Fulbat FDM12-900 · Marine battery 12V 180Ah 900A AGM CARBON

Marine battery Fulbat FDM12-900 180Ah 900A 12V

With 180 Ah at 12 V and 900 A of cold cranking current (EN), the Fulbat FDM12-900 is built for motor and sailing boats, both for engine starting and onboard services. Measuring 512 × 222 × 218 mm and the positive terminal on the left, it is the direct replacement for boats fitted from the factory with a 180 Ah battery of this format.

• Sealed: no spills or gases in the locker.
• Resistant to humidity and salt air.
• AGM: faster recharging and better cycle resistance than a conventional battery.
• Ready for starting outboard and inboard engines.

Will it fit your current battery tray?

It has external dimensions of 512 × 222 × 218 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. It uses EN terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

What the Fulbat FDM12-900 is for

The Fulbat FDM12-900 is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has EN terminals.

Technology inside the Fulbat FDM12-900

Fulbat builds the FDM12-900 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

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.

What Fulbat does differently

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.

Manufacturer's warranty

The Fulbat FDM12-900 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

How to make it last longer

At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.
