Motorcycle battery Exide AGM12-9 12N9-4B-1 Moto AGM 9Ah 120A 12V
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 1 to 2 working days, the islands and the rest of the EU in 1 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 YTX9C-BS model AGM? What does this technology offer?
Yes: the YTX9C-BS from Exide uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance.
How should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.9 A for its 9 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.
How long does the Exide YTX9C-BS battery last?
As a guide, you can expect the Exide YTX9C-BS to last 4 to 6 years, keeping it charged when the bike is not in use, although the real figure may be higher or lower. 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.
What are the dimensions of the Exide YTX9C-BS battery?
Before buying, measure the space in your motorcycle: one extra millimetre can stop the hold-down clamp from closing. The Exide YTX9C-BS takes up 135×75×140 mm (length, width and height, terminals included).
What polarity does the Exide YTX9C-BS battery have?
On the Exide YTX9C-BS, the polarity is positive on the left. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring.
Will the Exide YTX9C-BS battery fit my motorcycle?
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.
Which batteries are equivalent to the Exide YTX9C-BS?
The "Equivalents" section further down lists the recommended alternatives. A battery interchangeable with the Exide YTX9C-BS must match it on dimensions (135×75×140 mm), polarity (positive on the left), capacity (9 Ah) and cranking current (120 A).
Exide AGM12-9 or Exide ETX9C-BS: which one to choose?
Same range and the same performance as the AGM12-9. Compared with the AGM12-9 it has the same Ah and cranking power. It costs 17,20 € less. Either one works; decide by price.
