    Are these numbers right? I just powered it on few minutes ago , shouldn't the battery be at 100% health not 99%?

    1% really isn't a problem. Mine fluctuates between 98 and 100 depending on the day of the week.

    It's software, it isn't going to be 100% accurate so don't worry about it!

    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.

    Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug any time you need to, regardless of the charged percentage, and you never need to completely drain your battery. Just make sure you don't run on AC power exclusively, as your battery needs to be used regularly to stay healthy. 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.
