If you read carefully, this document is a slightly exaggerated sales pitch.
Note that many of the comparisons are to Standard starting, lighting,
ignition (SLI) batteries, not true deep cycle. The discharge ratings are for
10 hours, not 5. The discharge voltage is 10.2, not 10.5 volts, etc.

And what is the warranty?

But Hawker claims an Odessey can be discharged essentially to zero
and recharged many times.  Other batteries was a maximun discharge
of 50%.

See:
http://www.odysseyfactory.com/documents/US-ODY-AM-001_0406.pdf
on page 10 for a German DIN test.

I switched from an Interstate starting battery to an Odessey last
winter because after a couple year's use, the starting battery
just couldn't deliver many amps.  I haven't had any troubles
with the Odessey, but only have 4-5 trips of experience so far.
This is for my aux battery.  You can also use an Odessey as a
starting AND deep cycle battery, similar to the Optima Yellowtop.
