    I have a 2006 Macbook Pro (Core Duo) with horrible battery life. Apple sent me a replacement battery about a year ago, but now this one is acting up, also. I'm getting the "Service Battery" indicator, so I've tried recalibrating several times. The problem is, there's still nearly half a charge on the battery once it says it's empty. It takes well over twenty four hours for the battery to completely deplete after going into sleep mode. I want to reclaim that battery capacity. How do I do this?

    Generally you can't reclaim capacity. Your best bet would be to buy a new battery.
