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 230 Ah C20 🔋 Cold cranking 1100 A EN-1 📏 Dimensions 518×274×240 mm ⚙️ Technology Lead-acid 🧭 Polarity Positive on the left ⚖️ Weight 64,8 kg 🏷️ Model EXIDE MARINA DUAL ET ## Description ## Marine battery Exide ET1600 Marina Dual Et 230Ah 1,100A 12V 12*V* Voltage 230*Ah* Capacity 1,100*A* Cold cranking 64.80*kg* Weight The **Exide ET1600 marine battery** offers **12 V**, **230 Ah** and **1,100 A** of cold cranking current (EN) from the **Marina Dual Et** range with conventional lead-acid 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 518 × 279 × 240 mm format: same 230 Ah capacity and the positive terminal on the left. - Powers onboard services: lights, sounder, GPS, fridge. - Tolerates the daily cycling of a boat in season. - Conventional lead-acid: the most proven and economical technology. - Reinforced case against vibration and swell. ### What the Exide ET1600 is for The Exide ET1600 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 64.80 kg, 1 terminals and B0 hold-down. ### Dimensions, polarity and mounting In terms of format, the Exide ET1600 measures 518 × 279 × 240 mm (length × width × height) and weighs 64.80 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. ### 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. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty. ### The Exide ET1600: Marina Dual Et range and conventional lead-acid technology Within the Exide catalogue, the **Marina Dual Et** series groups the references designed for this use. The ET1600 is the 230 Ah model of that family, with the same performance as its siblings in other sizes. The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop. ### Usage and maintenance tips As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. ### Warranty and coverage The Exide ET1600 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 is the Exide ET1600 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 long does the Exide ET1600 battery last? Expected lifespan of the Exide ET1600 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 ET1600 model? Dimensions (length × width × height) are 518×274×240 mm — also written as 518x274x240 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 ET1600 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 ET1600 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the ET1600 model? 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 N5](https://baterias.com/gb/battery-varta-n5-12v-220ah-1150a) - [VARTA N2](https://baterias.com/gb/battery-varta-n2-12v-200ah-1050a) - [VARTA LFD230](https://baterias.com/gb/battery-varta-lfd230-12v-230ah-1050a) ## 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 · 2026-10-07*
