Brand: EXIDE batteries Part number: EN850

Exide EN850 12V 110Ah 750A is a marine starting battery: it delivers the cranking power the engine needs and withstands vibration and swell on board. Sealed and maintenance-free. For onboard loads (fridge, sounder, lights) you also need a service battery.

Why this marine starting battery?

  • Marine designbuilt for boat swell and vibration
  • Starting in demanding conditionsmaximum cranking power
  • Sealed and safemaintenance-free even when the boat rolls

The Exide EN850 with conventional lead-acid technology is a marine battery with 110 Ah and 750 A of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Measuring 349 × 175 × 235 mm and the positive terminal on the left, it is the direct replacement for boats fitted from the factory with a 110 Ah battery of this format.

In short: the Exide EN850 (110 Ah, 750 A, 349 × 175 × 235 mm, positive terminal on the left). Verified equivalent alternatives: Exide ER550 and Varta LFS120.

  • Sealed: no spills or gases in the locker.
  • Resistant to humidity and salt air.
  • Good balance of capacity, cranking power and price.
  • Ready for starting outboard and inboard engines.

What the Exide EN850 is for

On board, the Exide EN850 provides 110 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 25.40 kg, 1 terminals and B0 hold-down.

Dimensions, polarity and mounting

The Exide EN850 is made in the 349 × 175 × 235 mm format and weighs 25.40 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 EN850: Marina Start range and conventional lead-acid technology

The Marina Start is the Exide range the EN850 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.

What Exide does differently

Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. We guarantee that every Exide arrives new, charged and with the manufacturer's full warranty.

Warranty and coverage

The Exide EN850 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

How to make it last longer

On batteries with filler caps, check the electrolyte level and top up only with distilled water. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.

When you get it and how to return it

Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions

How is the Exide EN850 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.

How many years does this battery last?

Expected lifespan of the Exide EN850 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 349×175×235 mm — also written as 349x175x235 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 EN850 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.

Will the Exide EN850 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 EN850 typically fits a wide range of European vehicles thanks to its standard DIN case format.

What are the equivalents of the EN850 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.
