When should I replace my battery?
I just noticed the service battery warning on 10/14 and while I was able to calibrate it into the 80% range to temporarily cure it, I don’t feel like I’m going to get much time out of it even with a recalibration without seeing the warning come back. I may even get it back after recharging it (I never let it get this low; it slipped by me since I usually charge around 20-25%). While not shown as I have data but no screenshot, it was once at 80.9% (4,670mAh).
I remember from my 2009 17” the service battery message isn’t a death sentence, but I also knew that battery since I got that machine new. With this 13”, I don’t have a history to know how it’s been treated before I got it.
Overall, how soon should I start pricing a new battery out factoring in the excessive cycles? I don’t know how the previous owner(s?) charged it, but it looks like a classic near 0-100% charge pack.
Is this a good question?
