Fullriver DC120-12B · Marine battery 12V 120Ah 760A AGM

Marine battery Fullriver DC120-12B DC 120Ah 760A 12V

With 120 Ah at 12 V and 760 A of cold cranking current (EN), the Fullriver DC120-12B from the DC range is built for motor and sailing boats, both for engine starting and onboard services. Measuring 331 × 175 × 218 mm, it is the direct replacement for boats fitted from the factory with a 120 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.

What the Fullriver DC120-12B is for

On board, the Fullriver DC120-12B provides 120 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 36.50 kg and M8 terminals.

Will it fit your current battery tray?

In terms of format, the Fullriver DC120-12B measures 331 × 175 × 218 mm (length × width × height) and weighs 36.50 kg. It uses M8 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.

The Fullriver DC120-12B: DC range and AGM technology

The DC120-12B is part of the Fullriver DC range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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 Fullriver does differently

With its own plants and a catalogue focused on high-performance AGM, Fullriver is a familiar brand in power wheelchairs, boats and photovoltaic systems that need thousands of cycles. 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 Fullriver DC120-12B 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

As a service battery, avoid routine discharges below 50% to extend its cycle life. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
