    Hello, my macbook pro late 2011 13" charging stucks at 99% for almost an hour. What should i do ? Is there is a problem with charger or battery or should i replace one of them.
    Thanks in advance

    Also there is a notification for Service Battery

    You need to replace the battery if you are getting the service battery messages.

    However, by design the laptop will not always charge to 100%. It is normal for it to stop charging a few % short.

    You can check this page to see the expected battery life for a MacBook.

    This does NOT mean you batteries are guaranteed to last this long. These are just estimates.

    I thought your power management chip would cap off charging just below the maximum battery capacity to protect the Lithium chemistry inside the battery cells?

    If you don't already have "Coconut Battery" -- download it and post your results here.
    I've noticed that when charging my older MBPro, it "stays at 99%" for a while.
    I just let it be and don't worry about it.
    The battery is older, it's down around 80% or so of its "original capacity" -- but it still works.
