    Hi all.
    I been reading about this laptop, but I do not know if your battery is 44Wh or 40WH.
    The store says it has 4-cell 40WH, but reviews say it has 44wh.
    Some reviews say that the consumption of battery is very good and other is normal.
    How many hours does the battery last? (browsing, brightness at 60%)
    Thank you.

    Can you get a store to let you run the BatteryInfoView program? (Unlike HWiNFO it doesn't prompt a UAC warning on my computer). Then look at the designed capacity and full charged capacity values (ignore the wear value).

    I suspect that the answer is the 44WHr. I think the 40 Whr battery was phased out in mid 2012.

    Hi!
    Unfortunately, I can not run that program. It is an online store.
    The model is NP900X3C-A01ES, with windows 7 home premium 64. Is it old?
    Is there much difference between 40WH and 44Wh?
    Thank you.

    The mAh rating without the corresponding voltage means nothing. However, if we assume that the nominal voltage is 7.4V (two cells in series) then the nominal capacity is 46.6Whr which is consistent with an advertised 44Whr capacity. My NP900X3B has the older battery which is rated at 11.1V. So, by deduction, I think that specification indicates the newer battery with the higher capacity which will give about 10% more run time.
