i understand that battery health fluctuates over time or is not at 100%. my battery health is 91% with 104 cycles with 7775 for max capacity. my capacity was never near the 8400 design capacity. i just hope it stays near 90% for a while. at 80% the battery is replaced and i hope that is years from now not months.

coconutBattery has had a history of being inaccurate, particularly with the Age of your Mac reading. Also, it's based on when it was made, not the date of purchase.

mine started out like yours at about 95% health and has continued to drop.

You can get most of this battery information by doing a system report/Power under "about my Mac" instead of installing another program...

2.6/16/256 rMBP, my "current capacity has now moved UP to 8577 from the lower one above, design capacity still shows 8460. Odd, several different battery status monitoring apps show the same thing.

Mine's been going up and down between 8400 and 8700 and now seems to have sort of settled at 8500. We'll see where it goes from here.

in a less than 1 year old macbook at what % battery health should you worry, 80% or a higher percent? i would hope that battery would decrease 5% a year not 10% in less than a year.

i did. it is very useful information. my concern is my battery capacity is 7800 and its not going up. it goes from 90% to 94% never more. i dont think even brand new was 100%.

the threads on here where people post there coconut battery generally are near 100% on newer machines or are older and have poor health. are there any other people like me with low 90s. by reviewing alot of posts it seems to me like a large portion have very healthy batteries. is this by chances?

It's not uncommon for a battery to be less than 100%, even when new. You really don't have anything to worry about unless the health drops below 80% before 1000 cycles. Apple usually won't even look at it until it's below 80%. Your battery sounds fine.

Be careful about getting info from batteryuniversity.com or other non-Apple sites, as much of the information there is generic and doesn't apply directly to the battery technology employed by Apple. A better source for battery information is Apple, since they know exactly how their batteries should be treated.
