- Tolerates the daily cycling of a boat in season.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Reinforced case against vibration and swell.
What the Fullriver DC115-12B is for
On board, the Fullriver DC115-12B provides 115 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 32.90 kg and M8 terminals.
Size, terminals and hold-down of the Fullriver DC115-12B
It has external dimensions of 331 × 175 × 218 mm and weighs 32.90 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.
Fullriver: the maker behind the DC115-12B
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.
The Fullriver DC115-12B: DC range and AGM technology
Within the Fullriver catalogue, the DC series groups the references designed for this use. The DC115-12B is the 115 Ah model of that family, with the same performance as its siblings in other sizes.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
Care and maintenance
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.
Manufacturer's warranty
The Fullriver DC115-12B comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
Shipping, delivery and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is this battery AGM? What is it for?
Yes, it is AGM. In an AGM battery such as the DC115-12B, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It withstands more cycles than a conventional battery and copes better with heat.
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 are the measurements of the DC115-12B model?
Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing. The Fullriver DC115-12B takes up 331×171×218 mm (length, width and height, terminals included).
