Motorcycle battery Fulbat 6N4-2A-4 4.2Ah 25A 6V

6VVoltage
4.2AhCapacity
25ACold cranking

The Fulbat 6N4-2A-4 motorcycle battery is rated at 6 V, 4.2 Ah and 25 A of cold cranking current (EN), and is designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery without adaptation in motorcycles with a 71 × 71 × 96 mm format: same 4.2 Ah capacity and the positive terminal on the right.

  • Conventional lead-acid: the most proven and economical technology.
  • Same JIS code as the original battery: fits first time.
  • Resistant to the vibration typical of two wheels.
  • Energetic cranking for high-compression engines.

What the Fulbat 6N4-2A-4 is for

With 4.2 Ah, the Fulbat 6N4-2A-4 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.

Size, terminals and hold-down of the Fulbat 6N4-2A-4

It has external dimensions of 71 × 71 × 96 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 6N4-2A-4

Within the Fulbat catalogue, the 6N4-2A-4 is the 4.2 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.

Usage and maintenance tips

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. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.

Official warranty

The Fulbat 6N4-2A-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.

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

How should this motorcycle battery be charged?

With a 6 V motorcycle charger delivering at most 10 % of its capacity: 0.5 A for its 4.2 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.

How many years does this battery last?

As a guide, you can expect the Fulbat 6N4-2A-4 to last 3 to 5 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 6N4-2A-4 battery?

Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing. Its dimensions are 71×71×96 mm, also written 71x71x96 mm; the height already includes the terminals.

What polarity does the Fulbat 6N4-2A-4 battery have?

On the Fulbat 6N4-2A-4, 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. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit.

Is the 6N4-2A-4 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)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook.

Which batteries are equivalent to the Fulbat 6N4-2A-4?

The "Equivalents" section of this page gathers the recommended options with equivalent performance. To replace the Fulbat 6N4-2A-4 without modifications, the other battery must be identical in size, polarity, Ah and CCA.
