The Exide ER570 is made in the 349 × 175 × 235 mm format 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Exide ER570 is for On board, the Exide ER570 provides 120 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. ### The Exide ER570: Marina Dual Er range and conventional lead-acid technology The **Marina Dual Er** is the Exide range the ER570 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. 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. ### Why choose Exide batteries With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe.

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 measurements of the ER570 model? The Exide ER570 takes up 349×175×235 mm (length, width and height, terminals included). Before buying, measure the space in your boat: one extra millimetre can stop the hold-down clamp from closing. ### On which side is the positive of the ER570 model? Polarity of the Exide ER570: positive on the left. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. ### Exide ER570 or Exide ER550: which one to choose? Same case and same technology as the ER570: an alternative by size, not an official equivalent. Compared with the ER570 it has 5 Ah less. It costs the same. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ### Exide ER570 or Exide EN850: which one to choose? It has the same dimensions, voltage and technology as the ER570, although it is not a manufacturer-approved equivalent. Compared with the ER570 it has 10 Ah less and 10 A of cold cranking less. It costs 8,70 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ## 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 · 2026-11-07*
