Its built-in BMS protects it against overcharge, over-discharge and short circuit. ## Why this lithium marine battery? - **Deep-cycle service bank** daily discharges to 80 % with no capacity loss - **60 % less weight on board** the same energy as lead-acid in far less space - **Built-in BMS, maintenance free** protects against overcharge, over-discharge and short circuit 🔌 Voltage 38 V ⚡ Capacity 100 Ah C20 📏 Dimensions 520×269×221 mm ⚙️ Technology LifePo4 BT 🧭 Polarity Positive on the right ⚖️ Weight 39 kg 🏷️ Model EXIDE MARINE AND LEISURE LI-Ion ## Description ## Marine battery Exide EV3800/36 MARINE AND LEISURE LI-Ion 100Ah 38.4V 38.4*V* Voltage 100*Ah* Capacity 39*kg* Weight The **Exide EV3800/36 marine battery** offers **38.4 V**, **100 Ah** from the **MARINE AND LEISURE LI-Ion** range with LiFePO4 lithium 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 520 × 269 × 221 mm format: same 100 Ah capacity. - Powers onboard services: lights, sounder, GPS, fridge. - Tolerates the daily cycling of a boat in season. - LiFePO4 lithium: minimal weight and almost zero self-discharge. - Reinforced case against vibration and swell. ### What the Exide EV3800/36 is for On board, the Exide EV3800/36 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 39 kg. ### Dimensions, polarity and mounting It has external dimensions of 520 × 269 × 221 mm and weighs 39 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### The Exide EV3800/36: MARINE AND LEISURE LI-Ion range and LiFePO4 lithium technology Within the Exide catalogue, the **MARINE AND LEISURE LI-Ion** series groups the references designed for this use. The EV3800/36 is the 100 Ah model of that family, with the same performance as its siblings in other sizes. LiFePO4 chemistry is the safest of the lithium batteries: thermally stable, cobalt-free and good for thousands of cycles, protected by its electronic management system. ### Exide: the maker behind the EV3800/36 With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Exide EV3800/36 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Care and maintenance As a service battery, avoid routine discharges below 50% to extend its cycle life. Store the battery at 50-70% charge if it will be unused for months. ### Shipping, delivery 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 ### How is the Exide EV3800S/36 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 Exide EV3800S/36 is 10 to 15 years, equivalent to 3,000-5,000 cycles at 80% DoD. 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 Exide EV3800S/36 battery? Dimensions (length × width × height) are 520×269×221 mm — also written as 520x269x221 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 Exide EV3800S/36 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 EV3800S/36 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide EV3800S/36? 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-08*
