Looking to upgrade hard drive and ram NEED help

[bsmithphoto13]

I have a 2011 Macbook pro 13", Im running lion right now and am getting between 5 and 7 hours of battery life. I am looking to upgrade my ram and hard drive and am wondering if that will effect my battery life? I want to go from 4 gigs of ram to 8 and from the 320 gig hard drive to a 1tb 5400 rpm one.

ANY input would be appreciated!

RAM and hard drive will have little, if any, effect on battery life. There are other factors that impact battery life to a much greater degree. Read the BATTERY LIFE FROM A CHARGE section of the following link. This should answer most, if not all, of your battery questions:
