Macbook Pro Battery Problem

[Casey01]

So when I bought this the guy said that Apple installed a new battery on it recently. I believe him because when I downloaded the iStat Pro widget it said only 2 or 3 cycles which is because I calibrated the battery. But I just finished charging and the light is green. But it says the charge is only at 97%. I don't see why it should be like this.

Also when it's not plugged in the battery only lasts maybe 3 and half hours from just surfing on the internet. But I thought it was supposed to last like 6?(I'm thinking that since mine is an older model, that could be it. Please help.

Take it with a grain of salt. anywhere from 95-100 is fine.

As far as the battery lasting time... Check your activity monitor, and screen brightness.
