Hello, i have a macbook air 2011 that has a battery percentage of 86%.
5642 out of 6700 mah. should i consider replacing it? will it improve my battery life by a noticeable amount?
this battery is four years old today. has 464 charge cycles. thanks!
MacBook Air, OS X Yosemite (10.10.5)
Which year is your MBA from? Does it have a replaceable battery? Are those stats from a fully charged battery? Does System Information about the battery recommend you service the battery or does it say the battery is Normal?
battery health is 86% out of 100%. my macbook is from mid-2011. it does not recommend i change it, just wondering if my battery life will improve by replacing it with a new 100% health battery. ( will having 6700/6700 add a hour more of life compared with my current 5642mah out of 6700mah)
If battery health is reported Normal, then I would not replace it. However, your question about how long the battery will last is; the computer will run for a longer period of time with a new battery. Life would be the same as stated in the original specs for that model, whatever that was. I believe the model you have has a battery with a nominal life of 1000 cycles. You aren't close to that yet. However, Apple states that the battery is warranted to reach 1000 cycles at or before battery health is 80%. If you wait and see perhaps you will get a new battery for free (I can't promise that, btw.)
