I've recently replaced the battery on my late-2008 MBP. Currently running it down to flat, and so far it's headed for a battery life of approximately 2 hours.

I've used the Battery Health app to determine the state of the old battery, and it's saying that currently the system is drawing about 25-27W from the battery. This is for a 15" 2.53GHz running on its integrated GPU, with display and keyboard on about 40% brightness, and wifi on.

Does that sound OK, or is something amiss?
