Q: Battery life expectancy

My 2011 MBP shows green on the charging cable indicator light, but will not read past 99% on the screen. Is this a battery that is becoming worn and in need of replacement. And how could it be replaced?

MacBook Pro, OS X Yosemite (10.10.1), early 2011- 4GB DDR - 2.3 GHz I5
