It measures 307 × 169 × 237 mm, the format sought by anyone replacing a 100 Ah battery in boats. - Tolerates the daily cycling of a boat in season. - Powers onboard services: lights, sounder, GPS, fridge. - Reinforced case against vibration and swell. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. ### What the Fullriver FT965-27 is for On board, the Fullriver FT965-27 provides 100 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 31.60 kg and DT terminals. ### The Fullriver FT965-27: Full Throttle Series range and AGM technology The FT965-27 is part of the Fullriver **Full Throttle Series** 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. ### Dimensions, polarity and mounting It has external dimensions of 307 × 169 × 237 mm and weighs 31.60 kg. It uses DT 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. ### Care and maintenance Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. As a service battery, avoid routine discharges below 50% to extend its cycle life. ### Manufacturer's warranty The Fullriver FT965-27 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 Orders placed **before 6:00 pm** with the battery in stock ship the same day.

The FT965-27 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 dimensions of the Fullriver FT965-27 battery? Dimensions (length × width × height) are 307×169×237 mm — also written as 307x169x237 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. ### Fullriver FT965-27 or Fullriver FT965-27F: which one to choose? Same range and the same performance as the FT965-27. Compared with the FT965-27 it has the same Ah and cranking power. It costs 273,10 € more. Either one works; decide by price. ## Equivalent batteries - [FULLRIVER FT965-27F](https://baterias.com/gb/battery-fullriver-ft965-27f-12v-100ah-965a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-02*
