90ACold cranking

With 11.6 Ah at 6 V and 90 A of cold cranking current (EN), the Fulbat 6N11A-1B with conventional lead-acid technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. Measuring 122 × 62 × 131 mm and the positive terminal on the right, it is the direct replacement for motorcycles fitted from the factory with a 11.6 Ah battery of this format.

  • Good balance of capacity, cranking power and price.
  • 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 Fulbat 6N11A-1B

The Fulbat 6N11A-1B is made in the 122 × 62 × 131 mm format. 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.

What the Fulbat 6N11A-1B is for

The Fulbat 6N11A-1B 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.

Technology inside the Fulbat 6N11A-1B

Fulbat builds the 6N11A-1B to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

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.

Fulbat: the maker behind the 6N11A-1B

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Manufacturer's warranty

The Fulbat 6N11A-1B 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

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. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

When you get it and how to return it

Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 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 is the Fulbat 6N11A-1B 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 — with positive on the right 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.

What is the service life of the 6N11A-1B model?

Expected lifespan of the Fulbat 6N11A-1B 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 Fulbat 6N11A-1B battery?

Dimensions (length × width × height) are 122×62×131 mm — also written as 122x62x131 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.

What polarity does the Fulbat 6N11A-1B battery have?

Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

Is the 6N11A-1B 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 6N11A-1B typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which batteries are equivalent to the Fulbat 6N11A-1B?

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.
