2007 Pontiac Torrent

Electrical problem
2007 Pontiac Torrent 6 cyl All Wheel Drive Automatic 52000 miles

Every once in a while when I go out to start the car the battery is dead. I don't appear to be leaving any electrical devices on when I turn the car off or any interior lights on. After recharging battery everything is fine for a couple weeks or so then it happens again.

Battery is one year old, Replaced after lightning strike that knocked out $4,500 worth of electronics. Everything works fine except the battery goes dead occasionally. Thanks for your help.
