I have the 13" mbp and when im at home i like to leave my mbp in and use just my 20" monitor instead of the duel monitor. In order to do that i have to leave it plugged in and does anyone know if u can over charge these batteries?
 
You can leave it plugged it. When it's done charging, the magsafe will change from amber to green and run off AC power. Just remember if you're leaving it plugged in for a long time, calibrate the battery once a month.
 
^^^^

Agreed, leaving it plugged in is not really an issue
Just don't take the battery out! It reduces the processor speed

How do u calibrate the battery and what would that do?
 
a bit off topic but when the battery is fully charged can I unplug the magsafe after i shut down the macbook but then plug it back in before I turn on the macbook, i assume the magsafe would display a green light as it will not charge the battery as long as its above 95%. I don't want to keep it plugged in when not using the macbook.

I want to know the same thing.

People complain about MagSafe chargers overheating while remaining plugged in but let's say your computer is shut down or sleeping, there is very little to no power being supplied from the MagSafe so how would that be an issue?
 
u still cant over charge the battery even when ur running in boot camp with windows?
