With a brand-new battery, you can park your car for two weeks and the battery should still have ample charge. You should turn any energy-using devices off or unplugged before leaving your car sitting that long. If the car will sit a year or longer, disconnect the battery completely, and if it will sit at 25°c temperature or colder, the battery should be removed and taken indoors, but not near any heat like appliances or radiators.

Take care of the battery according to the car manufacturer or the battery manufacturer instructions, and your battery should last for a minimum of two years, on the average five years.
