With **26 Ah** at **12 V**, the **Fullriver DCG26-12** from the **DCG** range is built for motor and sailing boats, both for engine starting and onboard services. Its 165 × 176 × 125 mm make it the exact replacement for the 26 Ah battery fitted as standard to many boats.
- Ready for starting outboard and inboard engines.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Resistant to humidity and salt air.
- Sealed: no spills or gases in the locker.

### Size, terminals and hold-down of the Fullriver DCG26-12

The Fullriver DCG26-12 is made in the 165 × 176 × 125 mm format and weighs 9.10 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 the Fullriver DCG26-12 is for

The Fullriver DCG26-12 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 9.10 kg and M6 terminals.

### The Fullriver DCG26-12: DCG range and AGM technology

The DCG26-12 is part of the Fullriver **DCG** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.

### Why choose Fullriver batteries

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.

### Warranty and coverage

The Fullriver DCG26-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### Care and maintenance

Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

### When you get it and how to return it

Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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 DCG26-12 model AGM? What does this technology offer?

Yes. The DCG26-12 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.

### How is the Fullriver DCG26-12 battery installed in the vehicle?

In most boats it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How many years does this battery last?

Expected lifespan of the Fullriver DCG26-12 is 5 to 8 years in mild-climate boat use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the measurements of the DCG26-12 model?

Dimensions (length × width × height) are 165×176×125 mm — also written as 165x176x125 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.

### Will the Fullriver DCG26-12 battery fit my boat?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DCG26-12 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the DCG26-12 model?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level.
