Motorcycle battery Fulbat FB10L-A2/B2 11.6Ah 120A 12V
The Fulbat FB10L-A2/B2 motorcycle battery is rated at 12 V, 11.6 Ah and 120 A of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. Measuring 133 × 90 × 145 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.
- Holds its charge through winter storage.
- Compact and lightweight format.
- GEL: excellent resistance to deep discharge and long cycle life.
- Sealed and ready to fit, no acid handling.
What the Fulbat FB10L-A2/B2 is for
Designed for motorcycles, scooters, quads and personal watercraft, the Fulbat FB10L-A2/B2 replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering.
Will it fit your current battery tray?
In terms of format, the Fulbat FB10L-A2/B2 measures 133 × 90 × 145 mm (length × width × height). 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. 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.
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Technology inside the Fulbat FB10L-A2/B2
The FB10L-A2/B2 is one of the Fulbat references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.
GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.
Usage and maintenance tips
If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.
Manufacturer's warranty
The Fulbat FB10L-A2/B2 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.
When you get it and how to return it
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 do I fit the FB10L-A2/B2 GEL 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 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 FB10L-A2/B2 GEL 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 measurements of the FB10L-A2/B2 GEL model?
Dimensions (length × width × height) are 133×90×145 mm — also written as 133x90x145 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 FB10L-A2/B2 GEL 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 FB10L-A2/B2 GEL typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Fulbat FB10L-A2/B2 GEL?
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.
