...as a matter of fact we know about this...that's how come your idle speed and RPM's increase to compensate whenever your A/C is engaged...check activation of your "idle-up" solenoid~

Your performance will be cut by at least 12% whenever the a/c compressor is engaged...models without a/c will have a smaller engine typically~

It seems as though the I haven't posed this question/problem correctly.

NO. The battery drains down to nothing and alternator stops charging when a/c is on even at highway speed.

your battery has to be newer than fiver years old or will not be takin' a charge then as batteries stop taking a charge 10% per year, and will continue to ask for maximum output thusly cooking the alternator...so in conclusion...get a new battery...get a new alternator belt...and if needed at this point...get a new alternator~
