This is an interesting thread.
But we must all keep in mind that the "nominal" 17 amp hours of the Odyssey
battery
(or of any other) is predicated on a 20 hour discharge rate and has an endpoint
of 11volts.
Therefore any discharge rate over one (1) amp will result in a battery capacity
of far under 17ah. At even at a 3 amp discharge rate a fresh Odyssey 17 ah
battery
will be perilously close to complete discharge after 3 hours.
Food for thought.
