Macbook Pro battery drains in 30 minutes, Help!

Hi,

I have a macbook pro 13 inch mid-2010. I realize the laptop is going on 8 years old but I can't seem to figure out why the system is draining my battery so quickly. It lasts upwards of 40 minutes on battery on a good day. Before settling on a new purchase to upgrade, I was hoping someone could help me get a little more life out of this bad boy.
