Odyssey PC1200 is a deep cycle drycell AGM battery designed to deliver 1200CA (Cranking Amps) and 550CCA (Cold Cranking Amps). With a 42Ah in capacity, PC1200 is a "true" deep cycle high cranking battery. Odyssey batteries use pure lead in its construction, thus giving it a superior design above all other batteries. This allows the battery to put out tremendous cranking power while having the ability to completely discharge and recharge over 400 times. In addition, pure lead plates are resistant to sulfation and corrosion - the number one cause of battery failure.Specs1200CA for 5 seconds 1090CA for 10 seconds
