Measuring 135 × 75 × 140 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 9 Ah battery of this format.
In short: the Exide 12N9-4B-1 (9 Ah, 85 A, 135 × 75 × 140 mm, positive terminal on the left). Verified equivalent alternatives: Exide EB9-B and Varta 12N9-4B-1.

- Sealed and ready to fit, no acid handling.
- Holds its charge through winter storage.
- Compact and lightweight format.
Size, terminals and hold-down of the Exide 12N9-4B-1
It has external dimensions of 135 × 75 × 140 mm and weighs 3.10 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. It uses a B0 hold-down and M06 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 12N9-4B-1 is for
With 9 Ah, the Exide 12N9-4B-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 3.10 kg, M06 terminals and B0 hold-down.
The Exide 12N9-4B-1: Moto Convencional range and conventional lead-acid technology
Within the Exide catalogue, the Moto Convencional series groups the references designed for this use. The 12N9-4B-1 is the 9 Ah model of that family, with the same performance as its siblings in other sizes.
The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.
Exide: the maker behind the 12N9-4B-1
With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Warranty and coverage
The Exide 12N9-4B-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
If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. On batteries with filler caps, check the electrolyte level and top up only with distilled water.
Shipping, delivery and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions
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?
Yes: it is a conventional lead-acid battery. Check the electrolyte level from time to time and, if it drops, top up with distilled water to the mark.
How long does the Exide 12N9-4B-1 battery last?
As a guide, you can expect the Exide 12N9-4B-1 to last 3 to 5 years, keeping it charged when the bike is not in use, although the real figure may be higher or lower. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance.
What are the dimensions of the Exide 12N9-4B-1 battery?
Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing. Its dimensions are 135×75×140 mm, also written 135x75x140 mm; the height already includes the terminals.
On which side is the positive of the 12N9-4B-1 model?
On the Exide 12N9-4B-1, 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 12N9-4B-1 battery fit my motorcycle?
For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook. The 12N9-4B-1 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide 12N9-4B-1?
To replace the Exide 12N9-4B-1 without modifications, the other battery must be identical in size, polarity, Ah and CCA. The "Equivalents" section of this page gathers the recommended options with equivalent performance.
Exide 12N9-4B-1 or Exide ETX9C-BS: which one to choose?
It is the sealed AGM of the same size: maintenance-free, it withstands vibration and winter lay-ups better than the 12N9-4B-1. Compared with the 12N9-4B-1 it has 35 A of cold cranking more. It costs 13,70 € less. Essential if your bike came with AGM; if it had a conventional battery, it is a durability and leak-safety upgrade, not an obligation.
Exide 12N9-4B-1 or Exide EB9-B: which one to choose?
The next step up from the 12N9-4B-1 in the same range and the same case. Compared with the 12N9-4B-1 it has 15 A of cold cranking more. It costs 1,00 € more. Worth it on big-displacement bikes, with lots of electrical equipment or that sleep in the cold; on an average bike the 12N9-4B-1 does the job.
