I was thinking of getting one of these batteries http://www.jbccoffroad.com/procoba.html <yes I suck at doing the html stuff so it shows up as word you click on. (note: they cost less from 4wd.com; the starting battery at $120)

What makes the 'staring' battery different from the others, besides CCA and other specs, since it's less expensive than the 'off road' and 'marine' (deep cycle) battery.

I might spend some time at the parts store measuring batteries to figure out if I could get more than the current (dead) battey's 540cca.  More amps=quicker start, right?  I plan on upgrading battery cables as well.

Thanks!
