Maintaining the Battery

[NotFound]

Ok, so I have calibrated the battery. And I'm sitting here with the MagSafe in and it says on OS X that it is running off of AC, but does this still go through the battery?

I guess what I am saying is- is it harmful to my battery to keep the magsafe in while the battery is fully charged if I am just sitting at my desk?

No.

No it isn't harmful or no I shouldn't have it plugged in?

It's not harmful. It doesn't really matter. Either way.

I'm pretty sure that it bypasses the battery, just getting its energy straight from the electrical socket (like a desktop). I might be (read: probably am) wrong though.

I used my old iBook almost exclusively on mains power every day for 3 years. When I sold it recently it still had 93% of the battery capacity, so no problems there. BTW, I re-calibrated the battery every couple of months.
