So my Lithium-ion battery on my last two iBooks gave out after 13 months. I figure I'm doing something wrong.
I have used the laptop often plugged in, is that the problem?
I bought a new battery recently and I want to make it last longer. My question is: Is it okay to put the dead battery in while I have it plugged in at home and switch the batteries out with the good one when I'm going to use it away from the outlet?
