    Mine has 663 for 2yrs 11mths old. Can't really draw any conclusion on what is "normal"....

    I have a mid 2010. It has 270 cycles on the battery. Obviously I keep it plugged in almost all the time.

    You do realise that you can get a new battery? The state of your battery has nothing to do with how long your machine can last. Usually, you'd want to change battery when you get to around 1000 cycles on a mac laptop.

    You can also consider replacing the battery when you no longer get reasonable time on one charge - my opinion (for what it's worth), less than 2 hours on battery. The cycle count is meaningless at that point.

    I just stumbled across an app the other day called Battery Diag (via the Mac App Store). It's free and actually fairly handy for checking your battery health out. It'll give you a % of what your battery capacity is now compared to it's original capacity.

    Age wise that is about normal, before I needed a battery replacement for a 2010 it was closer to 700 cycles until two cells died and it displayed half the cycles.

    Keep in mind battery health matters more than cycles, after 4yrs most batteries rapidly decline in capacity and OS X on unibodies will nag you with a "battery replacement warning" around 74% capacity status.

    thanks. I was still on 2.8 ( which has a 'cleaner' layout)

    Cycle counts are completely random, I had a battery replaced with only 270 cycles on it. With Lithium Ion batteries it's actually best to never let your charge get under 50% before recharging.
