The **Fullriver DC26-12A** with AGM technology is a marine battery with **26 Ah** and **160 A** of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Its 166 × 126 × 174 mm make it the exact replacement for the 26 Ah battery fitted as standard to many boats.
- Resistant to humidity and salt air.
- Sealed: no spills or gases in the locker.
- Ready for starting outboard and inboard engines.
- AGM: faster recharging and better cycle resistance than a conventional battery.

### What the Fullriver DC26-12A is for

The Fullriver DC26-12A 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 10.10 kg and M5 terminals.

### Dimensions, polarity and mounting

In terms of format, the Fullriver DC26-12A measures 166 × 126 × 174 mm (length × width × height) and weighs 10.10 kg. It uses M5 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.

### What Fullriver does differently

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. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.

### The Fullriver DC26-12A: DC range and AGM technology

The DC26-12A 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.
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.

### Usage and maintenance tips

As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

### Manufacturer's warranty

The Fullriver DC26-12A comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### Delivery times and returns

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 DC26-12A model AGM? What does this technology offer?

Yes. The DC26-12A 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 DC26-12A 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 long does the Fullriver DC26-12A battery last?

Expected lifespan of the Fullriver DC26-12A 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 dimensions of the Fullriver DC26-12A battery?

Dimensions (length × width × height) are 166×126×174 mm — also written as 166x126x174 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 DC26-12A 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 DC26-12A typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Fullriver DC26-12A?

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.
