Exide EP450 12V 50Ah 750A is a marine battery with reinforced anti-vibration case for moorings and offshore use. Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea.
Why this marine battery?
- Marine designbuilt for boat swell and vibration
- Dual functionstarts the engine and powers onboard services
- Sealed and safemaintenance-free even when the boat rolls
Marine battery Exide EP450 Marina Dual EP 50Ah 750A 12V
With 50 Ah at 12 V and 750 A of cold cranking current (EN), the Exide EP450 from the Marina Dual EP range is built for motor and sailing boats, both for engine starting and onboard services. Its 260 × 173 × 206 mm make it the exact replacement for the 50 Ah battery fitted as standard to many boats.
- Ready for starting outboard and inboard engines.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Resistant to humidity and salt air.
- Sealed: no spills or gases in the locker.
Size, terminals and hold-down of the Exide EP450
The Exide EP450 is made in the 260 × 173 × 206 mm format and weighs 18.60 kg. It uses a B7 hold-down and SAE M 3/8"- 5/16"&stud 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 EP450 is for
The Exide EP450 is designed for motor and sailing boats, both for engine starting and onboard services. If it is your starter battery, run the services from a separate battery; if it is a service battery, avoid routinely discharging it beyond 50%. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 18.60 kg, SAE M 3/8"- 5/16"&stud terminals and B7 hold-down.
The Exide EP450: Marina Dual EP range and AGM technology
The Marina Dual EP is the Exide range the EP450 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.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
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 EP450 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
Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. As a service battery, avoid routine discharges below 50% to extend its cycle life.
Shipping, delivery and returns
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
Is the Exide EP450 an AGM battery and what are the benefits of AGM?
Yes. The EP450 from Exide uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How do I fit the EP450 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 — 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 long does the Exide EP450 battery last?
Expected lifespan of the Exide EP450 is 5 to 8 years in mild-climate boat use with 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 are the dimensions of the Exide EP450 battery?
Dimensions (length × width × height) are 260×173×206 mm — also written as 260x173x206 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.
Will the Exide EP450 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 EP450 typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Exide EP450?
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.
