ok, i've had my Black Macbook for abouot 3 and a half months now. it spends about 80% of its like attached to power. i dont turn it off much. just leave it sleeping while its connected to power and im not using it. it has gone through 29 charge cycles.... and is currently sitting on 93% battery health!?!?! that cant be good? :(
any tips? or is this normal?
 
Unplug it from the power and use the battery more, or drain the battery to 50 % and take it out of the laptop. I've gone thru 202 cycles and my battery is now at 86% health.
I always discharge my battery completely before plugging it into normal power again.
 
Apply any battery updates and recalibrate the battery.

Run it all the way down until you get the low battery warnings (second one iirc) then fully recharge.

To calibrate the battery:

  1. Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
  2. Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
  3. Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
  4. Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
  5. Turn off the computer or allow it to sleep for five hours or longer.
  6. Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.
Repeat the calibration process every two months or so to keep the battery fully functioning. If you use your MacBook or MacBook Pro infrequently, it’s best to recalibrate the battery at least once a month.

If you purchased additional batteries, repeat the calibration process with those batteries as well.

I also had the q and I phoned Digicape and spoke to one of the techies. They told me the batt will run down to about +-85% health and then do a full charge up to 100% health. I found that this was true and now I dont worry about the batt.

But always good practice is to run the batt low at least onces every few days and then charge it up again.
 
Mine has done 70 cycles, and on 95% health ... pretty much run it down completely when it is not connected to the AC ... If I have to unplug the AC mid-charge, I will keep it disconnected until it is completely run down again.
 
I dont want to put a kibosh on it so I'll just say I'm pretty happy about my battery health so far. ;)
 
You must also look on the Apple site to see if your batt maybe fall under a bad batch. They will have sn and model numbers.
