Fulbat FTX9-BS Motorcycle MF · Battery 8.4Ah 135A AGM

Motorcycle battery Fulbat FTX9-BS 8.4Ah 135A 12V

The Fulbat FTX9-BS motorcycle battery is rated at 12 V, 8.4 Ah and 135 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 150 × 87 × 105 mm format: same 8.4 Ah capacity and the positive terminal on the left.

In short: the Fulbat FTX9-BS (8 Ah, 135 A, 150 × 87 × 105 mm, positive left). Verified equivalent alternatives: Varta TTZ14S-BS and Varta YT12A-BS.

• Resistant to the vibration typical of two wheels.
• Energetic cranking for high-compression engines.
• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Same JIS code as the original battery: fits first time.

What the Fulbat FTX9-BS is for

Designed for motorcycles, scooters, quads and personal watercraft, the Fulbat FTX9-BS replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering.

Technology inside the Fulbat FTX9-BS

The FTX9-BS is one of the Fulbat references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Will it fit your current battery tray?

In terms of format, the Fulbat FTX9-BS measures 150 × 87 × 105 mm (length × width × height). 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.

Fulbat: the maker behind the FTX9-BS

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. We guarantee that every Fulbat arrives new, charged and with the manufacturer's full warranty.

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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

Warranty and coverage

The Fulbat FTX9-BS 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.
