I spoke to Apple Care (I took the 3 years) and they agreed to replace it under warranty.
#MAC BATTERY HEALTH VS BATTERY HEALTH 2 FULL#
It reported 1500mAh on full and 230 cycles. It is 2 years old and the battery was down to less than one hour of charge (sometimes only 20 mins). Apple also offers coverage on batteries within the scope of AppleCare's Protection Plan, again if the battery is considered failed/defective, not consumed.įor several of the above posters, your system profiler logs on your battery seem to be incredibly out of whack and I'd recommend either contacting Apple for some assistance or visiting your local Apple Store to have your battery checked out. I've seen 3 year old machines with 40 CCCs and 9 month old machines with 250.Īpple does offer coverage on batteries if the machine is within the one-year limited warranty and the battery is considered failed/defective, not consumed. So based on the frequency you use your machine (charging and discharging) your CCC will vary. A charge cycle occurs when the battery has depleted and then been recharged by 100%. CCC / Charge Cycle Count will start at 1 (on a brand new battery) and can go up from there. It's never a good idea to run the battery completely dead (to 0) on a consistent basis.ģ. That number, even when the battery is fully charged and showing 100% will almost always be 10-100 mAh lower than the FCC. That's on a brand new battery, the number varies from battery to battery but that's a rough estimate.Ģ.) RCC / Remaining Charge Capacity will vary when the machine is in use and not plugged into power. A couple of things:ġ.) FCC / Full Charge Capacity on the typical MacBook battery should be between 4650-4900 mAh. Wow, those are some pretty crazy system profiler logs from all of you. 187 charging cycles currently but think I have an imminent battery failure pending.
I have a 2 year old macbook that indicates 100% charged, green light indication on charging cord, but I know that the battery is not fully charged, and has less than an 30 minutes of life when disconnected.
As for the whole calibration thing, I did that procedure at least once a month, simply through general use and not deliberately.īattery also acting weird. Looking at some of the other posts here, I found out that the number of cycles in the battery should be around 500, and given 300 the capacity should be 80%? Anyways is there anything I could do to save my battery, or should i just get a new one? It's 2 years old btw. Two weeks ago I could get around 3 hours out of it (wifi on, brightness turned down by 2 marks) but now I struggle to get a whole hour.
