Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea. ## 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 100 Ah C20 🔋 Cold cranking 800 A EN-1 📏 Dimensions 353×175×190 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ⚖️ Weight 26,5 kg 🏷️ Model EXIDE MARINA DUAL ET ## Description ## Marine battery Exide ET650 Marina Dual Et 100Ah 800A 12V 12*V* Voltage 100*Ah* Capacity 800*A* Cold cranking 26.50*kg* Weight The **Exide ET650** with conventional lead-acid technology is a marine battery with **100 Ah** and **800 A** of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. It measures 353 × 175 × 190 mm and the positive terminal on the right, 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. - Conventional lead-acid: the most proven and economical technology. ### What the Exide ET650 is for The Exide ET650 is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 26.50 kg, 1 terminals and B13 hold-down. ### Dimensions, polarity and mounting In terms of format, the Exide ET650 measures 353 × 175 × 190 mm (length × width × height) and weighs 26.50 kg. The positive terminal on the right 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 B13 hold-down and 1 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. ### Why choose Exide batteries 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### The Exide ET650: Marina Dual Et range and conventional lead-acid technology The **Marina Dual Et** is the Exide range the ET650 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. 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. ### How to make it last longer As a service battery, avoid routine discharges below 50% to extend its cycle life. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Manufacturer's warranty The Exide ET650 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### When you get it and how to return it 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? Dual purpose: it can start the engine and also work as a service battery, handy on boats with a single battery. 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 measurements of the ET650 model? Dimensions (length × width × height) are 353×175×190 mm — also written as 353x175x190 mm and correspond to the European L5 case size — 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 ET650 battery have? Polarity: positive on the right. 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 ET650 fits 2 vehicles (3 engine versions), including the Hanse Yachten Hanse 630e (1990–2025), Hanse Yachten Hanse 540e (1990–2025) and Hymer B-Klasse B Typ (1990–2025). | Make | Model | Engine | Years | |---|---|---|---| | Hanse Yachten | Hanse | [630e](https://baterias.com/gb/boat-batteries/hanse-yachten/hanse/630e) | 1990–2025 | | Hanse Yachten | Hanse | [540e](https://baterias.com/gb/boat-batteries/hanse-yachten/hanse/540e) | 1990–2025 | | Hymer | B-Klasse | [B Typ](https://baterias.com/gb/batteries-for-caravans/hymer/b-klasse/b-typ) | 1990–2025 | ## Equivalent batteries - [EXIDE EZ850](https://baterias.com/gb/battery-exide-ez850-12v-100ah-850wh-900a) ## 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 · 2026-10-29*
