Problems with MBP Battery

[thousandisland]

Hello people,

Issue occurred when I charged my MBP (uni-body, 2nd latest gen) and it was 100%. I plugged out the cable not wanting to damage my battery and the moment I did so, the MBP "crashed" and shut down for the first time in 10months.

I had to power it up again and when it was loaded, the date/time was resetted to 2001.

Weird thing is the, battery condition now is 'Condition: Replace now'

I checked my coconut battery and statistics (full charge capacity) for my battery is still healthy. From system preferences,
