The battery only supplies power when the engine isn't running. While the engine is running, the battery is actually a load, and it is the alternator that powers everything. If you increase the electrical load, then the alternator has to work harder, and so it saps more torque from the engine.

The alternator doesn't put out "extra" power either -- if only all the hydrogen generator proponents knew this...
