Size, terminals and hold-down of the Exide 12N5-3B
The Exide 12N5-3B is made in the 120 × 60 × 130 mm format and weighs 2 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
What the Exide 12N5-3B is for
With 5 Ah, the Exide 12N5-3B 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 2 kg, M06 terminals and B0 hold-down.
The Exide 12N5-3B: Moto Convencional range and conventional lead-acid technology
The Moto Convencional is the Exide range the 12N5-3B belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.
What Exide does differently
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. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty.
Official warranty
The Exide 12N5-3B 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.
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.
Delivery times 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: 0.5 A for its 5 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.
What is the service life of the 12N5-3B model?
Estimated lifespan of the Exide 12N5-3B: 3 to 5 years, keeping it charged when the bike is not in use. Treat it as an approximate guide, as every case is different. 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 measurements of the 12N5-3B model?
Before buying, measure the space in your motorcycle: one extra millimetre can stop the hold-down clamp from closing. The Exide 12N5-3B takes up 120×60×130 mm (length, width and height, terminals included).
Which side is the positive terminal on this battery?
The 12N5-3B has the positive on the right: that is its polarity. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit.
Will the Exide 12N5-3B 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 interchangeable batteries are there for this one?
The "Equivalents" section further down lists the recommended alternatives. To replace the Exide 12N5-3B without modifications, the other battery must be identical in size, polarity, Ah and CCA.

Same family as the 12N5-3B, one step up in performance. Compared with the 12N5-3B it has 25 A of cold cranking more. It costs 0,90 € less. Worth it on big-displacement bikes, with lots of electrical equipment or that sleep in the cold; on an average bike the 12N5-3B does the job.
Exide 12N5-3B or Varta 12N5-3B.YB5L-B: which one to choose?
The Varta alternative that fits where the 12N5-3B goes, with the same polarity. Compared with the 12N5-3B it has 20 A of cold cranking more. It costs 27,20 € more. A straight swap with nothing to adapt; the difference is the price and the brand you prefer.
