[QUOTE="jrz126, post: 1225443, member: 556466"] Can you really say that the battery doesn't do anything when there is a large load present? Yes the alt is responsible for charging the battery and also supplys power when the car is running. Under a load, the voltage will drop, and if it drops below the battery voltage, then it will start discharging the battery. Also, the current consumption will not increase when the voltage drops. I=V/R, the resistance of the load stays the same, as the voltage drops, the current will also decrease. And lastly, power is what causes heat, P=V*I. [/QUOTE]
