2006 cobalt battery drains in 3 days of just sitting
Has the battery been tested? It might be going bad. Another possibility is a “parasitic draw.” Something might be draining the battery even while the ignition is off. A good shop can test for that. If you’re so inclined, you can pull fuses one at a time and see if the problem goes away. If it does, you’ve found the source of the draw.
