I downloaded coconutBattery and the battery is definitely on it's last legs. 730 cycles, maximum charge 3230 mAh, original capacity 5450 mAh. I get about 30-40 minutes before the laptop just shuts down, no warning.
I ordered the iFixIt battery and required tools, it should be here by the end of the week. If it dies prematurely, I'll have Apple replace it. The bottom cover on the laptop is in great condition. Overall, the laptop is in great condition except for the battery an occasion click from the hard drive.
I also ordered a SSD, 8GB RAM and a Data Doubler from OWC, that stuff should be here by the end of the week too. I have a bare 1TB drive sitting around that I can drop in place of the current drive while I have the laptop open.
By the end of the week I should have pretty good running machine for about $300, not too shabby!
