Collection: Applications: Marine Starting Batteries for Inboard/Outboard Diesel & Petrol Engines

NAIONICS EverStart sodium batteries for cranking combustion marine engines: 12V 20Ah with 460A CCA for petrol inboards up to 6 litres and diesels up to 4 litres, 30Ah with 600A CCA for outboards from 60 to 200 hp, 50Ah with 800A CCA from 200 to 350 hp, 60Ah with 900A CCA above 350 hp, up to the 24V 75Ah with 1000A CCA and Bluetooth for 4 to 8 litre diesels.

Choice is made on inboard displacement or outboard horsepower, not on capacity: it is cranking power in CCA that starts a cold diesel. Every model states exact dimensions so you can check the locker.

Sodium chemistry is unfazed by salt humidity and by long winter lay-ups, where a lead battery sulphates and loses cranking power.
