    I've just downloaded coconut battery and I have heard it wasn't always accurate, but just checked it and found this (see image). I've only had my mac around 3 weeks and i noticed the total capacity has already fallen to 99%. Is this normal??

    Yep, it fluctuates with the charge remaining, ambient temperature, etc.

    It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
