The Exide EZ650 marine battery offers 12 V, 75 Ah and 750 A of cold cranking current (EN) from the Marina Dual Ez range with EFB technology, designed for motor and sailing boats, both for engine starting and onboard services. Measuring 270 × 175 × 222 mm and the positive terminal on the left, it is the direct replacement for boats fitted from the factory with a 75 Ah battery of this format.
- EFB: the evolution of the conventional battery for basic Start-Stop cars.
- Ready for starting outboard and inboard engines.
- Sealed: no spills or gases in the locker.
- Resistant to humidity and salt air.
What the Exide EZ650 is for
On board, the Exide EZ650 provides 75 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 19 kg.
Size, terminals and hold-down of the Exide EZ650
It has external dimensions of 270 × 175 × 222 mm and weighs 19 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. 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 Exide does differently
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
The Exide EZ650: Marina Dual Ez range and EFB technology
Within the Exide catalogue, the Marina Dual Ez series groups the references designed for this use. The EZ650 is the 75 Ah model of that family, with the same performance as its siblings in other sizes.
EFB (Enhanced Flooded Battery) technology reinforces the conventional lead-acid battery with a polyester separator and carbon additives in the plates. It withstands many more start cycles and partial discharges, making it ideal for basic Start-Stop and intensive use.
How to make it last longer
At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. As a service battery, avoid routine discharges below 50% to extend its cycle life.
Manufacturer's warranty
The Exide EZ650 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.
Shipping, delivery and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 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 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

How to change the battery
Guide to replace a marine battery (cranking or house) in 20-30 minutes. Moisture and vibration in marine environments require reinforced hold-downs and sealed copper terminals.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery compartment
Usually under the passenger bench, engine room or a dedicated ventilated compartment. Verify the compartment is dry and well ventilated before opening.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Marine batteries are heavy (15-50 kg). If it has rope handles, use them; otherwise have a carry strap ready. Secure the new one with metal hold-downs (not plastic) to resist sea-state vibration.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify circuit + water protection
Apply dielectric grease on terminals to prevent salt-air corrosion. Check the engine charging circuit delivers 13.8-14.4 V at 2,000 rpm.
Frequently asked questions
Is the Exide EZ650 an EFB battery? When is EFB used?
Yes. The EZ650 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. Withstands more cycles than a conventional but fewer than an AGM. Fitted to boats with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years.
How is the Exide EZ650 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 many years does this battery last?
Expected lifespan of the Exide EZ650 is 4 to 6 years in basic Start-Stop boat use. 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 EZ650 model?
Dimensions (length × width × height) are 260×173×222 mm — also written as 260x173x222 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.
Does this 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 EZ650 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide EZ650?
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.
