    Hi,

    I've just downloaded Centrino Hardware Control 1.8.2 just to monitor temperatures mainly and I've just read on the Battery tab that my battery has a wear rate of 8%, this means that when it's fully charged, it's actually at 92%!!!! I'm astounded for this finding since my laptop is BRAND NEW!!! I know it should downgrade because of the use but this is computer is a little more than a week old. Is this really accurate?? Is it normal to receive a battery with this fault? The first time it was turned on was last Monday (12th).

    I have an i9300 w/following specs:
    Pentium M 1.73Ghz
    1 GB Ram
    60GB HDD
    8x DVD/CD burner
    256Mb Nvidia Geforce Go 6800
    9 cell battery

    $1289 w/out shipping and taxes

    Drain the battery down to around 1% and then recharge fully, then see what the reading is after.

    That happens sometimes...especially if you leave your lappy plugged in all the time. I have seen this with many laptops. There is a few threads on other sites about taking the battery out if you are leaving the laptop plugged in. They say this will prevent that from happening.

    Thanks, will definitely try to leave it down to 1%. I do exercise the battery, meaning that I work on battery most of the time and only plug it when it gives the low battery warning. Will let you know what the reading is afterwards, I hope it was just a misread...

    I had 6% in a month and 99% of the time I have my battery out. It is still 6% after 4 months. Friend of mine with dell 9300 has 17% in a year. But he has battery always plugged in. So yes it is a bad thing to see.

    I think it may be in tolerance borders. See if it is getting worse in a month. Also when the battery is brand new, it needs few cycles of emptying and charging in order to get max perfomance. If it stays around 8%, maybe it is good as it can be.

    I don't have 9cell batt, but that should be an advantage. I think mine is 6cell.

    So would anybody else care to post their wear rates?? I'm just curious to see what would the average be on a new laptop.
