I just got a new battery for my 13" white Macbook.  It is an Apple Battery.     I ran Coconut Battery and it tells me it has a design capacity of 5020 mAh but this has a capcity of 5486 mAh or 109%.


Is it ok?  I contacted the place I got it (for $20 less) and they said it was built above factory specs.  It is charging fine I just want to make sure.

    Yep it's fine. You may notice the capacity go up or down a few points after you calibrate it. You can do that whenever.

    Completly normal. I have a 1.5 year old MBP. Battery has 12 cycles on it as I only use it on battery once a month to keep the battery in good shape. After the 10th cycle, the battery went up to 102%. Now at 12 it's down to 101%.


    I also have a MB that has 197 cycles. Last time I used it on battery, the health jumped up to 99% but only lasted two hours. After charging, it went back down to 96%and lasted 4.5 hours which was normal.
