Unlike conventional batteries that need to be recharged every six to twelve weeks, the Odyssey battery will maintain up to 50% state of charge after 2 yrs if stored at room temperature (77ºF). At temperatures lower than 77°F, storage times will be evenlonger. The cranking power of Odyssey batteries is double to triple that of equally sized conventional batteries, even when the temperature is as low as -40ºF.
