    I've had my mbp for about 2 months and running istat menus.

    it thinks the battery is 95% health and 6500mAh capacity.

    is this normal? seems a bit too fast for me.

    Done 42 cycles

    If the degrading continues to less than 80% health in under 1000 cycles, you can get a replacement from Apple. Until then, there is nothing much you can do, but watch (or not, as it creates more psychological problems) the health and properly use the battery.

    I had 91% health at 30 to 40 cycles, now I have 130 cycles and have 98/9 % health. Therefore, and from any of the other thousands of threads, I conclude, that the reporting of battery health is not always 100% accurate and creates a lot of confusion.

    Thanks, on light web browsing I think I generally get around 6 hours. Never come close to the 8-9 hours

    Not all true... I have had an Early 2008 MBP, which I had the battery changed in after a few weeks because of some fault with it. The new one I got started getting really bad last year. Now I only get around 1-1.5 hours of web surfing with lowest light on screen.
    Called Applecare-which I have got, and told them: health at 46% and Condition: Replace NOW! , and they would not give me a new battery on the applecare, because it was just past 300 cycles (308....)
    That they would not change this tiny thing, which I payed about 400 dollars (2400 danish kr.) for in insurance, made me never wanna get applecare again. ****ing ************ - pardon my french.
