Marine battery Fullriver DCG170-12 DCG 170Ah 12V

The Fullriver DCG170-12 marine battery offers 12 V, 170 Ah from the DCG range with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. Measuring 381 × 178 × 352 mm, it is the direct replacement for boats fitted from the factory with a 170 Ah battery of this format.

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

What the Fullriver DCG170-12 is for

The Fullriver DCG170-12 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 a weight of 57.40 kg and M8 terminals.

Dimensions, polarity and mounting

In terms of format, the Fullriver DCG170-12 measures 381 × 178 × 352 mm (length × width × height) and weighs 57.40 kg. It uses M8 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

What Fullriver does differently

Fullriver specialises in deep-cycle AGM batteries for mobility, marine, solar and traction. Its DC and HC series are known for their tolerance to deep discharge and long cycle life. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Fullriver DCG170-12: DCG range and AGM technology

The DCG is the Fullriver range the DCG170-12 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

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.

Usage and maintenance tips

Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

Warranty and coverage

The Fullriver DCG170-12 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
