Dead battery

My battery dies every week or two. I've had the car checked multiple times and have bought 4 new batteries in two years. I'm told the alternator is fine. No one can seem to find the battery drain . I've been to 2 different mechanics. The last mechanic replaced a "light module" . Car did fine for almost one month before it died again. Does anyone have any suggestions?

Do u mean it sits for a week or 2 then wont start or you use it everyday and it's dead one morning? Never heard of a light module // but I've seen some really heavy ones

Sounds like you have a parasitic draw on the battery. Have your mechanic check for a parasitic draw.

Thank you. I'd never heard of a light OR heavy module. :) It is dead after it sits without being driven for a few days. Both mechanics have claimed to check for parasitic draws. I have paid approximately 900.00 so far for various "fixes" . Yet, here it sits....

Here is a sight on how that is done... https://www.youtube.com/watch?v=QRso1A0VScw
