Batteries two biggest enemies are extreme heat and cold. Batteries in cars that are in the south and the north will see the shortest life spans. They actually make batteries based on climates. If you get a battery in the north and move to Florida, chances are it will fail prematurely.

FYI, Interstates and Die Hard golds (there was a period of time that they were made by AC Delco) are both made by Johnson Controls. There really are only 3 battery companies in the US. Johnson Control, AC Delco, and Exide. They make pretty much every battery you will find. I personally would never buy an Exide made battery.
