Motorcycle battery Fulbat 6N4-2A-4 4.2Ah 25A 6V
The Fulbat 6N4-2A-4 motorcycle battery is rated at 6 V, 4.2 Ah and 25 A of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 71 × 71 × 96 mm format: same 4.2 Ah capacity and the positive terminal on the right.
- Conventional lead-acid: the most proven and economical technology.
- Same JIS code as the original battery: fits first time.
- Resistant to the vibration typical of two wheels.
- Energetic cranking for high-compression engines.
What the Fulbat 6N4-2A-4 is for
With 4.2 Ah, the Fulbat 6N4-2A-4 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.
Size, terminals and hold-down of the Fulbat 6N4-2A-4
It has external dimensions of 71 × 71 × 96 mm. 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. 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.
Why choose Fulbat batteries
French brand Fulbat is a European reference in motorcycle, garden and leisure batteries: compact ranges, clear JIS codes and a consistent quality that workshops know well. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Technology inside the Fulbat 6N4-2A-4
Within the Fulbat catalogue, the 6N4-2A-4 is the 4.2 Ah model designed for this application.
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.
Usage and maintenance tips
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. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.
Official warranty
The Fulbat 6N4-2A-4 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
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.

Frequently asked questions
How is the Fulbat 6N4-2A-4 battery installed in the vehicle?
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 our blog. 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 many years does this battery last?
Expected lifespan of the Fulbat 6N4-2A-4 is 4 to 7 years in regular use (depends on technology and climate). 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 Fulbat 6N4-2A-4 battery?
Dimensions (length × width × height) are 71×71×96 mm — also written as 71x71x96 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.
Is the 6N4-2A-4 valid for my vehicle?
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 6N4-2A-4 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Fulbat 6N4-2A-4?
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.
