Try using [Coconut Battery|http://www.coconut-flavour.com/coconutbattery> to see the capacity of your battery that remains.
Lastly, it's possible your computer is overheating for some reason, as your symptoms seem to point to that as well.Macbook 2GHz Intel Core Duo, iMac 2.66GHz Intel Core 2 Duo, Mac OS X (10.6.4)

When you note that Safari is using 112% CPU, what are you doing at that time? Is Safari being unresponsive? Does doing the same thing in a different browser, like Chrome or Firefox, produce the same problem? You usually only see numbers that high with stuck processes or really processor-heavy applications--not Safari.Aluminum Unibody MacBook, Mac OS X (10.5.8)
Currently Being ModeratedAug 26, 2010 12:41 PM (in response to shelcastillo)I'm having the exact same problem. I'll just be on a website and it will turn off automatically. It then will not restart unless I plug it in. It normally does it after using the computer for about half an hour. I noticed the problem first started happening at about 50% capacity, but it keeps getting higher. No it is at about 90-95% capacity when it shuts off. Here is my battery information-
Charge remaining (mAh): 2917
Fully charged: Yes
Full charge capacity (mAh): 2926
Cycle count: 449
Battery Installed: Yes
Amperage (mA): -1061
Voltage (mV): 12183
Any advice will be helpful. Thanks.
Currently Being ModeratedAug 26, 2010 3:36 PM (in response to esmith147)Your full capacity is very low and your cycle count is very high. As batteries age and get used, they can start reporting incorrect information to the OS or become unable to handle high loads or rapid changes in power demands.
In short, time for a new battery.Aluminum Unibody MacBook, Mac OS X (10.5.8)
Currently Being ModeratedAug 26, 2010 8:04 PM (in response to shelcastillo)If I have additional applecare service will a new battery be covered? I've only had my computer for a little over a year, so the computers still under warranty/
Currently Being ModeratedAug 27, 2010 5:24 AM (in response to esmith147)Apple generally only warrants batteries up to about 300 cycles.
But here's a clue as to what might be going on: You say you've had the computer a little over a year, but you have 450 cycles on your battery. That adds up to more than one full discharge-recharge cycle every single day, which is remarkably high.
How are you using your MacBook that you have so many cycles in so short a time? Apple recommends using the MacBook plugged in whenever power is available--don't unplug when the battery hits 100%.

Currently Being ModeratedAug 27, 2010 7:00 PM (in response to shelcastillo)Are you sure this problem is battery related? Because I've been having similar issues and I have noticed some other posts from the last days that talk about their Mac shutting down unexpectedly, also in conjunction with safari freezing up.
The only thing that changed in the last couple of days is installing the security update 2010-005, seems coincidentally but none the less worth a further glance.Mac OS X (10.5.7)
