    Anyone know why my battery(MBP 13 2010) is dead within 3-4 days even though it is turned off. i have unplugged battery from logic board and it held charge so maybe its shorting when connected to logic board

    i bought it with the problem so im thinking maybe it had a water spillage or something.

    runs fine on mains, however it doesnt run smooth on battery, gives a maxed out cpu usage and high kernel task of about 160.

    other than that it runs fine on mains, its a second computer for me and one i use at work for nights etc so i dont use it unplugged therefore causing me no problems.

    Any help would be much appreciated

    Seems to be a bit fast if it's turned off. Get a replacement.
