My laptop wouldn't believe the battery was new until I reset the SMC as well ( http://support.apple.com/kb/HT3964 ).
Perfect! I didn't want to wait for the Tri-wing screwdriver to ship, so I gave it a try by wedging a FH 1 in between two of the wings. It worked well to unscrew, but you must be very careful when resetting the screws that hold the battery. If you get them started with your finger (a little pressure with your thumb pushing straight down will get the job done) then you can do a few final turns with the FH 1. If you try to start resetting the screws with the off-center-FH1-workaround, you will strip the screw! Keep the screws centered and don't force anything.
My local Apple Store wants $179 plus tax to change this battery, AND I have to leave my laptop for "a couple of days." This is one store that clearly doesn't get it (Cherry Creak Mall, Denver). Thus, a DIY fix is mandatory... but, they won't sell just the battery.
iFixit sells the battery you need for $119 (http://www.ifixit.com/MacBook-Parts/MacB...), and once you get it, doing the replacement shouldn't take more than 30 minutes, even if you've never done a repair like this before.
