With 165 Ah at 6 V and 900 A of cold cranking current (EN), the Exide EU165-6 from the Marina Vintage range is built for motor and sailing boats, both for engine starting and onboard services. It measures 330 × 174 × 234 mm and the positive terminal on the right, the format sought by anyone replacing a 165 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.

Will it fit your current battery tray?

The Exide EU165-6 is made in the 330 × 174 × 234 mm format and weighs 25 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 B0 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.

What the Exide EU165-6 is for

With 165 Ah, the Exide EU165-6 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 25 kg, 1 terminals and B0 hold-down.

The Exide EU165-6: Marina Vintage range and conventional lead-acid technology

Within the Exide catalogue, the Marina Vintage series groups the references designed for this use. The EU165-6 is the 165 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.

Frequently asked questions

How do I fit the EU165-6 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 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 right 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 many years does this battery last?

Expected lifespan of the Exide EU165-6 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 size is this battery?

Dimensions (length × width × height) are 330×174×234 mm — also written as 330x174x234 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 EU165-6 model?

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.

Is the EU165-6 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 EU165-6 typically fits a wide range of European vehicles thanks to its standard DIN case format.

What are the equivalents of the EU165-6 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.
