    On my new MBP 13 (well, 2 months new), there are 15 cycles on it (i keep it plugged in a lot). However, coconut battery says i have 5391/5450 mA, 98% battery health. Is that normal?

    Hi, mine is at 94% after only three cycles. I think the health indicator is just a rough estimate, so you should not worry about the last digit too much ...

    Mines at 93%. I'd love 98%. I don't think you have anything to worry about, me on the other hand.....

    It might just be an inaccurate reading. Try to calibrate the battery.

    I have almost 200 cycles on it and it is still at 100% battery life because I calibrate every month.

    i've noticed that the battery health can fluctuate between 90% - 100%, whilst not being entirely truthful. anything in this range is still considered good, and you have nothing to worry about. :)

    Funny, mine was at 98-99% before I calibrated it. 5 cycles.

    Battery can fluctuate up to 10%, even when calibrated. Don't be concerned unless your health consistently stays below 80%.
