It replaces the original battery without adaptation in boats with a 349 × 175 × 235 mm format: same 115 Ah capacity and the positive terminal on the left. - Conventional lead-acid: the most proven and economical technology. - Reinforced case against vibration and swell. - Powers onboard services: lights, sounder, GPS, fridge. - Tolerates the daily cycling of a boat in season. ### What the Exide ER550 is for On board, the Exide ER550 provides 115 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 27.80 kg, 1 terminals and B0 hold-down. ### Dimensions, polarity and mounting It has external dimensions of 349 × 175 × 235 mm and weighs 27.80 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. ### The Exide ER550: Marina Dual Er range and conventional lead-acid technology The ER550 is part of the Exide **Marina Dual Er** range.

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 dimensions of the Exide ER550 battery? It measures 349×175×235 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Which side is the positive terminal on this battery? Polarity of the Exide ER550: positive on the left. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Seen from the front, terminals towards you, the positive (+) is the post with the red ring. ### Exide ER550 or Varta LFS120: which one to choose? Same case and same fitting as the ER550, from Varta. Compared with the ER550 it has 5 Ah more and 20 A of cold cranking more. It costs 167,10 € more. If you want to save or the ER550 is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty. ## Equivalent batteries - [VARTA LFS120](https://baterias.com/gb/battery-varta-lfs120-12v-120ah-680a) ## 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 · 2026-11-13*
