Marine battery Exide EP900 Marina Dual EP 100Ah 800A 12V
The Exide EP900 with AGM technology is a marine battery with 100 Ah and 800 A of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Its 330 × 173 × 240 mm make it the exact replacement for the 100 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.
What the Exide EP900 is for
The Exide EP900 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 31.20 kg, SAE M 3/8"- 5/16"&stud terminals and B0 hold-down.
The Exide EP900: Marina Dual EP range and AGM technology
The Marina Dual EP is the Exide range the EP900 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.
Will it fit your current battery tray?
The Exide EP900 is made in the 330 × 173 × 240 mm format and weighs 31.20 kg. It uses a B0 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.
Exide: the maker behind the EP900
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. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Care and maintenance
As a service battery, avoid routine discharges below 50% to extend its cycle life. Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections.
Manufacturer's warranty
The Exide EP900 comes with the manufacturer's official warranty against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

Frequently asked questions
Is the EP900 model AGM? What does this technology offer?
Yes: the EP900 from Exide uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery.
Is this a starting or a service (leisure) battery?
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?
Being AGM, it is sealed and does not spill: it can be mounted tilted (never upside down) and copes well with vibration and wave impacts. Secure it firmly and keep the terminals away from water.
What are the dimensions of the Exide EP900 battery?
Measure your boat's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 330x173x240 mm. Height is measured to the top of the terminals.
Exide EP900 or Exide EM960: which one to choose?
Same range and the same performance as the EP900. Compared with the EP900 it has the same Ah and cranking power. It costs 43,75 € more. Either one works; decide by price.
