a light that's shaped like battery comes on the dash after a couple of days of sitting. I can start the car but scared that if I don't drive a couple of days battery will go bad. What can run battery down when sitting with everything turned off?

    dead short. Take neg. battery cabble loose and hook meter one lead to batt and other to cable. If reads voltage take one fuse out at a time until voltage drops to zero. That fuse will tell you what circuit the short is in.

    Have a MECHANIC check it out not a parts store for alternator output under load, battery draw test with the propper test equipment. Always some drain on the battery for keep alive componets ie computer, clock, radio ect. But should take weeks to run it down without driving.
    If it were a dead short there would be smoke and stuff melting or fuses blowing! Any add on equipment? Also that battery light, is it ever on while the engine is running?

    At that time it's output is enough to run the engine however it still may not be charging!
    Not a good idea to remove the battery cable with engine running, ECM provides the regulator for the alt. voltage!!!
    Get a mechanic to test the alt. voltage output, not a parts store.
