    I have bought a laptop battery yesterday for my laptop. Its a genuine Asus battery. As on the label its having 15v and 44wh. I have written a program in Linux which says the real capacity claimed by battery circuits.

    Now when I check it, its reporting 15V and 31Wh which is like wtf to me. Because lost 30% of watt hour there.

    If I pug in my old battery, which lasts for 1hr (deplition 48%), it clearly says that its 15V and 44wh. It has been running of 3 years.

    Please help me...
    What I have to do... How to claim warrenty.. I know those people will tell me to check if its working or not.. And not to relay on these softwares. But I wrote it, and I have the real confidence. Because I have a battery that says the real specs and I have confidence in kernel

    Files of kernel /sys/class/power_supply/BAT0/
    Check these files for battery status and info. Most of them need 10^-6 multiplication to get real value.

    Thanks in advance
