So I'm traveling for work quite a bit and twice now within a month I come home to a dead battery. I have a 2004 with 32k miles and the only mods are audiolink iPod connector and RB sway bars. The first time it happened I assumed the OE battery was worn out so I replaced it with a comparable Costco battery. Now that my brand-new battery is also dead after not being driven for two weeks I'm wondering if there's something draining the battery. I obviously could have gotten a lemon from Costco but I wanted to see if anyone else has experienced this.

Any help is appreciated. Thanks.

Check the dark current.

but I would not trust a Costco Battery. go get a refund if possible. Get other brand battery.
