In terms of format, the Fulbat FB30CL-B measures 165 × 130 × 192 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
Technology inside the Fulbat FB30CL-B
Within the Fulbat catalogue, the FB30CL-B is the 31.6 Ah model designed for this application.
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 FB30CL-B
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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.
Manufacturer's warranty
The Fulbat FB30CL-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
On batteries with filler caps, check the electrolyte level and top up only with distilled water. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.
Delivery times and returns

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.

Frequently asked questions
How should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 3.2 A for its 31.6 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?
Yes: it is a conventional lead-acid battery. Check the electrolyte level from time to time and, if it drops, top up with distilled water to the mark.
What is the service life of the FB30CL-B model?
As a rough estimate, the Fulbat FB30CL-B typically lasts 3 to 5 years, keeping it charged when the bike is not in use; it is a guide figure, not a guaranteed period. 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 FB30CL-B model?
Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing. Its dimensions are 165×130×192 mm, also written 165x130x192 mm; the height already includes the terminals.
On which side is the positive of the FB30CL-B model?
Polarity of the Fulbat FB30CL-B: positive on the right. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Seen from the front, terminals towards you, the positive (+) is the post with the red ring.
Does this 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)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook.
What are the equivalents of the FB30CL-B model?
The "Equivalents" section of this page gathers the recommended options with equivalent performance. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the FB30CL-B, 31.6 Ah (300 A cranking).
