Collection: Applications: Motorcycle & Scooter Starting

NAIONICS EverStart sodium cranking batteries for motorcycles and scooters: 12V 3.5Ah with 70A CCA for 50cc scooters, 4.5Ah with 90A CCA for mopeds and bikes up to 125cc, 7Ah with 140A CCA for 100 to 150cc scooters, and larger sizes for bigger engines.

Part numbers follow the traditional motorcycle battery naming (YTX4A, 12N7, 12N9, 12N12), so replacement is direct: compare the code on the existing battery and check the cranking power in CCA the engine needs, not the capacity in Ah.

The practical gain on a bike is the weight, down by more than half, and how it holds over the winter: a sodium battery does not sulphate and starts again after months.
