The 2.4 Ghz Unibody Macbook gets 2:40 at half screen brightness, word processing, and web browsing. MiniBatteryLogger helps keep track.

The recharge to 70% capacity while on and running at 100% screen brightness and some video will be 2:00

The recharge to from 70%-100% is at a slower rate than 0%-70% with the remaining time being around 1:15

Total charge time while on and running web browser, perhaps some streaming video is 3:15
Total charge time has been timed at 4:00 (probably with video).

The off brand batteries are around 2:00.

The battery can be drained in an hour and half. (Looks like the normal battery, but I'm not positive)
