A vehicle battery will actually start to discharge on its own within 24 hours in hot weather. It takes several days in cold weather. When batteries are left too long in a state of partial discharge, the discharged portion of the battery plates for the lack of a better word 'die.' Recharging the battery will not restore the dead part of the battery plate.
Batteries are fairly expensive, so taking a few steps to make them last longer is well worth it. Of course, the battery will eventually need to be replaced. Always make sure you get a new battery that meets the factory specifications for your vehicle. If you feel you need more battery capacity than what came with your vehicle, talk with your service advisor about appropriate upgrades.
