The Fullriver DC50-12B in practice
DC50-12B vs Fullriver DC60-12
The Fullriver DC50-12B offers 50 Ah and 270 A cold cranking in a 198 × 166 × 171 mm case. The Fullriver DC60-12, same brand and technology, goes up to 60 Ah and 410 A with 67 mm more length and costs €54.40 more. The difference shows on diesels and in hard winters; for a daily-driven petrol car the extra is not needed.

- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
What the Fullriver DC50-12B is for
On board, the Fullriver DC50-12B provides 50 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 14.90 kg and M6 terminals.
The Fullriver DC50-12B: DC range and AGM technology
The DC is the Fullriver range the DC50-12B 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.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.
Dimensions, polarity and mounting
In terms of format, the Fullriver DC50-12B measures 198 × 166 × 170 mm (length × width × height) and weighs 14.90 kg. It uses M6 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
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.
Official warranty
The Fullriver DC50-12B comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Frequently asked questions
Is the Fullriver DC50-12B an AGM battery and what are the benefits of AGM?
Yes. The Fullriver DC50-12B is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. 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 dimensions of the Fullriver DC50-12B battery?
Its dimensions are 198×166×171 mm, also written 198x166x171 mm; the height already includes the terminals. Check the room available in your boat, because a single millimetre too much can stop the clamp from closing.
