Sealed and maintenance-free. For onboard loads (fridge, sounder, lights) you also need a service battery. ## Why this marine starting battery? - **Marine design** built for boat swell and vibration - **Starting in demanding conditions** maximum cranking power - **Sealed and safe** maintenance-free even when the boat rolls 🔌 Voltage 12 V ⚡ Capacity 140 Ah C20 🔋 Cold cranking 800 A EN-1 📏 Dimensions 513×189×223 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the left ⚖️ Weight 34,1 kg 🏷️ Model EXIDE MARINA START ## Description ## Marine battery Exide EN900 Marina Start 140Ah 800A 12V 12*V* Voltage 140*Ah* Capacity 800*A* Cold cranking 34.10*kg* Weight The **Exide EN900 marine battery** offers **12 V**, **140 Ah** and **800 A** of cold cranking current (EN) from the **Marina Start** range with conventional lead-acid technology, designed for motor and sailing boats, both for engine starting and onboard services. It measures 513 × 189 × 223 mm and the positive terminal on the left, the format sought by anyone replacing a 140 Ah battery in boats. - Reinforced case against vibration and swell. - Conventional lead-acid: the most proven and economical technology. - Tolerates the daily cycling of a boat in season. - Powers onboard services: lights, sounder, GPS, fridge. ### What the Exide EN900 is for With 140 Ah, the Exide EN900 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 34.10 kg, 1 terminals and B0 hold-down. ### The Exide EN900: Marina Start range and conventional lead-acid technology The EN900 is part of the Exide **Marina Start** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Dimensions, polarity and mounting It has external dimensions of 513 × 189 × 223 mm and weighs 34.10 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B0 hold-down and 1 terminals, the system that anchors and connects it in the vehicle. 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. ### Why choose Exide batteries Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty. ### How to make it last longer Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. ### Official warranty The Exide EN900 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 Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 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 **14 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 a starting or a service (leisure) battery? Starting: it delivers a high current for a few seconds to crank the engine. On boats with two circuits the ideal is one starting battery and one service battery. ### In what position can it be installed on the boat? It must be mounted upright, firmly secured and in a ventilated compartment, because it gives off gases when charging. Keep the terminals away from salt water. ### What are the dimensions of the Exide EN900 battery? Dimensions (length × width × height) are 513×189×223 mm — also written as 513x189x223 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. ### What polarity does the Exide EN900 battery have? Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ## Compatible vehicles The Exide EN900 fits 6 vehicles (7 engine versions), including the Wauquiez Saloon 40/ 47 (1990–2025), Bavaria Yachtbau GmbH Bavaria Bavaria 30,33,37,39 (1990–2025), Najadvarvet AB Najad 355 (1990–2025) and Dufour Yachts Dufour 44 / 455 (1990–2025). | Make | Model | Engine | Years | |---|---|---|---| | Wauquiez | Saloon | [40/ 47](https://baterias.com/gb/boat-batteries/wauquiez/saloon/40-47) | 1990–2025 | | Bavaria Yachtbau GmbH | Bavaria | [Bavaria 30,33,37,39](https://baterias.com/gb/boat-batteries/bavaria-yachtbau-gmbh/bavaria/bavaria-30333739) | 1990–2025 | | Najadvarvet AB | Najad | [355](https://baterias.com/gb/boat-batteries/najadvarvet-ab/najad/355) | 1990–2025 | | Dufour Yachts | Dufour | [44 / 455](https://baterias.com/gb/boat-batteries/dufour-yachts/dufour/44-455) | 1990–2025 | | Wauquiez | Centurion | [40 S / 45 S](https://baterias.com/gb/boat-batteries/wauquiez/centurion/40-s-45-s) | 1990–2025 | | Bavaria Yachtbau GmbH | 38 Cruiser | [38 Cruiser](https://baterias.com/gb/boat-batteries/bavaria-yachtbau-gmbh/38-cruiser/38-cruiser) | 1990–2025 | | Bavaria Yachtbau GmbH | Bavaria | [40vision](https://baterias.com/gb/boat-batteries/bavaria-yachtbau-gmbh/bavaria/40vision) | 1990–2025 | ## Equivalent batteries - [VARTA LFD140](https://baterias.com/gb/battery-varta-lfd140-12v-140ah-800a) - [EXIDE ER660](https://baterias.com/gb/battery-exide-er660-12v-140ah-750a) - [EXIDE EP1200](https://baterias.com/gb/battery-exide-ep1200-12v-140ah-700a) ## 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*
