My HP 8510w has an 8-cell battery that gets about 5 hours of battery life. Then I have an HP travel battery that is also an 8-cell adding another 5 hours. Using just XP's Portable power setting and dimming the screen does actually get me 8-9 hours. With wireless and Bluetooth turned off, I get 9-10.
