    I just bought this Friday, but noticed yesterday and today battery stays at 99%. It's only ran off battery a few hours Friday. Should I be concerned or is this normal?

    All my other apple products go to 100%.

    The full charge will be anywhere from 94% to 100%, the battery controller trickle charges and trickle discharges the battery to get it's juices flowing.

    If it bothers you, unplug it, let it run down to about 90% and plug it back in, it'll go right back up to 100%.

    Cool thanks, just double checking things because I declined extra warrantees because I planed on changing ram, drive and optical drive so figured most would be voided.

    RAM and HDD/SSD are user upgradeable and do not void the warranty. Replacing the optical drive with an optibay adapter does though, but if you have to give the Mac to Apple for repair, you could always put the ODD back into the optibay.

    RAM and hard drives are deemed user replaceable and would not void your warranty.

    The optical drive is another matter entirely...

    Its fine. It does that sometimes.
    It shouldnt go under 80% charge by 1000 cycles though.

    All Macs come with a 1 year hardware warranty - FYI
