How long can a 11.1v battery last for?

I have a acer 5720 and wondering how long can this new replacement battery last for. I need it for school. More details here ( http://tinyurl.com/oyc26r8 ). This is the best buy for me. I'm replacing the battery because the one i have know can only last 5 minutes (it's probably broken)

    how long it lasts depends on what you are doing

    its not the 11.1v thats important

    its the 4400mAh

    if you get a 6000mah or higher battery it will last longer

  3. light usage--eg web browsing i would guess 2 to 3 hours

    depending how bright you have the screen etc
