Help! MacBook Pro (Mountain Lion 10.8.2) battery percentage instantly dropped from 100% to 88% right after disconnecting the charger.

Help! I just realized that my MacBook Pro running on Mountain Lion 10.8.2 battery percentage instantly dropped from 100% to 88% right after disconnecting the charger. It's been 333 cycles, age 25months, and 88% battery health. Is it normal for the percentage to drop all the way down to 88 just right after unpluging the charger?

 

Thanks.
