The Fulbat B38-6A GEL in practice

B38-6A GEL vs Fulbat B49-6 GEL

The Fulbat B38-6A GEL offers 13 Ah and 105 A cold cranking in a 119 × 83 × 161 mm case. The Fulbat B49-6 GEL, same brand and technology, stays at 10 Ah and 80 A with 28 mm less length and costs €12.53 less. Coming from the smaller reference, this is a straight upgrade: same case, more reserve, same fitting.

The Fulbat B38-6A is a motorcycle battery with 13.7 Ah and 105 A of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. It measures 119 × 83 × 161 mm and the positive terminal on the right, the format sought by anyone replacing a 13.7 Ah battery in motorcycles.

  • Energetic cranking for high-compression engines.
  • Resistant to the vibration typical of two wheels.
  • Same JIS code as the original battery: fits first time.
  • GEL technology: gelled electrolyte, fully sealed and maintenance-free.

What the Fulbat B38-6A is for

With 13.7 Ah, the Fulbat B38-6A covers the starting of motorcycles, scooters, quads and personal watercraft. The JIS code on your current battery label is the safest way to confirm equivalence.

Dimensions, polarity and mounting

It has external dimensions of 119 × 83 × 161 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. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

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. All the Fulbat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Technology inside the Fulbat B38-6A

Within the Fulbat catalogue, the B38-6A is the 13.7 Ah model designed for this application.

A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.

How to make it last longer

If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. 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.

Official warranty

The Fulbat B38-6A 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.

Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 1 to 2 working days in mainland Spain and 1 to 3 working days in mainland Portugal, 1 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions

Is the B38-6A 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. 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 6 V motorcycle charger delivering at most 10 % of its capacity: 1.4 A for its 13.7 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?

As a guide, you can expect the Fulbat B38-6A GEL to last 4 to 6 years, keeping it charged when the bike is not in use, although the real figure may be higher or lower. 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 B38-6A GEL battery?

It measures 119×83×161 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.

On which side is the positive of the B38-6A GEL model?

On the Fulbat B38-6A GEL, the polarity is positive on the right. To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.

Is the B38-6A GEL valid for my vehicle?

The B38-6A GEL typically fits a wide range of European vehicles thanks to its standard DIN case format. 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)). In every case, the motorcycle manufacturer's specifications (owner's handbook) take precedence.

Which batteries are equivalent to the Fulbat B38-6A GEL?

The "Equivalents" section of this page gathers the recommended options with equivalent performance. A direct equivalent needs what this B38-6A GEL offers: 119×83×161 mm, positive on the right, the same Ah and CCA and GEL technology.
