    My brother just bought a 12 cell of some website for his hp laptop. I was curious about this and so I installed batterybar on his computer, and it said the battery wear had less mWh then the capacity. I know that this is not going to make a lot of sense to explain it so I will provide approximate #'s of what batterybar said.

    Capacity: 110000 mwh of 110000 mwh
    Charge Rate 0mw
    battery: charged
    Full lifetime: calculating
    A/C: Connected
    Battery Wear: 0% of 88000mwh

    How can the battery wear be only 88000mwh when it says that it is rated for 110000mwh?
    Is my brother still able to access the full 110000mwh?

    Thanks!

    Thank you! That is probably the reason, as he has yet to use it.

    it still says 0% of so it means it's not even weared out a little no matter what number is after those "of" as it still 0%..

    Though to get correct readings, just calibrate the battery as said.

    What's the real capacity of the battery, the capacity the shop told you the battery will have?
    And what's the capacity of the same battery, just as an original HP part.

    It's possible that HP sells the battery with 88Wh, the shop replaced the worn out batteries with their own but newer batteries, which have 110Wh.

    You will use the full capacity of the battery. The 88Wh is only a fix number which a software can use to calculate the battery wear level if it compares this fix number with the calculated capacity.

    The important number is the capacity. This number gets calculated each time you charge and discharge your battery and should be equal to the capacity the shop labels the battery.

    Just discharge your battery and look what number changes and which number is constant.

    And calibrate your battery (full discharge and recharge) because the 110Wh just looks too uniform.
