Is it too late for me now?Yesterday I replaced a battery, which had 1433 cycles since 11/2008 and was down to 47 % of its original capacity.
The batteries built into the current MacBooks are quite good and are promised to keep their capacity over 80% for at least 1000 cycles.
But how come, you have 462 cycles in less than a year? That is almost two cycles per day. You don't need to disconnect the Mac from the power once it has fully charged.
This should answer most, if not all, of your battery questions:
Apple Notebook Battery FAQ by GGJstudios
The F.A.Q. includes the following topics:
- BATTERY INFORMATION

- AC POWER
- BATTERY LIFESPAN
- CHECKING STATUS AND HEALTH
- WHAT IS A CYCLE?
- BATTERIES ARE NOT COVERED
- BULGING OR SWELLING BATTERY
I have 88% with 771 load cycles on my 2009 MBP, it is on 10 hours a day and I am really careless about charging it. No idea how you managed to do 450 load cycles in such a short timeSorry for my horrible english grammar but english is my second language. I have early 15" macbook pro, and I bought late December 2011.Right now my battery cycles is 462 therefore my current max is 85%, 5922 mAh. Is this bad?
No. Have you read the FAQ yet? And again, do you charge the MacBook Pro and then after that has finished use it on battery again? Otherwise I can't explain the high cycle count.To take care of it?
get iStat or Coconut batteryHi!
How can you check how many cycles you battery have done?
*just needed to look for it...
The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries in older Apple notebooks.PS: If you're worried about battery health, first thing to do is calibrate your battery, to check that the health being reported is accurate.
