- Sealed and ready to fit, no acid handling.
- GEL: excellent resistance to deep discharge and long cycle life.
- Compact and lightweight format.
- Holds its charge through winter storage.
Dimensions, polarity and mounting
It has external dimensions of 120 × 60 × 130 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
What the Fulbat FB5L-B is for
Designed for motorcycles, scooters, quads and personal watercraft, the Fulbat FB5L-B replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering.
Technology inside the Fulbat FB5L-B
Fulbat builds the FB5L-B to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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.
What Fulbat does differently
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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.
Manufacturer's warranty
The Fulbat FB5L-B 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. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.
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 1 to 2 working days, the islands and the rest of the EU in 1 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
Is the FB5L-B GEL model a gel battery? Where is it used?
Yes, this model is a GEL battery: sealed lead-acid with the electrolyte in gel form. Deep discharges are its strong point, so it suits cyclic use: solar, motorhomes, electric wheelchairs or motorcycles. Charge it only with a GEL-specific smart charger; its voltage limit is below that of an AGM.
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 5.3 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?
No: being GEL, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.
What is the service life of the FB5L-B GEL model?
Estimated lifespan of the Fulbat FB5L-B GEL: 4 to 6 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 dimensions of the Fulbat FB5L-B GEL battery?
Its dimensions are 120×60×130 mm, also written 120x60x130 mm; the height already includes the terminals. Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing.
What polarity does the Fulbat FB5L-B GEL battery have?
The FB5L-B GEL has the positive on the right: that is its polarity. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.
Will the Fulbat FB5L-B GEL 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 FB5L-B GEL typically fits a wide range of European vehicles thanks to its standard DIN case format. Always cross-check with what the motorcycle manufacturer states in the owner's handbook.
