    For me, the 6 cell in the t500 with the base screen can last about 4 hours with simple use like word or internet.

    Right now, the battery meter is saying that I have a little over an hour left at 44%. This is for the six cell on the T500 with the ATI card at maximum performance.

    The biggest factor in battery life is screen brightness.

    i have a T500, wsxga+ with 9 cell, 4GB RAM and 4GB SDHC readboost.

    6:30 hours-7 if you activate battery stretch, turn the LCD all the way down to 10-20%, wifi off, BT off and integrated graphics. i usually browse over the ethernet, read and stuff.

    in high performance with discrete graphics, max sound and gaming, it lasts upto 2:30-3 hours at max.

    watching movies with decent brightness (60) on integrated graphics, it lasted max of 3 movies(approx 4:30 hours)

    Where can I reorder a 9 cell? cause right now i set everything to long battery life, intergrated, and power saver mode and its telling me I have about 4 50. I thought there was a 7 hour battery life on these or is it because I have 6 cell?

    6 cell is better than 9 cell in lower weight and fits perfectly. 5 hours is very good for any 15.4. the max i manged out of the 9 cell and T500 is about 6:47.

    i dont like the extra weight and the battery protruding outwards.

    Anyone know how long the T500 runs with a 6 cell + Ultrabay Battery II?

    Actually, since the Ultrabay battery II is 3 cell, would this combination with the 6 cell be equivalent to the 9 cell battery?

    Theoretically, yes, but note that the UltraBay battery is completely discharged before the 6-cell main battery is used, which is hard on the battery and can cause rapid degradation of the UltraBay battery.

    Awhile back Mark_Lenovo @ the lenovo forums posted a poll if that would be a feature people would be interested in. Needless to say, there was hug interest. Haven't heard anything from that...been almost a year I think.

    That's a shame. I don't think it would even be that difficult to implement. If only the actual coders would read the threads sometime.
