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.
Where it fits: the Exide AGM12-31 is one of our motorcycle batteries, belongs to our Exide batteries and by capacity it sits among our 30Ah batteries.
Mostly to Harley-Davidson Road King, Harley-Davidson Street Glide, Hyosung 450 and Harley-Davidson Ultra Classic (5 orders with the vehicle identified). Treat this as guidance, not confirmation: size and positive-terminal side depend on the exact version.

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, it is AGM. In an AGM battery such as the AGM12-31, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance.
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 3 A for its 30 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.
No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.
There is no exact figure: for a battery such as the Exide AGM12-31 (AGM), a reasonable guide is 4 to 6 years, keeping it charged when the bike is not in use. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance.
Before buying, measure the space in your motorcycle: one extra millimetre can stop the hold-down clamp from closing. The Exide AGM12-31 takes up 165×130×175 mm (length, width and height, terminals included).
It has the positive on the right (polarity). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.
The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The motorcycle manufacturer's specifications always take priority over our tables.
The "Equivalents" section of this page gathers the recommended options with equivalent performance. A battery interchangeable with the Exide AGM12-31 must match it on dimensions (165×130×175 mm), polarity (positive on the right), capacity (30 Ah) and cranking current (430 A).
The Varta alternative that fits where the AGM12-31 goes, with the same polarity. Compared with the AGM12-31 it has 20 A of cold cranking more. It costs 57,65 € more. A straight swap with nothing to adapt; the difference is the price and the brand you prefer.
