2006 impala SS idle

Will idling a 2006 impala ss for prolonged times in park (3-4 hours)
with only minimal accessories on cause the battery to discharge and the
check battery light to come on. In other words how much output is the
alternator producing under these conditions?

The output should remain steady at 14+ volts at idle, but extreme temps
caused by extended idling (and I'm assuming the A/C is on, yes?) could
cause the alternator's output to decrease a bit...and if the A/C is on,
you are providing high amps to the A/C compressor clutch and two
radiator fans plus the blower motor, and the fuel pump, ECM, fuel
injectors, there's a lotta electrical on cars anymore... one of the
reasons police versions have an upgraded unit...

Curious, why would you want to idle a motor that long? Bad idea:nono:
