Batteries are dieing like mad in the heat. For those that don't know you can substitute a group 48 for the group 47 that is the recommended size. It's a bit longer but fits into the tray just fine and in the case of autozone you go from 590 cold cranking amps to 700 CCA and it's only a dollar more (presently) Same warranty.
For those of us that are a little absent minded and leave a light on or a door ajar it gives you a bigger margin for getting back to the car and having enough left to still get it started. Not to mention a bit more cranking if you have a hard start problem or flood it
It's just a thought.

 

Cool beans i was looking for a way to get a more powerful battery for my car.
now i will be able to run the radio while I'm parked and not have to worry about it going dead.
