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 180 Ah C20 🔋 Cold cranking 1000 A EN-1 📏 Dimensions 513×223×223 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the left ⚖️ Weight 42,8 kg 🏷️ Model EXIDE MARINA START ## Description ## Marine battery Exide EN1100 Marina Start 180Ah 1,000A 12V 12*V* Voltage 180*Ah* Capacity 1,000*A* Cold cranking 42.80*kg* Weight The **Exide EN1100 marine battery** offers **12 V**, **180 Ah** and **1,000 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. Its 513 × 223 × 223 mm and the positive terminal on the left make it the exact replacement for the 180 Ah battery fitted as standard to many boats. - Resistant to humidity and salt air. - Sealed: no spills or gases in the locker. - Ready for starting outboard and inboard engines. - Good balance of capacity, cranking power and price. ### Will it fit your current battery tray? It has external dimensions of 513 × 223 × 223 mm and weighs 42.80 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. ### What the Exide EN1100 is for The Exide EN1100 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 42.80 kg, 1 terminals and B0 hold-down. ### The Exide EN1100: Marina Start range and conventional lead-acid technology The **Marina Start** is the Exide range the EN1100 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. ### Exide: the maker behind the EN1100 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. ### Warranty and coverage The Exide EN1100 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### Usage and maintenance tips 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. ### 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 ### How is the Exide EN1100 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 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 — with positive on the left 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 EN1100 model? Expected lifespan of the Exide EN1100 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 measurements of the EN1100 model? Dimensions (length × width × height) are 513×223×223 mm — also written as 513x223x223 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. ### On which side is the positive of the EN1100 model? 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. ### Is the EN1100 valid for my vehicle? 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 EN1100 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? 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 - [EXIDE ET1300](https://baterias.com/gb/battery-exide-et1300-12v-180ah-900a) - [EXIDE EP1500](https://baterias.com/gb/battery-exide-ep1500-12v-180ah-900a) - [VARTA M12](https://baterias.com/gb/battery-varta-m12-12v-180ah-1400a) ## 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 · 2026-10-28*
