Fullriver DC145-12 12V 145Ah 820A is a marine battery with reinforced anti-vibration case for moorings and offshore use. Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea.
Why this marine battery?
- Marine designbuilt for boat swell and vibration
- Dual functionstarts the engine and powers onboard services
- Sealed and safemaintenance-free even when the boat rolls
Where it fits: the Fullriver DC145-12 is one of our boat batteries, belongs to our Fullriver batteries and by capacity it sits among our 145Ah batteries.

Marine battery Fullriver DC145-12 DC 145Ah 820A 12V
The Fullriver DC145-12 marine battery offers 12 V, 145 Ah and 820 A of cold cranking current (EN) from the DC range with AGM technology, designed for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 341 × 173 × 287 mm format: same 145 Ah capacity.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Reinforced case against vibration and swell.
- Powers onboard services: lights, sounder, GPS, fridge.
- Tolerates the daily cycling of a boat in season.
What the Fullriver DC145-12 is for
With 145 Ah, the Fullriver DC145-12 covers motor and sailing boats, both for engine starting and onboard services. At the end of the season, charge it fully before winter storage. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 44.30 kg and M8 terminals.
Size, terminals and hold-down of the Fullriver DC145-12
In terms of format, the Fullriver DC145-12 measures 341 × 173 × 287 mm (length × width × height) and weighs 44.30 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 DC145-12: DC range and AGM technology
Within the Fullriver catalogue, the DC series groups the references designed for this use. The DC145-12 is the 145 Ah model of that family, with the same performance as its siblings in other sizes.
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.
Fullriver: the maker behind the DC145-12
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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Manufacturer's warranty
The Fullriver DC145-12 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
At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
Shipping, delivery and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe.

Frequently asked questions
Is the DC145-12 model AGM? What does this technology offer?
Yes. The DC145-12 from Fullriver uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
In what position can it be installed on the boat?
Being AGM, it is sealed and does not spill: it can be mounted tilted (never upside down) and copes well with vibration and wave impacts. Secure it firmly and keep the terminals away from water.
What size is this battery?
Dimensions (length × width × height) are 341×173×287 mm — also written as 341x173x287 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
