The ODYSSEY® Drycell battery combines in one box the characteristics of two separate batteries. It can deep cycle as well as provide enormous cranking power. These dry cell batteries are capable of providing engine cranking pulses in excess of 2150A for 5 seconds as well as 400 charge/discharge cycles to 100% depth of discharge (DOD). A typical starting, lighting and ignition (SLI) battery can do one or the other, but not both. Conventional batteries are either a sprinter or a long distance runner; An ODYSSEY® battery will do both — provide short duration high amperage pulse or low rate long duration drains.
