    I have noticed that lately, my MBP Mid-2009 battery isn't lasting as long on a single charge as it used to.

    So, I downloaded and ran coconutBattery (attached results)

    After 152 Charges - I'm getting 90% battery capacity. Is there a way I can improve on that. Or, is this number about right for the age of the MacBook Pro?

    Your battery is fine. Also, there are dozens and dozens of threads on this you can read, if you search the forums.

    Many thanks for your knowledgeable reply! :cool:

    Yes, I work on my MBP... a lot! And travel... a lot! It's a very heavily used computer.

    thats not a lot of cycles. My former 8 months old MacBook Air bought brand new had over 600 cycles when I sold it.

    Well, my MBP is almost 7 months old, has 149 cycles, and is still at 99%/100% capacity. If your battery is at 80% health with under 300 cycles, then I believe you can get it replaced by Apple.
