IF I DON'T DRIVE MY VIBE EVERY DAY THE BATTERY DIES on 2005 Pontiac Vibe

I JUST PURCHASED AN '05 VIBE ABOUT 3 WEEKS AGO. IT RAN FINE UNTIL LAST WEEK. IF I DON'T START IT UP EVERY DAY THE BATTERY DIES AFTER SITTING 2 DAYS. THE MECHANIC SAYS THE BATTERY TESTS NEW, THE ALTERNATER IS FINE, THE STARTER IS FINE. WHERE IS THE ELECTRICAL LEAK? HOW DO I FIND IT? THANKS, MS PRIEM

battery could be giving a flase test if the lead has fallen off the plates it sits on the bottom and gives off impression of good battery replace it if its over 3yrs old. also to help u can have him test for dark current ie parristic drain.
