The Fulbat FTZ12S GEL in practice
FTZ12S GEL vs Fulbat FB14A-A2 GEL
The Fulbat FTZ12S GEL offers 11 Ah and 210 A cold cranking in a 150 × 88 × 110 mm case. The Fulbat FB14A-A2 GEL, same brand and technology, goes up to 14 Ah and 200 A with 16 mm less length and costs €25.55 more. If the tray takes the size, extra capacity and cranking give winter margin; if not, this one is the fit.

Motorcycle battery Fulbat FTZ12S 11.6Ah 210A 12V
The Fulbat FTZ12S is a motorcycle battery with 11.6 Ah and 210 A of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 150 × 88 × 110 mm format: same 11.6 Ah capacity and the positive terminal on the left.
- GEL technology: gelled electrolyte, fully sealed and maintenance-free.
- Same JIS code as the original battery: fits first time.
- Resistant to the vibration typical of two wheels.
- Energetic cranking for high-compression engines.
Will it fit your current battery tray?
It has external dimensions of 150 × 88 × 110 mm. 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 FTZ12S is for
The Fulbat FTZ12S 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 FTZ12S
Fulbat builds the FTZ12S to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.
Fulbat: the maker behind the FTZ12S
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Official warranty
The Fulbat FTZ12S 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.
Usage and maintenance tips
GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.
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
Is the FTZ12S GEL model a gel battery? Where is it used?
Yes, GEL technology (11.6 Ah): a sealed lead-acid battery whose electrolyte is in gel form. Take care when charging: it requires a smart charger with a GEL mode, because it accepts a lower charge voltage than an AGM. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles).
How should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 1.2 A for its 11.6 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 long does the Fulbat FTZ12S GEL battery last?
There is no exact figure: for a battery such as the Fulbat FTZ12S GEL (GEL), a reasonable guide is 4 to 6 years, keeping it charged when the bike is not in use. What weighs most: temperature (cold makes starts harder and intense heat evaporates the electrolyte), frequent short trips, the condition of the alternator and charging system, power draw while parked and maintenance.
What are the dimensions of the Fulbat FTZ12S GEL battery?
Its dimensions are 150×88×110 mm, also written 150x88x110 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.
On which side is the positive of the FTZ12S GEL model?
It has the positive on the left (polarity). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.
Will the Fulbat FTZ12S GEL battery fit my motorcycle?
Three routes: the "Compatible vehicles" tab on this page, with the vehicles verified by our technical team; your number plate in the finder, from which DGT/DVLA/KBA detect model and engine; and WhatsApp, with make, model, engine and year, during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook.
What are the equivalents of the FTZ12S GEL model?
See the "Equivalents" section of this page for the recommended options at the same performance level. To replace the Fulbat FTZ12S GEL without modifications, the other battery must be identical in size, polarity, Ah and CCA.
Fulbat FTZ12S GEL or Fulbat FTZ14S GEL: which one to choose?
Same case and same technology as the FTZ12S GEL: an alternative by size, not an official equivalent. Compared with the FTZ12S GEL it has 20 A of cold cranking more. It costs 5,81 € more. If the polarity matches and your bike had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
