faster recharging and better cycle resistance than a conventional battery.
Dimensions, polarity and mounting
In terms of format, the Exide AGM12-19.1 measures 175 × 90 × 155 mm (length × width × height) and weighs 6.10 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. 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 AGM12-19.1 is for
With 18 Ah, the Exide AGM12-19.1 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 6.10 kg.
The Exide AGM12-19.1: Moto AGM range and AGM technology
The AGM12-19.1 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.
Exide: the maker behind the AGM12-19.1
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Manufacturer's warranty
The Exide AGM12-19.1 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. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.
Delivery times and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
Is the AGM12-19.1 model AGM? What does this technology offer?
Yes. The AGM12-19.1 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 should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 1.8 A for its 18 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.
Does it need maintenance?
No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.
What is the service life of the AGM12-19.1 model?
Expected lifespan of the Exide AGM12-19.1 is 4 to 6 years, keeping it charged when the bike is not in use. 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 measurements of the AGM12-19.1 model?
Dimensions (length × width × height) are 175×90×155 mm — also written as 175x90x155 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.
On which side is the positive of the AGM12-19.1 model?
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 AGM12-19.1 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 AGM12-19.1 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide AGM12-19.1?
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.
