Fulbat FDM12-700 · Marine battery 12V 140Ah 700A AGM CARBON

Marine battery Fulbat FDM12-700 140Ah 700A 12V

The Fulbat FDM12-700 marine battery offers 12 V, 140 Ah and 700 A of cold cranking current (EN) with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. Its 512 × 188 × 218 mm and the positive terminal on the left make it the exact replacement for the 140 Ah battery fitted as standard to many boats.

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

Size, terminals and hold-down of the Fulbat FDM12-700

In terms of format, the Fulbat FDM12-700 measures 512 × 188 × 218 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. It uses EN terminals, the system that anchors and connects it in the vehicle. 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.

What the Fulbat FDM12-700 is for

The Fulbat FDM12-700 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 FDM12-700

The FDM12-700 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.

What Fulbat does differently

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Manufacturer's warranty

The Fulbat FDM12-700 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up.

When you get it and how to return it
