I am going from a Dell Laptop I had for 2 years to a new Macbook. My battery on my Dell stopped working only after 1 year. I hardly used the battery as I had my laptop plugged into an outlet. I am wondering if I overcharged the battery and thats why it stopped working. My question is, is it possible to overcharge the battery in a Macbook? Would it be wise to use the battery until it dies and then just recharge it and just use the Macbook plugged in at that time when it's recharging the battery? Thanks
