    Hi all,

    I have a 13" MBP. (I think that information is irrelevant.) I have always wondered if it is bad for the battery to use the wall charger when the battery is fully charged. Does the battery lose its capacity to hold a charge? I had that happen with a cell phone I had awhile back. I left it plugged in all night, every night and it stopped holding a charge at all.

    It should not be a problem. I do that. I only have 21 cycles on my month-old MBP and the health is at 99%. Just remember to calibrate it every month. Also, do some research on MRoogle. This has been discussed countless times. Have fun with your new Mac!;):):apple:
