It stops at 99% and lasts about 2 and a half hours of just regular internet reading (no special programs, videos, etc...). I am wondering if I have a defective battery and if it should last longer?
I can't speak for 3rd party batteries, which I would never trust or recommend, based on the number of problems people have reported with them. As for Apple batteries, it's perfectly normal for a battery to stop charging before 100%. Battery life from a charge is dependent on many things, including configuration and what you have running. How long a battery should last is based on how you take care of it. Details on these statements are found in the following link.

This should answer most, if not all, of your battery questions:

Read the BATTERY LIFE FROM A CHARGE section. There is no simple answer, since so many factors affect your individual battery life. That section will explain more fully.
