The Fulbat FT12B-4 GEL in practice

FT12B-4 GEL vs Fulbat FT14B-4 GEL

The Fulbat FT12B-4 GEL offers 10 Ah and 210 A cold cranking in a 150 × 69 × 130 mm case. The Fulbat FT14B-4 GEL, same brand and technology, goes up to 12 Ah and 210 A and costs €10.37 more. If the tray takes the size, extra capacity and cranking give winter margin; if not, this one is the fit.

The Fulbat FT12B-4 motorcycle battery is rated at 12 V, 10.5 Ah and 210 A of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. Its 150 × 69 × 130 mm and the positive terminal on the left make it the exact replacement for the 10.5 Ah battery fitted as standard to many motorcycles.

  • Compact and lightweight format.
  • Holds its charge through winter storage.
  • Sealed and ready to fit, no acid handling.
  • GEL: excellent resistance to deep discharge and long cycle life.

Size, terminals and hold-down of the Fulbat FT12B-4

The Fulbat FT12B-4 is made in the 150 × 69 × 130 mm format. The positive terminal on the left 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 FT12B-4 is for

The Fulbat FT12B-4 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 FT12B-4

Within the Fulbat catalogue, the FT12B-4 is the 10.5 Ah model designed for this application.

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

Fulbat has manufactured in France since 1978 and specialises in motorcycles and light vehicles. Its catalogue is short and clear, covers almost the whole fleet and works only with sealed, leak-free batteries. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Warranty and coverage

The Fulbat FT12B-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.

Care and maintenance

GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. 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.

Shipping, delivery and returns

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

Is the Fulbat FT12B-4 GEL a GEL battery? What is GEL used for?

Yes: in the FT12B-4 GEL the electrolyte is gelled. It is a sealed lead-acid GEL battery. With very good deep-discharge tolerance, it is ideal for cyclic use: solar, motorhomes, electric wheelchairs and 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: 1.1 A for its 10.5 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?

No: being GEL, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.

How many years does this battery last?

Estimated lifespan of the Fulbat FT12B-4 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 measurements of the FT12B-4 GEL model?

The Fulbat FT12B-4 GEL takes up 150×69×130 mm (length, width and height, terminals included). Before buying, measure the space in your motorcycle: one extra millimetre can stop the hold-down clamp from closing.

Which side is the positive terminal on this battery?

The FT12B-4 GEL has the positive on the left: 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.

Is the FT12B-4 GEL valid for my vehicle?

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.

What are the equivalents of the FT12B-4 GEL model?

The "Equivalents" section further down lists the recommended alternatives. To replace the Fulbat FT12B-4 GEL without modifications, the other battery must be identical in size, polarity, Ah and CCA.
