### What the Fullriver DC220-12 is for

The Fullriver DC220-12 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 66.50 kg and M8 terminals.

### Size, terminals and hold-down of the Fullriver DC220-12

The Fullriver DC220-12 is made in the 522 × 242 × 222 mm format and weighs 66.50 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 DC220-12: DC range and AGM technology

Within the Fullriver catalogue, the **DC** series groups the references designed for this use. The DC220-12 is the 220 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### Fullriver: the maker behind the DC220-12

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.

### Manufacturer's warranty

The Fullriver DC220-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### Care and maintenance

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

Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### Is the Fullriver DC220-12 an AGM battery and what are the benefits of AGM?

Yes. The DC220-12 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 are the measurements of the DC220-12 model?

Dimensions (length × width × height) are 522×242×222 mm — also written as 522x242x222 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.
