Measuring 138 × 86 × 102 mm, it is the direct replacement for boats fitted from the factory with a 8 Ah battery of this format. - AGM: faster recharging and better cycle resistance than a conventional battery. - Ready for starting outboard and inboard engines. - Sealed: no spills or gases in the locker. - Resistant to humidity and salt air. ### What the Fullriver FT100 is for With 8 Ah, the Fullriver FT100 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 3 kg and M6 terminals. ### The Fullriver FT100: Full Throttle Series range and AGM technology The FT100 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. 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 In terms of format, the Fullriver FT100 measures 138 × 86 × 102 mm (length × width × height) and weighs 3 kg. It uses M6 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. All the Fullriver batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### How to make it last longer At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### Manufacturer's warranty The Fullriver FT100 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 [[ks:cutoff]]** 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 **[[ks:return_days]] 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 FT100 an AGM battery and what are the benefits of AGM? Yes. The FT100 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 FT100 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 our blog. 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 FT100 battery last? Expected lifespan of the Fullriver FT100 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 FT100 battery? Dimensions (length × width × height) are 138×86×102 mm — also written as 138x86x102 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 FT100 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 FT100 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Fullriver FT100? 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. ## Equivalent batteries - [FULLRIVER FT100R](https://baterias.com/gb/battery-fullriver-ft100r-12v-8ah-100a) ## 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 · 2026-10-20*
