Can anyone tell me how long it takes to get a new battery charged? I see they tell you how to calibrate a battery but I don't see anything that says you need to charge the battery immediately, before you use it for first time, and approx how long it takes. Just says it changes color when charged.

Change it to percentage so you know when it reaches 100%.

I would advise against calibrating it the first time you use it because, I believe, it already comes calibrated. I'd give it three to four weeks then do that process. As Benny stated, you can change the battery icon's view from bar to percentage.

I think she was referring to the magsafe light on the charging connector which turns from orange to green when it's fully charged. It takes a couple of hours to fully charge it. It should be partially charged when you buy it, though.

The green light did come on after about two hours. I decided to take it to the Apple Store to download lion. The tech also helped me back up my phone and download software through 4.3.5. Living near an Apple Store comes in handy!

I apologize in advance if I'm asking a dumb question, but I just can't help myself! I am very detail-oriented and have to try to get everything right. Now PLEASE don't make fun of me cause y'all know I tend to be very sensitive. I was charging my MacBook Pro for the second time when I guess it was close to finishing and I had to turn it off right away. This time it was taking longer to charge since I was checking things out to familiarize myself with it. Macs are great but I'm really a newbie and afraid I'll make a mistake and break my computer. Not really. I just am lazy and hate to have to go back to find out what I did wrong and then figure out how to fix it. Anyway, after 2.25 hours it still wasn't fully charged. Now my question: Is it better to (1) plug it in later to finish a full charge before I use it again; (2) just start using it and not worry that it wasn't quite fully charged; or (3) have a glass of wine and take a nap?

Again, my apologies, especially to Naps, who I'm sure would like to strangle me right now :(.

You don't need to worry about overcharging or damaging the battery. You can keep it plugged in after it's done charging and it won't hurt it. I keep mine plugged in 24/7. The only time I unhook it from the power supply is when I'm taking the MacBook into another room or out of the house.

I just thought that the first couple times when the battery is new you should drain it completely and then charge it to 100%. Is this battery different from that of the iPhone?

I get the impression that you want me to stop talking about my new MacBook Pro as I have exhausted the subject and enough is enough! You blocked one of my threads.
I think the issue Naps had wasn't that he wanted you to stop talking about it, but that you created redundant threads in which to discuss it.

I'm not sure about the first couple of times but it's recommended that you drain the battery completely every month or so. The same practice applies to both MacBooks and iPhones. I'm pretty good about this with my iPhone but not so good with my MBP which I leave plugged in all the time.

Keep in mind if you plug it in to charge and the battery is not lower than 95% it will not charge. This is to keep it from overworking the battery, extending it's life. That used to get to me when I got my first macbook but now I am glad that it works that way. If you want to see it get to 100% make sure it is below 95% and then charge it. I used to do this all the time. Now, never, unless I am heading out and I won't every last drop of juice in the battery.

But like Europa I never unplug it unless I am taking it with me. Of course mine is going with me quite a bit--even if around the house or out to the patio.

Thanks friends for your advice and especially reassurance. As I said in I believe my last post what you said about too many threads, not messages, makes sense. Now I understand and it makes perfect sense. I do get it! It won't happen again now that Naps and you all pointed this out. I hope not! I will drain the battery once a month. I am glad that the mac has built-in protection from overcharging. The iPhone does not, correct? Now it's time to move on! :)

You can't overcharge the iPhone battery, either.

Then why all the warnings (not from Apple) to not leave the cord in for longer than 12 hours?
Believe me - you can't overcharge your iPhone's battery. I've left the cord in for longer than that and had absolutely no problems. You notice that the warnings are not from Apple. There's a lot of conjecture and misinformation on this subject.
