Just saying, if you have to jump start your car after a week with a new battery you have a problem with something in the car drawing power, if you have a multimeter with 10A range take of the positive lead off and measure the standby current for your car, if it's way less than 1A that's OK but any more see an Auto Electrician, or get your "new battery" tested. How old is your battery? Of cause do this test before any re-installations.
