    I have an Early 2009 MacBook Pro. Coconut Battery states I am at 84% capacity, 46 months old and 718 cycles. My problem is that the battery condition keeps jumping around. One minute it will say Good, the next it is saying Replace Now, and the next is just saying Service Battery. It changes each time it comes out of sleep mode, shut down, or is restarted. I'm having to leave it plugged in because I can never get a true percentage and can't tell if it will shut down.

    I'm just looking for some reasoning behind the jumping, hopefully without taking it to a Genius bar or sending it in. I know I am going to eventually have to replace the battery, but I should have about 300 more cycles before I get to that point.

    The reason is going to be that you're nearing time for a replacement. What "should" doesn't really matter. Individual units can require replacement prior to the averages or even beyond the averages.
