HT201842 Mac Book Pro Battery

What does it mean when there is an "X" where battery percentage usually is?

An X on the battery icon means the computer does not recognize that there is a battery installed. This is a signal that the battery is completely dead and you need a new battery. If your MBP is a model where the battery can be removed easily, you should take it out immediately. A dead battery can cause other damage if it swells up or leaks.

Replacing Mac Book Pro battery

I need to replace my battery for my original Mac Book Pro. Is there a specific battery I need to look for? Or do I just need a 15" Mac Book Pro battery? Do the older Mac Book Pro's run with a different battery than newer models?
Thanks for your help.

You're making this into more than it is. Tell him to get you a battery for your MacBook Pro. There's only one kind you can buy, which is the one I linked to.{quote}
Sometimes the simple link doesn't really answer the question. Thanks for clarifying that there's only one kind you can buy...and that's all I needed to know! When you said I couldn't use my girlfriends newer Mac Book Pro you more or less implied that there is a difference...but since you just said you can only buy one kind of replacement battery...that answered my concern. Thank you

Mac book pro battery only reports 3000mAh on battery.

My works 15" mac book pro says battery capacity is 3300mAh. I've tried calibration of the battery. I turned off power saving and left it switched on to run down battery but laptop won't power on again when the battery goes flat even when connected to the mains until its been charging for about 10 minutes at which point it says its got 1000mAh (1/3 charged). I'm sure it used to power on immediately from flat if on mains power.
The laptop is about 2 1/2 years old and currently my main use is at home connected to power but occasionally I need to use it on battery when it lasts less than an hour. I do have an apple care pack for it (not registered it yet! I know, its just been one of those things I've never got round to doing).
Can anyone suggest what I do next?

How long does a mac book pro battery last?

Just want to know how long a MacBook Pro battery is supposed to last as in, what is the useful life expectancy?

MacBook Pros have used different battery technology since their introduction 5 years ago. Even screen size can affect battery life. Of course the big hitter is usage patterns, so what I get may be completely different from what you see.
The main factor is battery life is cycles count. YOU must be using the MBP on battery power a little every day even if you use it as a desktop machine. The battery must be used regularly of it will die an early death.
You should be doing 1-2 cycles a week. The concept of cycles is explained here:
http://www.apple.com/batteries/
Apple says a battery should retain 80 percent of it health (not charge) after 300 cycles. The batteries in my Late 2007 MBP have not been so gracious. The first one lasted 11 moths before leaking out at about 45 cycles; the second plummeted to only 50 percent health at 15 months and 60 cycles. Hopefully the newer models do better.
Probably the best explanation for battery life and health is this User-contributed tip:

Mac book pro battery replacement

I have 13in mac pro and need a new battery. Which are the best? Do I have to use one from apple. Where to purchase one?

My brand new mac book pro battery won't charge to 100% it only charges to 99%. What's wrong with it ad how do I fix it?

My new MacBook pro won't charge to 100% battery it will only charge to 99%. Please help!

Nothing is wrong, that is normal. If you let it drop below 93%, it will recharge back to 100%. It is a feature to prolong the life of the battery.

Mac Book Pro Battery after 1 year...

Bought my Mac last year in march - used it sparingly then, and the long haul the battery would last for five hours.
Now, I use it for almost every class I'm in, sometimes with the charger, sometimes without - and it only lasts for maybe a half hour before completely shutting off at about 50% battery. I can't get it to restart until I put it on the charger.
I've had to download AdobeCS3, SecondLife, and one MMORPG. Are any of these effecting it? I've tried all I can think of to conserve battery power (minimal tasks running at the same time, lower display settings, etc) but it still blitzes out like crazy.
What can I do to fix this battery, or should I start setting aside money for a new battery now?

The Battery needs replacing. It is under warranty for one year. If you didn't purchase Apple Care to extend your warranty for another 2 years (including free battery upgrades) then you will need to pay for a new one.
You can check your battery statistics to see how many recharge cycles it has counted -- more than likely you are at 300 or more...time for a new battery.
One other thing you can do is to do a complete power reset, and see if that restores your battery functioning properly. See the MBP support page for instructions on how to do a complete reset (which is different from just powering down and powering up)

Mac Book Pro Battery Not Charging

I have a 2.2 Ghz 17' MBP running snow leopard. My battery is refusing to charge. While on standby power the battery seems to charge to 100%. but when in use appears to discharge quickly even with the mag safe attached. Mag safe lights show green then orange as the battery discharges and the battery icon shows the mains connector and the words (not charging) next to it. The icon rollover shows "Battery is not charging. Power Source : Power adapter". The battery info in profiler is below.

Mac book pro battery

i have a 13" which is closing in on being a year old. about 3 weeks ago, i noticed that the run time on a full charge was diminished greatly. i will get about 21/4 hrs on a full charge. the only change tot he machine is the installation of a larger(500g@7200rpm) hard drive, 8 months ago. is anyone aware of a similar problem or is this typical?

Hi hotrod 45: Check out the Apple article to see if any of those issues apply.

I have a issue with my mac book pro. For some reason it won't stay powered on. I can't get past the apple loading logo. The battery is fully charged so it is not the problem. Can anyone tell me what the problem may be and how can i get it resolved?

What happens when you use the MagSafe?

Hello, I have a problem with my mac book pro after running the battery dead on a game. The display has shrunk leaving two black margins on either side. What to do ?

Go to System Preferences>Displays and set the resolution to "Best for this computer" (or something to that effect).
