cant beat the technology in the Enersys batteries. I suggest the Odyssey brand (consumer) vs Hawker (Commercial / Military) because of cost to the average person
The current enersys uses the same AGM technology that went into the spiral cell Optima (prior to Optima being sold to JCI and now cost-reduced to a poor performer), however in a dense packed stack that out performs the spiral cells as far as power/space available.
here is a chart
