## Description

## Motorcycle battery Exide 12N9-3B Moto Convencional 9Ah 85A 12V

12*V* Voltage
9*Ah* Capacity
85*A* Cold cranking
3.10*kg* Weight

The **Exide 12N9-3B** from the **Moto Convencional** range is a motorcycle battery with **9 Ah** and **85 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 135 × 75 × 140 mm format: same 9 Ah capacity and the positive terminal on the right.
- Resistant to the vibration typical of two wheels.
- Energetic cranking for high-compression engines.
- Conventional lead-acid: the most proven and economical technology.
- Same JIS code as the original battery: fits first time.

### What the Exide 12N9-3B is for

With 9 Ah, the Exide 12N9-3B 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 12N9-3B: Moto Convencional range and conventional lead-acid technology

The 12N9-3B is part of the Exide **Moto Convencional** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

### Dimensions, polarity and mounting

The Exide 12N9-3B is made in the 135 × 75 × 140 mm format and weighs 3.10 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. It uses a B0 hold-down and M06 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### Exide: the maker behind the 12N9-3B

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.

### Care and maintenance

If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.

### Warranty and coverage

The Exide 12N9-3B 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.

### Shipping, delivery and returns

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] 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

### How do I fit the 12N9-3B model in my motorcycle?

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 this page. 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 — 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.

### How long does the Exide 12N9-3B battery last?

Expected lifespan of the Exide 12N9-3B is 4 to 6 years in regular motorcycle use without 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.

### What are the dimensions of the Exide 12N9-3B battery?

Dimensions (length × width × height) are 135×75×140 mm — also written as 135x75x140 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.

### Will the Exide 12N9-3B 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 12N9-3B typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Exide 12N9-3B?

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.
