Should I replace my 3-cell battery with a 9-cell, in my Acer Netbook?

    Just bought an Acer eMachines eM250-1162 Netbook at Walmart $228. I
    was disappointed to find that the 3-cell UM08A31 battery will only
    last 3 hours.

    It is my understanding that I can replace the 3-cell with a 6-cell, or
    a 9-cell, and get longer battery life. For example, this 9-cell
    battery:

    http://www.amazon.com/Extended-Capa...ref=sr_1_1?ie=UTF8&s=pc&qid=1264961797&sr=1-1

    Claims "Compatible Part Numbers: UM08A31"

    I suppose I also have to assume this will raise the profile of the
    netbook, quite a lot.

    The first customer review at that site says "this is a big battery. It
    extends out the back and off the bottom a good inch" so yes you will
    pay for that extended use time with much added weight and size.

    With my Eee PC netbook I went from a 4400 to a 6600 mAh battery
    without any change in the battery case size. That's because the 4400
    mAh battery had some empty cell holes inside the case and the
    replacement 6600mAh battery filled the empty holes with cells. That
    increased my use time from about 3 to 5 hours (surfing with wireless
    on). I think the extra time gained from a monster battery just isn't
    worth the pregnant look and added weight but YMMV...

    I have four 5200mah and one 10440mah batteries. I actually have a
    5200mah and a 10440mah with me right now out and about. I never ran out
    of power yet with carrying around two batteries. Although if I do, I
    guess I'll start carrying the other three around with me too. ;-)

    Why not return it and invest the extra cost in a netbook that comes with a
    factory standard battery having higher capacity?
