It doesn't look that way. Maybe you use coconut Battery to check your battery health and report back.

Where can you get coconut battery, in the app store? That looks like a cool tool to have! Are there other similar apps or is this the best? Also, does iStat Pro give this info or is that just for temperatures? I just got my MacBook Pro and I'm looking to do the most to keep it healthy so it lasts as long has possible! Anything I can do to monitor things and to maximize battery health, I want to be sure I do!

Sorry, OP, didn't mean to hijack but seeing your coconut battery stats just brought up all these questions. :eek:
 
iStat Pro offers a lot more about your Mac in general (Wifi info, CPU usage, ram usage, etc.) But it does let you know how many cycles your battery has gone through and how healthy the battery is (it gives you a percentage).

iStat Pro, as mentioned before is much more thorough though, maybe you could even invest into iStat Menus, if you are the kind of person wanting to know what is happening on your Mac.
 
i just used istat pro and it says that the battery health is 85% do i need to change the battery?

Have you followed the guidelines set by the FAQ GGJstudios put together?

If you still have Apple Care you could ask for a replacement, as the battery you have should get to 1000 cycles while still retaining 80% of its capacity.
 
can you ever regain back or increase the design capacity of your battery? i could see mine increase and decrease everyday.

I do still have AppleCare. How should I approach it with the genius bar?

Bring in the Mac including the battery and let them test the battery and ask if they will replace it if it does not have more than 80% battery capacity after less than 1000 cycles.

Ok cool. Thanks for the heads up. Never seen the fine print about % before certain cycles.

It fluctuates regularly. My 2009 MBP went from 99% to 89% in a matter of weeks, then got back to 97% in the following months and then switched between 97% and 94% for quite some time. Now by battery health is reported as 99% after 250 cycles or so.
Read the FAQ I may have posted once or twice or thrice.
