Answer 1

Hi JediZenMaster,
THe "charge remaining" figure simply tells you how charged up the computer is at the present moment (charge it , it will go up, use it on the battery, it will go down.)
The figure that tells you more about the health of your battery is the "maximum charge capacity". In your case it stands at roughly 90% of the original capacity, after the equivalent of 166 charge "cycles".
This is OK, but it sounds to me as if you are probably using the battery fairly heavily, charging up every day and then running right down again, to have run up 166 cycles since last August. THis isn't really the best way to treat Lithium batteries if it can be avoided.
You might find it worth reading neuroanatomists excellent battery FAQ at http://discussions.apple.com/thread.jspa?threadID=1764220 and Apple's own information about notebook batteries at http://www.apple.com/batteries/notebooks.html
(whoops, sorry for repeating you stedman - went off and had a cup of tea in the middle of writing the response and didn't know you had posted)
Cheers
