I've tried searching for this answer, but not successful so far:
I had a Macbook 2007 with one of those replaceable batteries...which I never took off the charger. I treated it like a desktop and kept it plugged in. One day, the battery expanded...they said it was normal, but I was worried it was cause I left it plugged in all the time. Since now manufactures are learning towards non user replaceable batts...with the V, can anyone confirm if it's something that can be plugged in all the time? If so, does it wear the battery down?
