I didn't think anyone thought the deep cycle batteries lasted longer...just had heard (from the Corvette guys) that if you have a glass mat type battery (like I got in my 2001 C5) that the batteries last less if they aren't properly cared for i.e: driven or using something like a battery tender...since sometimes cars like our GTOs and those Corvettes are not daily drivers, the batteries not being used might fail from not being used...some have argued this was the reason that GM went away from the AGM batteries in their cars, specifically the Corvette...

You got me on that one. I can't vouch for or against GM having swapped batteries, except for the GTO and Vette, which as you correctly pointed out, don't have the traditional AC delco found in the rest of the fleet. The post pattern is different. Anyone know specifically why, and what other cars have the non-gm post pattern? It'd be interesting to get some insight on this issue.

This problem, of batteries draining is more common that might be imagined. VW was having this problem with the "new" Bug. Again, the end result is the intended use of the battery. If it's used/maintained properly, "most" batteries will perform just fine for a number of years. If left on their own, well... some just do better than others. Anyone seen a MBZ battery lately? I kindly refer to those things as the "yard stick". Those sit for quite some time, fire right up... pretty amazing for OEM equipment.
