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 6 V ⚡ Capacity 140 Ah C20 🔋 Cold cranking 900 A EN-1 📏 Dimensions 257×175×236 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the right ⚖️ Weight 18,4 kg 🏷️ Model EXIDE MARINA VINTAGE ## Description ## Marine battery Exide EU140-6 Marina Vintage 140Ah 900A 6V 6*V* Voltage 140*Ah* Capacity 900*A* Cold cranking 18.40*kg* Weight With **140 Ah** at **6 V** and **900 A** of cold cranking current (EN), the **Exide EU140-6** from the **Marina Vintage** range is built for motor and sailing boats, both for engine starting and onboard services. It measures 257 × 175 × 236 mm and the positive terminal on the right, the format sought by anyone replacing a 140 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 EU140-6 is for The Exide EU140-6 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 18.40 kg, 1 terminals and B1 hold-down. ### The Exide EU140-6: Marina Vintage range and conventional lead-acid technology Within the Exide catalogue, the **Marina Vintage** series groups the references designed for this use. The EU140-6 is the 140 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Size, terminals and hold-down of the Exide EU140-6 The Exide EU140-6 is made in the 257 × 175 × 236 mm format and weighs 18.40 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 B1 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 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. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### How to make it last longer On batteries with filler caps, check the electrolyte level and top up only with distilled water. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### Manufacturer's warranty The Exide EU140-6 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 [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How do I fit the EU140-6 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 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. ### What is the service life of the EU140-6 model? Expected lifespan of the Exide EU140-6 is 4 to 6 years in regular boat use without 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 Exide EU140-6 battery? Dimensions (length × width × height) are 257×175×236 mm — also written as 257x175x236 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 EU140-6 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 EU140-6 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Exide EU140-6? 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 - [VARTA K13](https://baterias.com/gb/battery-varta-k13-12v-140ah-720a) ## Reviews - **Average rating**: 4.8 / 5 (31 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-29*
