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 design** built for boat swell and vibration - **Dual function** starts the engine and powers onboard services - **Sealed and safe** maintenance-free even when the boat rolls 🔌 Voltage 6 V ⚡ Capacity 250 Ah C20 🔋 Cold cranking 960 A EN-1 📏 Dimensions 262×181×283 mm ⚙️ Technology AGM ⚖️ Weight 34,5 kg 🏷️ Model DC Series ## Description ## Marine battery Fullriver DC250-6 DC 250Ah 960A 6V 6*V* Voltage 250*Ah* Capacity 960*A* Cold cranking 34.50*kg* Weight The **Fullriver DC250-6 marine battery** offers **6 V**, **250 Ah** and **960 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. Measuring 262 × 181 × 272 mm, it is the direct replacement for boats fitted from the factory with a 250 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. ### Will it fit your current battery tray? In terms of format, the Fullriver DC250-6 measures 262 × 181 × 272 mm (length × width × height) and weighs 34.50 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 the Fullriver DC250-6 is for With 250 Ah, the Fullriver DC250-6 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 34.50 kg and M8 terminals. ### The Fullriver DC250-6: DC range and AGM technology The DC250-6 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. ### Fullriver: the maker behind the DC250-6 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. 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 DC250-6 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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### When you get it and how to return it 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 the Fullriver DC250-6 an AGM battery and what are the benefits of AGM? Yes. AGM (Absorbent Glass Mat) technology, 250 Ah and 6 V: sealed lead-acid, with the electrolyte held in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### 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 dimensions of the Fullriver DC250-6 battery? Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 262×181×283 mm in length × width × height, with the terminals included in the height. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
