I just bought a MBP 13" yesterday. I talked to the guy at the store about the battery and how I'm supposed to "take care" of it. He said to run it down and then fully charge every time. However after searching the forums I read a lot of posts of people saying to always keep it fully charged (like the iPod Touch) or to let it run to 1/4 battery life and then fully charge it. Now I'm confused. What do you guys do? P.S. i'm sorry if this was already posted somewhere else. In my defense I did actually search battery life topics but the search wasnt working for me.
