when i use the a/c when driving it sucks all the juice out of the battery, and after replacing one battery,I used the a/c again and it started draining the new battery, so after charging the battery back to 100% and putting it back in the car i have been driving with no a/c on and the battery light has stayed off.is there any way that there's something wrong with the a/c system and not the alternator?
If i turn my a/c on while driving the battery light comes on ,why? on 2007 Toyota Camry
Possible drive belt system problem! Any squealing noises with AC on? Need to know alt. output voltage.

poss alt is not putting out enough voltage to handle the load
