Sealed and maintenance-free. ## 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 12 V ⚡ Capacity 140 Ah C20 🔋 Cold cranking 795 A EN-1 📏 Dimensions 341×172×289 mm ⚙️ Technology AGM ⚖️ Weight 43,1 kg 🏷️ Model DC Series ## Description ## Marine battery Fullriver DC140-12 DC 140Ah 795A 12V 12*V* Voltage 140*Ah* Capacity 795*A* Cold cranking 43.10*kg* Weight The **Fullriver DC140-12 marine battery** offers **12 V**, **140 Ah** and **795 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. It replaces the original battery without adaptation in boats with a 344 × 172 × 283 mm format: same 140 Ah capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Reinforced case against vibration and swell. - Powers onboard services: lights, sounder, GPS, fridge. - Tolerates the daily cycling of a boat in season. ### What the Fullriver DC140-12 is for With 140 Ah, the Fullriver DC140-12 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 43.10 kg and AP terminals. ### The Fullriver DC140-12: DC range and AGM technology The DC140-12 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. ### Dimensions, polarity and mounting It has external dimensions of 344 × 172 × 283 mm and weighs 43.10 kg. It uses AP 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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### 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. ### Manufacturer's warranty The Fullriver DC140-12 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Shipping, delivery and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is this battery AGM? What is it for? Yes. The DC140-12 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 do I fit the DC140-12 model in my boat? 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 DC140-12 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 size is this battery? Dimensions (length × width × height) are 341×172×289 mm — also written as 341x172x289 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. ### Does this 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 DC140-12 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fullriver DC140-12? 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. ## Reviews - **Average rating**: 4.79 / 5 (30 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-05*
