The Odyssey battery ingeniously
uses absorbed glass mat (AGM) technology to offer, in one box, the
characteristics of two separate batteries. It can deep cycle as
well as provide enormous cranking power.
These batteries are capable of providing
engine cranking pulses in excess of 2250A for 5 seconds as well
as 400 charge/discharge cycles to 80% depth of discharge (DOD).
A typical starting, lighting and ignition (SLI) battery can do one
or the other, but not both.
Odyssey batteries will do both - provide
short duration high amperage pulse or low rate long duration drains.
