There are many guides on the net how to maintain the battery of your laptop. Anyway, the purpose of this post is to give real data as a reference for the GRT815M model.
I use my desktop replacement always running on "AC_Power". From time to time I perform some "exercises" of the battery (twice a month) by fully discharging the battery. So this is the situation after 3 years and 4 months:The "Charge Cycles" counts are not accurate. They are at least double since I have used the computer several times on battery, anyway. The first sign of degradation appeared on the third year. On another laptop (HP) and the same scheme for the battery exercises the battery is already showing degradation after 6 months...
I have to admit that the GRT815M seems to take special care in this particular situation. The HP computer charges automatically the battery every now and then when it is below some threshold, while I have never seen the GRT to charge the battery during the 2 weeks period between the exercises - this is almost equal to keep the battery outside the computer.

As concerns the usage of the computer:
It is always plugged in the power outlet. I turn it on only when I use it - usually every evening for about 6 hours. If I check the time counter of the HDD it says 7986 hours which is close to 333 days constantly working but this doesn't reflect significantly the battery maintenance since the battery is charged even if your laptop is off but still plugged.

Hi i pretty much just leave my laptop plugged in, with a few monthly cycles. it concerns me at the fact that it states the design capacity is 59.2 Wh, but the actual capacity is 44Wh! How did you check how long the hard drive has been runnin for, thats pretty neat
Well 44Wh seems not that bad for 4 years old battery...
One way to check the S.M.A.R.T. attributes of your HDD is using a simple toll like this here:

It runs in "Command Prompt" and there is a line in the output that says: "Power On Hours Count". Here is an example output:
