I've had horrible luck with batteries. My Z doesn't get driven much so the "sitting in the garage" does a number on batteries. It's common knowledge among anyone and everyone who has worked within a GM dealership that A/C Delco batteries are crap for a car that sits. If you drive your car every day, an A/C Delco battery will last a long time....... or at least until it starts leaking acid. A/C Delco batteries are the absolute worst about going bad if allowed to sit and lose a charge. 3 times and they are pretty much gone. My last replacement was just a few months ago with the top of the line Wally World "Maxx" battery. 3 months later, dead as can be, won't take a charge.

Has anyone thought about using a Marine battery ? Aren't marine batteries designed to stay charged longer on something that sits and doesn't get used ? I'm not sure what to buy now, have changed the damn battery too many times on the 'ol Z.
