Hi All,

 

I know there are lots of other articles out there about the topic I'd like to ask. But none of them gave me a sufficient answer.

However, my McBook Pro (beginning 2009 model) suffer on considerable battery waekness. The battery it self has a health status of 87% and so far worked even under mountain lion pretty good. Hence the combination of Mountain Lion and a mac book pro isn't always the cause for struggle.

 

Accodring to the activity display there's nothing remarkable. The battery drain do not depend on the browser I'm using as some others reported here.

 

It's only some days ago since my battery drains much much faster than before.

 

Is it possible the battery itself is somehow damaged and must be replaced? (with the given facts above?)

 

Maybe it's pretty hard to get a spare part here in Germany, since the battery is build in.

 

Any hints to this weird problem?

 

Thanks,

Michael


MacBook Pro, OS X Mountain Lion (10.8.2), OS X snow leopard also

    Go to SYSTEM PROFILER>HARDWARE>POWER>BATTERY INFORMATION and post this from your MBP so that it can be evaluated.

    You have had your battery for almost four years and that often is time to replace a battery.  The 712 cycles do indicate that it is getting old, but with the condition stating Good (Gut) is in its favor.  A battery should be replaced when the health level drops to 80% and you are not quite there yet.

     

    I notice that your battery has been run down to 574 mAH.  That is quite low.  If you can, keep it connected to a wall outlet as much as possible. I do and about once per month I use it under battery power discharging it to about the 40% level.  That way you can maximize the battery life. 

     

    I suspect that based on what I can see, you may be able to get a half to full years use out of it, at best.  It would be most prudent to get a replacement at an Apple store.  There have been too many complaints about third party Mac batteries that don't last a month to make the low price cost effective.

     

    Look at this Apple support article that may assist in prolonging your batteries life:

    Hi,

     

    thanks for explaining. How did you reveal my battery is more than four years old? Just quite interested....

    Indeed it's more than four years old and tried always to drain it until my macbook switches off. Keep the macbook for one or two nights off with the completly dischargared battery was a nice concept in the past. But nowadays it seem's no longer working...

     

    I'll call a certified apple retail store tomorrow asking for a replacement and it's costs.

     

     

    Thanks,

    Michael

    January 2013 minus early 2009 = ~4 years.  The battery costs from the Apple website are as follows:

    For 2010-11 Macbooks. Macbooks Pros and Macbook Air there is a new firmware update that fixes a battery charging problem:

    http://www.macrumors.com/2013/01/30/apple-issues-smc-firmware-update-for-macbook -macbook-pro-and-macbook-air-models/

    "...addresses a rare issue on some Apple notebooks where a battery that has accumulated more than 1000 charge cycles may unexpectedly shut down or stop functioning."

     

    Install it via Software Update

     

    This won't fix dummbaddel's problem with a 2009 Macbook but others should try the update before replacing the battery. It solved my problem.
